Section Summary

I Earth's atmosphere is composed of several gases, primarily nitrogen and oxygen, and also contains small particles.

I Earth's atmosphere consists of five layers that differ in their compositions and temperatures.

I Solar energy reaches Earth's surface in the form of visible light and infrared waves.

I Solar energy absorbed by Earth's surface is transferred as thermal energy throughout the atmosphere.

Understand Main Ideas

1. iman4BHB Rank the gases in the atmosphere in order from most abundant to least abundant.

2. Name the four types of particles found in the atmosphere.

3. Compare and contrast the five layers that make up the atmosphere.

4. Explain why temperature increases with height in the stratosphere.

5. Compare how solar energy is absorbed and emitted by Earth's surface.

Think Critically

6. Predict whether a pot of water heated from the top would boil more quickly than a pot of water heated from the bottom. Explain your answer.

7. Conclude What might surface temperatures be like on a planet with no atmosphere?
