Composition and Layers of the Atmosphere

1. The BEST description of the troposphere is the layer of the atmosphere with the

• most ozone

• highest altitude

• greatest density

• coldest temperature

2. True or False: As you increase in altitude, the temperature of the air decreases because the air molecules become less dense.
