Explanation:

Troposphere: This is the lowest atmospheric layer and is about seven miles   (11 km) thick. Most clouds and weather are found in the troposphere. Stratosphere: The stratosphere is found from about 7 to 30 miles (11-48 kilometres) above the Earth’s surface. In this region of the atmosphere is the ozone layer found. Mesosphere: The mesosphere is above the stratosphere. Here the atmosphere is very rarefied, that is, thin, and the temperature is decreasing with altitude. Thermosphere: The thermosphere starts at about 55 kilometres. The temperature is quite hot. Exosphere: The exosphere is the region beyond the thermosphere. Ionosphere: The ionosphere overlaps the other atmospheric layers, from above the Earth. The air is ionized by the Sun’s ultraviolet light.
