The Earth's atmosphere is divided into five layers based on temperature and composition. Each layer plays a crucial role in protecting life on Earth.

- The troposphere is the layer closest to the Earth's surface, extending up to about 10 kilometers.
- This layer is where all weather phenomena occur, such as clouds, precipitation, and storms.
- Temperature decreases with altitude in the troposphere.

- The stratosphere extends from the troposphere to about 50 kilometers above the Earth's surface.
- The ozone layer is located in the lower stratosphere and helps absorb harmful ultraviolet radiation from the sun.
- Temperature increases with altitude in the stratosphere due to the presence of the ozone layer.

- The mesosphere extends from the stratosphere to about 85 kilometers above the Earth's surface.
- This layer is where most meteoroids burn up upon entering the Earth's atmosphere.
- Temperature decreases with altitude in the mesosphere.

- The thermosphere extends from the mesosphere to about 600 kilometers above the Earth's surface.
- Temperatures in the thermosphere can reach thousands of degrees Celsius due to the absorption of solar radiation.
- This layer is where the International Space Station orbits the Earth.

- The exosphere is the outermost layer of the Earth's atmosphere, extending beyond the thermosphere.
- This layer gradually transitions into outer space and contains very few gas molecules.
- Satellites orbit the Earth within the exosphere.
