Atmosphere

How are the layers of the atmosphere classified?

• Density
• Gases
• Humidity
• Temperature

The order of the layers of the atmosphere from earth's surface to space.

• stratosphere, troposphere, mesosphere, thermosphere
• troposphere, thermosphere, stratotosphere, mesosphere
• troposphere, stratosphere, mesosphere, thermosphere
• troposphere, stratosphere, thermosphere, mesosphere

Which atmospheric layer is the ozone layer found?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

As we go higher in  the atmosphere, the air pressure

• decreases
• increases
• does not change
• gets heavier

Why does air pressure differ around the earth?

• Cold air rises at the equator and warm air sinks at the poles.
• Cold air sinks at the equator and warm air rises at the poles.
• Warm air  air sinks at the equator and cold air rises at the poles.
• Warm air rises at the equator and cold air sinks at the poles.
