LAQ : Describe the layers of the atmosphere with a sketch

Question

Describe the layers of the atmosphere with a sketch.

Answer

The atmosphere is typically divided into five layers based on temperature changes with altitude. These layers, starting from the surface of the Earth, are:

1. The Troposphere – the lowest layer where we live and where weather occurs. It extends up to about 12 km (7.5 miles) in altitude.
2. The Stratosphere – contains the ozone layer which absorbs harmful UV radiation. It extends from the top of the troposphere to about 50 km (31 miles) in altitude.
3. The Mesosphere – the coldest layer of the atmosphere where temperatures can drop below -100°C (-148°F). It extends from the top of the stratosphere to about 85 km (53 miles) in altitude.
4. The Thermosphere – the layer where the auroras occur, and where the temperature can reach over 1000°C (1832°F) due to the absorption of solar radiation. It extends from about 85 km (53 miles) to 600 km (373 miles) in altitude.
5. The Exosphere – the outermost layer of the atmosphere where the air is very thin and gradually merges with the vacuum of space. It extends from about 600 km (373 miles) to 10,000 km (6,200 miles) in altitude.
