Figure 1: Earth's Atmospheric Layers
1. In which atmospheric layer does most weather occur?
Stratosphere
Troposphere
Mesosphere
Thermosphere
2. Which layer contains the ozone layer, protecting Earth from harmful UV radiation?
Troposphere
Stratosphere
Mesosphere
Exosphere
3. The is the outermost layer of Earth's atmosphere, where the atmosphere thins out and merges with outer space.
4. Meteors typically burn up in the due to friction with atmospheric gases.
5. The temperature in the thermosphere can reach extremely high values, but it would not feel hot to a human because of the low of the gas molecules.
6. The temperature generally decreases with increasing altitude in the stratosphere.
True
False
7. The ionosphere is a distinct atmospheric layer separate from the thermosphere.
True
False
8. Describe the primary function of the ozone layer and explain its importance to life on Earth.
9. Explain why the temperature profile of the thermosphere is misleading when considering its effect on a human body.
Match each atmospheric layer with its primary characteristic or phenomenon.
