Explain how does the ozone layer helps life on Earth?

• Produces oxygen for atmosphere.

• Protects Earth from meteors.

• Absorbs damaging radiation from the sun.

• Reflects most of the sun's radiation to keep Earth cool.

Identify the atmospheric layer that contains the ozone.

• troposphere

• stratosphere

• mesosphere

• thermosphere

Recall the layer where the greatest atmospheric pressure occurs.

• troposphere

• stratosphere

• exosphere

• mesosphere

Why does all weather occur in troposphere?

• temperatures are warmer within the layer

• ozone protects layer from radiation

• largest, most stable layer

• water vapor condenses and precipitates before it can escape the layer
