The Earth's Atmosphere
The Earth's atmosphere has five layers, which is the Exosphere, the Thermosphere, the Mesosphere, the Stratosphere, and the closest one to Earth Troposphere.
Exosphere is the layer where Earth's atmosphere meets the outer space. It ranges from about 500-1000 km almost up to 10,000 km. Only the lightest gases, mainly hydrogen, with some helium and carbon dioxide found their way into the earth's exosphere. The temperature in exosphere is
Thermosphere has space shuttle orbits in that area.Its temperature could reach up to 230 c.(440 F). Within the thermosphere there are the ionosphere and the magnetosphere.
Mesosphere is 50 to 80 km above Earths surface. The temperature in Mesosphere will drop to as low as -90C(-130F) at the top of the layer.
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.Although the temperature may be −60 °C (−76 °F; 210 K) at the tropopause, the top of the stratosphere is much warmer, and may be near 0 °C.
The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km, although this altitude actually varies from about 9 km (30,000 ft) at the poles to 17 km (56,000 ft) at the equator, with some variation due to weather. The troposphere is bounded above by the tropopause, a boundary marked by stable temperatures.
