[181] If all of Earth's crustal surface were at the same elevation as a smooth sphere, the depth of the resulting world ocean would be 2.7 to 2.8 km (1.68 to 1.74 mi). This hypothesis has been termed "Snowball Earth", and it is of particular interest because it preceded the Cambrian explosion, when multicellular life forms significantly increased in complexity. [63] Among the earliest fossil evidence for life is microbial mat fossils found in 3.48 billion-year-old sandstone in Western Australia,[64] biogenic graphite found in 3.7 billion-year-old metasedimentary rocks in Western Greenland,[65] and remains of biotic material found in 4.1 billion-year-old rocks in Western Australia. Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. The most abundant silicate minerals on Earth's surface include quartz, feldspars, amphibole, mica, pyroxene and olivine. [266] Lord Kelvin used thermodynamics to estimate the age of Earth to be between 20 million and 400 million years in 1864, sparking a vigorous debate on the subject; it was only when radioactivity and radioactive dating were discovered in the late 19th and early 20th centuries that a reliable mechanism for determining Earth's age was established, proving the planet to be billions of years old.[267][268]. The combination of these processes recycles the oceanic crust back into the mantle. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. [240] In total, about 550 people have visited outer space and reached orbit as of November 2018[update], and, of these, twelve have walked on the Moon.

The soil covers approximately a third of the whole Earth’s surface, with a thickness that ranges from tens of metres to a minimum of few centimetres, according to the intensity and duration of the rock changing processes. The changing Earth–Sun distance causes an increase of about 6.8% in solar energy reaching Earth at perihelion relative to aphelion. Without this heat-retention effect, the average surface temperature would be −18 °C (0 °F), in contrast to the current +15 °C (59 °F),[197] and life on Earth probably would not exist in its current form.

A little attention to the form of the earth’s surface shows that it has two parts—oceans and continents. Again. The final major mode of heat loss is through conduction through the lithosphere, the majority of which occurs under the oceans because the crust there is much thinner than that of the continents.

Classification of Air Masses. [26], Historically, earth has been written in lowercase. Flow of the liquid outer core is responsible for Earth’s magnetic field. Half of that land area is desert (14%),[236] high mountains (27%),[237] or other unsuitable terrains. In winter, the climate becomes cooler and the days shorter. [121], The total surface area of Earth is about 510 million km2 (197 million sq mi). [72][73] Apart from the proposed current Holocene extinction event, the most recent was 66 Ma, when an asteroid impact triggered the extinction of the non-avian dinosaurs and other large reptiles, but largely spared small animals such as insects, mammals, lizards and birds. Solar System → Local Interstellar Cloud → Local Bubble → Gould Belt → Orion Arm → Milky Way → Milky Way subgroup → Local Group → Local Sheet → Virgo Supercluster → Laniakea Supercluster → Observable universe → UniverseEach arrow (→) may be read as "within" or "part of". [233] 68% of the land mass of the world is in the Northern Hemisphere. Language. [235], It is estimated that one-eighth of Earth's surface is suitable for humans to live on – three-quarters of Earth's surface is covered by oceans, leaving one-quarter as land. [61] This change enabled the proliferation of aerobic organisms and, indirectly, the formation of the ozone layer due to the subsequent conversion of atmospheric O2 into O3. Types of soil and classification. [58] The Last Glacial Period, colloquially called the "last ice age", covered large parts of the continents, up to the middle latitudes, in ice and ended about 11,700 years ago. The scheme takes the form of triangular diagrams where each point of the triangle represents 100% of a mineral. From Earth itself comes earthly. The Composition and Structure of Earth. Paleontological evidence and computer simulations show that Earth's axial tilt is stabilized by tidal interactions with the Moon. "[27], Occasionally, the name Terra /ˈtɛrə/ is used in scientific writing and especially in science fiction to distinguish humanity's inhabited planet from others,[28] while in poetry Tellus /ˈtɛləs/ has been used to denote personification of the Earth. When a rock breaks, waves of energy are released and sent out through the earth. The two models and the data that support them can be reconciled by large-scale recycling of the continental crust, particularly during the early stages of Earth's history. Ask Question Asked 2 years, 10 months ago. [38], Estimates of the age of the Moon range from 4.5 Ga to significantly younger. [229], Earth's human population passed seven billion in the early 2010s,[231] and is projected to peak at around ten billion in the second half of the 21st century. The phylum is the next level following kingdom in the classification of living things. These same latitudes also experience a midnight sun, where the sun remains visible all day. The animal kingdom is the largest with approximately 1 million species. ", "How Are Fossil