Atmosphere Notes Summary

Earth's atmosphere is made of 4 layers known as the Troposphere, Stratosphere, Mesosphere and Ionosphere. Air pressure decreases as you travel higher into Earth's atmosphere. Most weather occurs in the Troposphere. Solar radiation is the driving force of Earth's weather. Atmospheric gases and the presence of ozone and aerosols determine how much solar radiation reaches Earth's surface. Humidity is the amount of water vapor in the air. Clouds are condensed droplets of water.
