    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, [17] with some variation due

    en.wikipedia.org/wiki/Climate_system

    The atmosphere envelops the earth and extends hundreds of kilometres from the surface. It consists mostly of inert nitrogen (78%), oxygen (21%) and argon (0.9%). [4] Some trace gases in the atmosphere, such as water vapour and carbon dioxide, are the gases most important for the workings of the climate system, as they are greenhouse gases which allow visible light from the Sun to penetrate to ...

  5. Atmosphere - Wikipedia

    en.wikipedia.org/wiki/Atmosphere

    The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition of the atmosphere of the Earth is the product of billions of years of biochemical modification of the paleoatmosphere by living ...

  6. Aeronomy - Wikipedia

    en.wikipedia.org/wiki/Aeronomy

    Planetary aeronomy studies the regions of the atmospheres of other planets [5] that correspond to the Earth's mesosphere, thermosphere, exosphere, and ionosphere. [6] In some cases, a planet's entire atmosphere may consist only of what on Earth constitutes the upper atmosphere, or only a portion of it.