Fuels Extracted From the Ground? Only when we can map the world with the Koppen climate classification system we can answer these crucial questions. T – The live parts in the system have one or more direct connections to ground. [252] In 2019, 39 million km2 (15 million sq mi) of Earth's land surface consisted of forest and woodlands, 12 million km2 (4.6 million sq mi) was shrub and grassland, 40 million km2 (15 million sq mi) were used for animal feed production and grazing, and 11 million km2 (4.2 million sq mi) were cultivated as croplands. [88], The point on the surface farthest from Earth's center of mass is the summit of the equatorial Chimborazo volcano in Ecuador (6,384.4 km or 3,967.1 mi). [257] The Gaia Principle, developed mid-20th century, compared Earth's environments and life as a single self-regulating organism leading to broad stabilization of the conditions of habitability. New study results show that ocean heatwaves can provide enough fuel for hurricanes to gain momentum as they approach land. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Earth is the third planet from the Sun and the only astronomical object known to harbor life. Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. These components are also systems in their own right and they are tightly interconnected. A new study of Greenland's shrinking ice sheet reveals that many of the island's glaciers are not only retreating but are also undergoing other physical changes. ", "What Did Plato Think the Earth Looked Like? Each species belongs to a genus. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). [174], Earth's co-orbital asteroids population consists of quasi-satellites, objects with a horseshoe orbit and trojans. [145] Because Earth's solar day is now slightly longer than it was during the 19th century due to tidal deceleration, each day varies between 0 and 2 ms longer than the mean solar day. Correct 0. [209] Surface air temperature can rise to around 55 °C (131 °F) in hot deserts, such as Death Valley, and can fall as low as −89 °C (−128 °F) in Antarctica. Both of these motions are caused by the varying attraction of the Sun and the Moon on Earth's equatorial bulge. From the viewpoint of Earth system, we proposed a new basin classification scheme based on geodynamic mechanism—that is, lithospheric plate, sublithospheric, and Earth surface actions. The crust and the cold, rigid, top of the upper mantle are collectively known as the lithosphere, which is divided into independently moving tectonic plates.[103]. [200] Ocean currents are also important factors in determining climate, particularly the thermohaline circulation that distributes thermal energy from the equatorial oceans to the polar regions. [155] Above the Arctic Circle and below the Antarctic Circle there is no daylight at all for part of the year, causing a polar night, and this night extends for several months at the poles themselves. [207], Water vapor generated through surface evaporation is transported by circulatory patterns in the atmosphere. [261][262], Scientific investigation has resulted in several culturally transformative shifts in people's view of the planet. [146][147], Earth's rotation period relative to the fixed stars, called its stellar day by the International Earth Rotation and Reference Systems Service (IERS), is 86,164.0989 seconds of mean solar time (UT1), or 23h 56m 4.0989s. Earthworms are intriguing creatures that play a discreet, yet vital role in the natural cycle of life. For bodies near the celestial equator, this is equivalent to an apparent diameter of the Sun or the Moon every two minutes; from Earth's surface, the apparent sizes of the Sun and the Moon are approximately the same. [234] Partly due to the predominance of land mass, 90% of humans live in the Northern Hemisphere. The general workflow for classification is: Collect training data. A shift in these cues is already happening. [224], Extreme weather, such as tropical cyclones (including hurricanes and typhoons), occurs over most of Earth's surface and has a large impact on life in those areas. 1.9. [171] Some theorists think that without this stabilization against the torques applied by the Sun and planets to Earth's equatorial bulge, the rotational axis might be chaotically unstable, exhibiting large changes over millions of years, as is the case for Mars, though this is disputed. A hierarchical system, it works like a series of nesting boxes (Fig. Ser. 7. Sentinel-6 Michael Freilich, a joint U.S.-European satellite built to measure global sea surface height, has sent back its first measurements of sea level. These are seismic waves, the waves of energy produced by an earthquake. [138] Charged particles are contained within the magnetosphere; the plasmasphere is defined by low-energy particles that essentially follow magnetic field lines as Earth rotates. Each species belongs to a genus. As with Roman Terra/Tellūs and Greek Gaia, Earth may have been a personified goddess in Germanic paganism: late Norse mythology included Jörð ('Earth'), a giantess often given as the mother of Thor. ; Organisms can also be classified according to the manner in which they derive their life energy, or nutritional mode—chemoheterotrophs, chemoautotrophs, photoheterotrophs, and photoautotrophs, for example. [43], Earth's atmosphere and oceans were formed by volcanic activity and