  2. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    In this way, Earth's atmosphere can be divided (called atmospheric stratification) into five main layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. [20] The altitudes of the five layers are: Exosphere: 700 to 10,000 km (440 to 6,200 miles) [21] Thermosphere: 80 to 700 km (50 to 440 miles) [22]

  3. Atmosphere - Wikipedia

    en.wikipedia.org/wiki/Atmosphere

    An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam' and σφαῖρα (sphaîra) 'sphere') [1] is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the ...

  4. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    The stratosphere image is dominated by blues and greens, which indicates a cooling over time. [1] Diagram showing the five primary layers of the Earth's atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are not to scale. The stratosphere (/ ˈstrætəˌsfɪər, - toʊ -/) is the second-lowest layer of ...

  5. Exosphere - Wikipedia

    en.wikipedia.org/wiki/Exosphere

    Exosphere. Diagram showing the five primary layers of the Earth's atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are to scale. From the Earth's surface to the top of the stratosphere (50km) is just under 1% of Earth's radius. The exosphere is a thin, atmosphere-like volume surrounding a planet or ...

  6. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    The troposphere is the lowest layer of the atmosphere of Earth. It contains 80% of the total mass of the planetary atmosphere and 99% of the total mass of water vapor and aerosols, and is where most weather phenomena occur. [1] From the planetary surface of the Earth, the average height of the troposphere is 18 km (11 mi; 59,000 ft) in the ...

  7. Climate system - Wikipedia

    en.wikipedia.org/wiki/Climate_system

    The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

  8. Atmosphere of Uranus - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Uranus

    The Uranian atmosphere can be divided into five main layers: the troposphere, between altitudes [a] of −300 and 50 km and pressures from 100 to 0.1 bar; the stratosphere, spanning altitudes between 50 and 4000 km and pressures of between 0.1 and 10 −10 bar; and the hot thermosphere (and exosphere) extending from an altitude of 4,056 km to ...

  9. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    The stratosphere receives its warmth from the sun and the ozone layer which absorbs ultraviolet radiation. The next layer, the mesosphere, extends from the stratopause to the mesopause (located at an altitude of 85 km (53 mi)). Temperatures in the mesosphere decrease with altitude, and are the coldest in the Earth's atmosphere. [5]
