A sea breeze blows from the ocean toward the shore. Why does this occur?

• High pressure over the land causes a downdraft to occur.
• The tide carries the wind to the shore as it moves back and forth.
• Conduction of heat from the warm water produces wind from the ocean.
• Air over land heats faster than air over water, which causes convection.

How do differences in air pressure affect the movement of air?

• Air always moves from areas of high pressure to areas of low pressure.
• Air always moves from areas of low altitudes to high altitudes.
• Air always moves from areas of low pressure to areas of high pressure.
• Air always moves from east to west.

instrument that measures atmospheric (air) pressure

• thermometer

• barometer

• altimeter

• wind vane

A scientist measures an atmospheric pressure of approximately 995 millibars at an elevation of 153

meters. What would happen if the scientist took the reading at sea level?

• The pressure reading would be lower because the elevation would be lower.

• The pressure reading would be higher because the elevation would be lower.

• C. The pressure reading would be lower because the elevation would be higher.

• D. The pressure reading would be higher because the elevation would be higher.
