When incoming energy from the sun is absorbed, Earth warms. When energy is released from Earth into space, the planet cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including changes in greenhouse gasses; variations in the sun’s energy reaching Earth; and changes in the reflectivity of Earth’s atmosphere and surface.

The density of the atmospheric mass is much greater close to the surface and decreases rapidly with increasing altitude.

This section is a brief introduction to the layers of the atmosphere and the differences between climate and weather.
