Answer 1

Explanation:

spheres’. Each layer is characterized by a different gradient of temperature as a function of altitude.

The troposphere between0andabout15kilometres is the first layer above the Earth’s surface and contains approximately 85 to 90 % of the mass of the Earth’s atmosphere.

The stratosphere starts just above the troposphere and extends to 50 kilometres 31miles high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.

The mesosphere starts just above the stratosphere and extends to 85 kilometres 53miles high. Meteors burn up in this layer.

The thermosphere starts just above the mesosphere and extends to 600 kilometres 372miles high. Aurora and satellites occur in this layer.

The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometres 30miles above the surface