outgassing. Geography. [47] By 3.5 Ga, Earth's magnetic field was established, which helped prevent the atmosphere from being stripped away by the solar wind. [70][71] Following the Cambrian explosion, 535 Ma, there have been at least five major mass extinctions and many minor ones. [106] At the center, the temperature may be up to 6,000 °C (10,830 °F),[107] and the pressure could reach 360 GPa (52 million psi). The smallest ones are A-class (near background levels), followed by B, C, M and X. [60] The evolution of photosynthesis allowed the Sun's energy to be harvested directly by life forms. People rely on their knowledge of classification to understand what different species are like. [166] The same effect on the Moon has led to its tidal locking: its rotation period is the same as the time it takes to orbit Earth. [116], As the tectonic plates migrate, oceanic crust is subducted under the leading edges of the plates at convergent boundaries. Could another one start? EARTH FROM SPACE | Australian Classification … In this BiologyWise article, we present to you important information about the biological classification (taxonomy) and characteristics of the common earthworm. The continents later recombined to form Pannotia at 600–540 Ma, then finally Pangaea, which also began to break apart at 180 Ma. The fastest-moving plates are the oceanic plates, with the Cocos Plate advancing at a rate of 75 mm/a (3.0 in/year)[120] and the Pacific Plate moving 52–69 mm/a (2.0–2.7 in/year). The planets of the modern solar system are grouped into several different and sometimes overlapping classifications, as illustrated in the following figure: The planets inside the orbit of the earth are called the Inferior Planets : Mercury and Venus. [41], The gravitational attraction between Earth and the Moon causes tides on Earth. [243] The farthest that humans have traveled from Earth is 400,171 km (248,655 mi), achieved during the Apollo 13 mission in 1970. Over millions of years, these tiny modifications—and the lengthening of Earth's day by about 23 µs/yr—add up to significant changes. The remaining 71% is covered with water, mostly by oceans but also by lakes, rivers and other fresh water, which together constitute the hydrosphere. As of 4 January 2018, the United States Strategic Command tracked a total of 18,835 artificial objects, mostly debris. [5][152], The Hill sphere, or the sphere of gravitational influence, of Earth is about 1.5 million km (930,000 mi) in radius. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. Class M (terrestrial) Class N (sulfuric) Class R (a rogue planet, not as habitable as a terrestrial planet) Class T (gas giant) Class Y (toxic atmosphere, high temperatures) Earth's rotational velocity also varies in a phenomenon known as length-of-day variation. Director, NASA Planetary Science Division: Classification Of Surveying: A. [104] Earth's inner core may be rotating at a slightly higher angular velocity than the remainder of the planet, advancing by 0.1–0.5° per year, although both somewhat higher and much lower rates have also been proposed.

Its axial tilt does undergo nutation; a slight, irregular motion with a main period of 18.6 years. [130][131] Close to 40% of Earth's land surface is used for agriculture, or an estimated 16.7 million km2 (6.4 million sq mi) of cropland and 33.5 million km2 (12.9 million sq mi) of pastureland. When atmospheric conditions permit an uplift of warm, humid air, this water condenses and falls to the surface as precipitation. You need to be a group member to play the tournament. Check out our section on climate change below to … Of the earth’s surface, an area of 148 million square km, i.e., 2/7th part, is covered by land and the remaining 361 million sq km, i.e., 5/7th part is covered by oceans. This diagram illustrates the nested hierarchy used in modern biological classification. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy. Bill Dunford. Practice. Active 3 months ago. The mean height of land above sea level is about 797 m (2,615 ft). Three-quarters of the atmosphere's mass is contained within the first 11 km (6.8 mi) of the surface. Share it! Amanda Barnett [172][173], Viewed from Earth, the Moon is just far enough away to have almost the same apparent-sized disk as the Sun. Press play! [46] In this model, atmospheric greenhouse gases kept the oceans from freezing when the newly forming Sun had only 70% of its current luminosity. Classification of igneous rocks can be based on their predominant grain size. Ask Question Asked 6 years, 1 month ago. the following code … Mountains here, forests there, a river, a swamp etc. [192], The atmospheric pressure at Earth's sea level averages 101.325 kPa (14.696 psi),[193] with a scale height of about 8.5 km (5.3 mi). Create Assignment. [102] The thickness of the crust varies from about 6 kilometres (3.7 mi) under the oceans to 30–50 km (19–31 mi) for the continents. The M.I.T. Scientific name: Lumbrucis terrestris •Kingdom: Animalia. The wind transports the cold or the heat of the ocean to the land. Other notable plates include the Arabian Plate, the Caribbean Plate, the Nazca Plate off the west coast of South America and the Scotia Plate in the southern Atlantic Ocean. (ii) Classification based on material of construction: (a) Earth and rock fill dams are constructed of loose earth (ranging from fine material to big rock pieces) without any binding material. The major heat-producing isotopes within Earth are potassium-40, uranium-238, and thorium-232. