The mixture of gases surrounding the Earth or other celestial body, held in place by gravity. It forms distinct layers at different heights. The Earth's atmosphere consists, in ascending order, of the troposphere (containing 90% of the atmosphere's mass), the stratosphere, the mesosphere, the thermosphere, and the exosphere. The atmosphere is composed primarily of nitrogen (78%) and oxygen (21%) and plays a major role in the water cycle , the nitrogen cycle , and the carbon cycle .
The region of the Earth's atmosphere lying above the stratosphere and below the thermosphere, from a height of about 50 km (31 mi) to about 80 km (50 mi) above the Earth's surface. In the mesosphere temperatures decrease with increasing altitude due to the decreasing absorption of ultraviolet radiation from the Sun. At the top of this region temperatures are around −95°C (−135.4°F). Most of the meteors that enter Earth's atmosphere burn up while passing through the mesosphere.
