  2. Exosphere - Wikipedia

    en.wikipedia.org/wiki/Exosphere

    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 natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision ...

    Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are: Exosphere: The outermost layer of Earth's atmosphere extends from the exobase upward, mainly composed of hydrogen and helium.

  4. Upper atmosphere - Wikipedia

    en.wikipedia.org/wiki/Upper_atmosphere

    The exosphere, which on Earth lies between the altitudes of about 700 kilometres (435 mi) and 10,000 kilometres (6,200 mi) The ionosphere, an ionized portion of the upper atmosphere which includes the upper mesosphere, thermosphere, and lower exosphere and on Earth lies between the altitudes of 48 and 965 kilometres (30 and 600 mi)

  5. Thermopause - Wikipedia

    en.wikipedia.org/wiki/Thermopause

    As a lower boundary for the exosphere this boundary is also called the exobase. [1] The exact altitude varies by the energy inputs of location, time of day, solar flux, season, etc. and can be between 500 and 1,000 kilometres (310 and 620 mi) high at a given place and time because of these. A portion of the magnetosphere dips below this layer ...

    en.wikipedia.org/wiki/Ecosphere_(planetary)

    A view of the Earth's ecosphere. An ecosphere is a planetary contained ecological system. In this global ecosystem, the various forms of energy and matter that constitute a given planet interact on a continual basis. The forces of the four Fundamental interactions cause the various forms of matter to settle into identifiable layers. These ...

    Geosphere/Solid Earth – (Also sometimes a collective name for the lithosphere, the hydrosphere, the cryosphere, and the atmosphere) The union of all solid parts of Earth and the Inner of Earth. Pedosphere – The outermost layer of the Earth that is composed of soil and subject to soil formation processes; Outer layers By composition

    SpaceX’s rocket explosion in November 2023 created a massive hole in the Earth's ionosphere, providing scientists with a rare opportunity to study its effects.

  9. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The stratosphere is the second-lowest layer of Earth's atmosphere. It lies above the troposphere and is separated from it by the tropopause. This layer extends from the top of the troposphere at roughly 12 km (7.5 mi; 39,000 ft) above Earth's surface to the stratopause at an altitude of about 50 to 55 km (31 to 34 mi; 164,000 to 180,000 ft).