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats. As a red giant, the Sun will lose roughly 30% of its mass, so, without tidal effects, Earth will move to an orbit 1.7 AU (250 million km; 160 million mi) from the Sun when the star reaches its maximum radius. Sentinel-6 Michael Freilich, the latest in a series of spacecraft designed to monitor our oceans, is ready for launch. [232] Most of the growth is expected to take place in sub-Saharan Africa. Earth provides liquid water—an environment where complex organic molecules can assemble and interact, and sufficient energy to sustain metabolism. 0%. The planets inside the orbit of the earth are called the Inferior Planets: Mercury and Venus. The Kármán line, defined as 100 km above Earth's surface, is a working definition for the boundary between the atmosphere and outer space. A layer of liquid iron and nickel (and other elements) beneath the mesosphere. 0:00.0. 1 Jun, 2020 Sound On/Off. An earth dam having its major portion built of rocks is called rock fill dam. The orbital and axial planes are not precisely aligned: Earth's axis is tilted some 23.44 degrees from the perpendicular to the Earth–Sun plane (the ecliptic), and the Earth–Moon plane is tilted up to ±5.1 degrees against the Earth–Sun plane. Climate classification, the formalization of systems that recognize, clarify, and simplify climatic similarities and differences between geographic areas in order to enhance the scientific understanding of climates. A half billion years later, the last common ancestor of all current life arose. The Moon will appear full from Monday evening through Thursday morning. [133], The main part of Earth's magnetic field is generated in the core, the site of a dynamo process that converts the kinetic energy of thermally and compositionally driven convection into electrical and magnetic field energy. Biologists have identified approximately 1.3 million species on Earth. The first continental crust, which was more felsic in composition, formed by the partial melting of this mafic crust. Biologists have identified approximately 1.3 million species on Earth. [5] A dry atmosphere is composed of 78.084% nitrogen, 20.946% oxygen, 0.934% argon, and trace amounts of carbon dioxide and other gaseous molecules. Important changes in crystal structure within the mantle occur at 410 and 660 km (250 and 410 mi) below the surface, spanning a transition zone that separates the upper and lower mantle. [228] This is driving changes such as the melting of glaciers and ice sheets, a global rise in average sea levels, and significant shifts in weather. [54], New continental crust forms as a result of plate tectonics, a process ultimately driven by the continuous loss of heat from Earth's interior. [8] There are also inoperative satellites, including Vanguard 1, the oldest satellite currently in orbit, and over 16,000 pieces of tracked space debris. [221], A planet that can sustain life is termed habitable, even if life did not originate there. [55], The most recent pattern of ice ages began about 40 Ma,[56] and then intensified during the Pleistocene about 3 Ma. [78] Earth's expected long-term future is tied to that of the Sun. There is a small flattening at the poles and bulging around the equator due to Earth's rotation. In the Northern Hemisphere, winter solstice currently occurs around 21 December; summer solstice is near 21 June, spring equinox is around 20 March and autumnal equinox is about 22 or 23 September. The common system categories are defined below using a 3-letter classification (based on IEE Standards).. [62] True multicellular organisms formed as cells within colonies became increasingly specialized. Main belt asteroids – These include the majority of asteroids in the solar system and are between the planets of Mars and Jupiter. 3.48 Billion-Year-Old Dresser Formation, Pilbara, Western Australia", "Hints of life on what was thought to be desolate early Earth", "Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon", "Oldest fossils ever found show life on Earth began before 3.5 billion years ago", "SIMS analyses of the oldest known assemblage of microfossils document their taxon-correlated carbon isotope compositions", "Estimates of the magnitudes of major marine mass extinctions in earth history", "Freeze, Fry or Dry: How Long Has the Earth Got? The largest box is the domain, and all the other levels of classification fit withi… In the Southern Hemisphere, the situation is reversed, with the summer and winter solstices exchanged and the spring and autumnal equinox dates swapped. The flow of glaciers erodes the surface changing it dramatically, with the formation of U-shaped valleys and other landforms. Starting from the earlier years of the human history generally to evaluate the intensity of the earthquakes is used to observe them according their effects to the environment (destruction, damages) But generally, in these comparison there were many subjective factors based on the human feelings. In addition to an annual component to this motion, there is a 14-month cycle called the Chandler wobble. