From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth's troposphere extends from Earth's surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth's poles and higher at the equator.
The Earth's atmosphere is divided into five layers, based on temperature:
* **Troposphere:** The troposphere is the lowest layer of the atmosphere and extends from the Earth's surface to about 10 kilometers (6.2 miles) above sea level. It contains about 75% of the Earth's atmosphere and is where most of our weather occurs.
* **Stratosphere:** The stratosphere extends from the top of the troposphere to about 50 kilometers (31 miles) above sea level. It contains the ozone layer, which protects us from harmful ultraviolet radiation from the sun.
* **Mesosphere:** The mesosphere extends from the top of the stratosphere to about 80 kilometers (50 miles) above sea level. It is the coldest layer of the atmosphere, where temperatures can drop to below -100 degrees Celsius (-148 degrees Fahrenheit).
* **Thermosphere:** The thermosphere extends from the top of the mesosphere to about 700 kilometers (435 miles) above sea level. It is the hottest layer of the atmosphere, where temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit).
* **Exosphere:** The exosphere is the outermost layer of the atmosphere and extends from the top of the thermosphere to the edge of space. It is a very thin layer of atmosphere, where particles are constantly escaping into space.
The following table shows the different layers of the atmosphere and their extent:
| Layer | Extent |
| Troposphere | 0-10 km |
| Stratosphere | 10-50 km |
| Mesosphere | 50-80 km |
| Thermosphere | 80-700 km |
| Exosphere | 700-10,000 km |
The atmosphere is important for life on Earth. It protects us from harmful radiation from the sun, it regulates the Earth's temperature, and it provides the oxygen that we breathe.
