4 True/False Questions

1. Temperature → the lowest layer of the atmosphere

   True        False

2. Temperature Inversion → when the air at Earth's surface is colder than the air above, so convection does not occur

   True        False

3. Heat → causes the temperature to increase in the stratosphere

   True        False

4. Thermosphere → third layer; extends between about 50 and 90 kilometers above Earth's surface

   True        False
