Identify the layers of the atmosphere.

The atmosphere of Earth is divided into five main layers. These layers, starting from the surface of the Earth and moving upwards are:

1. Troposphere: This is the layer closest to the Earth's surface, where we live and where weather occurs. It extends up to about 8 kilometers at the poles and about 17 kilometers at the equator.

2. Stratosphere: Above the troposphere, extending up to about 50 kilometers above the Earth's surface. This layer holds the ozone layer, which protects us from harmful sun rays.

3. Mesosphere: This layer extends from the top of the stratosphere up to about 85 kilometers above the Earth. Meteors burn up in this layer upon entering Earth's atmosphere.

4. Thermosphere: This layer extends from the top of the mesosphere up to about 600 kilometers. The Northern and Southern lights occur in this layer.

5. Exosphere: This is the outermost layer, where the atmosphere merges into space. It starts around 600 kilometers above the Earth and goes up to about 10,000 kilometers.