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions. [238][239], The first human to orbit Earth was Yuri Gagarin on 12 April 1961. It ta… The remaining 29.2%, or 148.94 million km2 (57.51 million sq mi), not covered by water has terrain that varies greatly from place to place and consists of mountains, deserts, plains, plateaus, and other landforms. [263][264] Earth was generally believed to be the center of the universe until the 16th century, when scientists first conclusively demonstrated that it was a moving object, comparable to the other planets in the Solar System. Dr. Lori Glaze [170], The Moon may have dramatically affected the development of life by moderating the planet's climate. [4] Thus the sidereal day is shorter than the stellar day by about 8.4 ms.[148], Apart from meteors within the atmosphere and low-orbiting satellites, the main apparent motion of celestial bodies in Earth's sky is to the west at a rate of 15°/h = 15'/min. [232] Human population density varies widely around the world, but a majority live in Asia. A new video series introduces the people behind the Sentinel-6 Michael Freilich ocean-monitoring satellite. )", "Third rock from the Sun – restless Earth", "Chart: Globally, 70% of Freshwater is Used for Agriculture", "Fundamentals of Physical Geography (2nd Edition)", "World Meteorological Organization Assessment of the Purported World Record 58°C Temperature Extreme at El Azizia, Libya (13 September 1922)", "Record low surface air temperature at Vostok station, Antarctica", "Stratosphere and Weather; Discovery of the Stratosphere", "Presentation of the Karman separation line, used as the boundary separating Aeronautics and Astronautics", "The Aeronomy of Hydrogen in the Atmosphere of the Earth", 10.1175/1520-0469(1974)031<1118:TAOHIT>2.0.CO;2, "Interdependency between animal and plant species", "On the Generality of the Latitudinal Gradient", "Number of species on Earth tagged at 8.7 million", "Consensus on consensus: a synthesis of consensus estimates on human-caused global warming", "Various '7 billionth' babies celebrated worldwide", "World population in 2100 could be 2 billion below UN forecasts, study suggests", "What share of people will live in urban areas in the future? For its human aspects, see. But you don’t have to stop here for your journey to understand Earth’s climate. The taxonomic classification of “species” is the most specific you can get. [181] If all of Earth's crustal surface were at the same elevation as a smooth sphere, the depth of the resulting world ocean would be 2.7 to 2.8 km (1.68 to 1.74 mi). This hypothesis has been termed "Snowball Earth", and it is of particular interest because it preceded the Cambrian explosion, when multicellular life forms significantly increased in complexity. [63] Among the earliest fossil evidence for life is microbial mat fossils found in 3.48 billion-year-old sandstone in Western Australia,[64] biogenic graphite found in 3.7 billion-year-old metasedimentary rocks in Western Greenland,[65] and remains of biotic material found in 4.1 billion-year-old rocks in Western Australia. Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. The most abundant silicate minerals on Earth's surface include quartz, feldspars, amphibole, mica, pyroxene and olivine. [266] Lord Kelvin used thermodynamics to estimate the age of Earth to be between 20 million and 400 million years in 1864, sparking a vigorous debate on the subject; it was only when radioactivity and radioactive dating were discovered in the late 19th and early 20th centuries that a reliable mechanism for determining Earth's age was established, proving the planet to be billions of years old.[267][268]. The combination of these processes recycles the oceanic crust back into the mantle. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. [240] In total, about 550 people have visited outer space and reached orbit as of November 2018[update], and, of these, twelve have walked on the Moon.

Extrusive rocks … By Early Modern English, many nouns were capitalized, and the earth was also written the Earth, particularly when referenced along with other heavenly bodies. Multistage classification of multispectral earth observational data: the design approach. NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. [30], There are a number of adjectives for the planet Earth. Less boring classifications of earth-like terrain when making maps. [179], As of April 2020[update], there are 2,666 operational, human-made satellites orbiting Earth. D.C. in 1927. The soil covers approximately a third of the whole Earth’s surface, with a thickness that ranges from tens of metres to a minimum of few centimetres, according to the intensity and duration of the rock changing processes. The changing Earth–Sun distance causes an increase of about 6.8% in solar energy reaching Earth at perihelion relative to aphelion. Without this heat-retention effect, the average surface temperature would be −18 °C (0 °F), in contrast to the current +15 °C (59 °F),[197] and life on Earth probably would not exist in its current form. Density increases with depth, as described in the table on the right. [254], Human cultures have developed many views of the planet. (.DAT file (displays as plaintext in browser)), International Earth Rotation and Reference Systems Service, Moderate-Resolution Imaging Spectroradiometer, "Geoid, Topography and Distribution of Landforms", "General Definitions and Numerical Standards", "Surface area of our planet covered by oceans and continents.
