1. Troposphere: This is the lowest layer of the atmosphere and extends from the Earth's surface up to about 10 km. It is the layer where most of the weather and clouds occur.
2. Stratosphere: This layer extends from 10 km to about 50 km above the Earth's surface. It is the layer where most of the ozone is found.
3. Mesosphere: This layer extends from 50 km to about 80 km above the Earth's surface. It is the layer where meteors burn up.
4. Thermosphere: This layer extends from 80 km to about 600 km above the Earth's surface. It is the layer where auroras occur.
5. Exosphere: This is the outermost layer of the atmosphere and extends from 600 km to about 10,000 km above the Earth's surface. It is the layer where most of the particles escape into space.
