Atmosphere and Air Pressure

The layers of air that surround Earth are called the-

• sky

• troposphere

• ozone

• atmosphere

As altitude (height) increases, air pressure

• increases

• decreases

• stays the same

If you are standing at the BOTTOM of the mountain there is...

• higher air pressure

• lower air pressure

Which is not a fact about the troposphere?

• Air pressure decreases as you move higher up in this layer

• Planes usually fly in this layer

• Most weather occurs in this layer

• Most of life exists in this layer

What decreases as you go up in the atmosphere?

• Altitude

• Atmosphere

• Meteors

• Air Pressure

Generally, as altitude increases, what happens to air pressure?

• It increases.

• It decreases.

• It stays the same.

• It changes within each atmosphere layer.

the pressure caused by the weight of the atmosphere

• atmospheric pressure

• high pressure

• low pressure

• climate

• global winds

How does air pressure change as you climb a mountain?

• it decreases (less air pressure)

• it increases (more air pressure)

• stays the same

• the temperature gets warmer

What happens to the density (thickness)/ air pressure of the air as you increase in altitude?

• density increases

• density decreases

• density stays the same

• density disappears

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.
