Earth's Atmosphere consists of gases built up from billions of years of volcanic eruptions mixed with suspended liquid and solid particles such as water droplets, ice crystals and dust particles. Gravity holds our atmosphere in place while differential solar heating reaching a tilted rotating sphere makes for an active and interesting system uniquely capable of supporting life on Earth.

In this lesson you will learn:

• The composition of Earth's Atmosphere
• More about the amazing water molecule
• Earth's Energy Cycle & Energy Budget
