  2. Atmosphere of Earth - Wikipedia

    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, [23] with some variation due to weather.

  3. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    The layer has the largest concentration of nitrogen. The atmosphere of the Earth is in five layers: (i) the exosphere at 600+ km; (ii) the thermosphere at 600 km; (iii) the mesosphere at 95–120 km; (iv) the stratosphere at 50–60 km; and (v) the troposphere at 8–15 km.

  4. Atmosphere - Wikipedia

    en.wikipedia.org/wiki/Atmosphere

    The atmosphere of Earth is composed of layers with different properties, such as specific gaseous composition, temperature, and pressure. The troposphere is the lowest layer of the atmosphere. This extends from the planetary surface to the bottom of the stratosphere. The troposphere contains 75–80% of the mass of the atmosphere, [9] and is ...

  5. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    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 (/ ˈ s t r æ t ə ˌ s f ɪər,-t oʊ-/) is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere.

  6. Lower atmosphere - Wikipedia

    en.wikipedia.org/wiki/Lower_atmosphere

    Lower atmosphere is a collective term sometimes used to refer to various layers of the atmosphere of the Earth and corresponding regions of the atmospheres of other planets, and includes: The troposphere , which on Earth extends from the surface to an altitude of about 12 kilometres (7.5 mi)

  7. Tropopause - Wikipedia

    en.wikipedia.org/wiki/Tropopause

    The troposphere is the lowest layer of the Earth's atmosphere; it starts at the planetary boundary layer, and is the layer in which most weather phenomena occur. The troposphere contains the boundary layer, and ranges in height from an average of 9 km (5.6 mi; 30,000 ft) at the poles, to 17 km (11 mi; 56,000 ft) at the Equator.

  8. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending on latitude: for example, the troposphere is thicker in the tropics (about 16 ...

  9. Low-pressure area - Wikipedia

    en.wikipedia.org/wiki/Low-pressure_area

    In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are associated with lighter winds and clear skies.
