When air particles gain energy and rise into the atmosphere, how does this affect the air pressure on the earth's surface?

• It causes the air pressure to rise creating high pressure.

• It does not affect the air pressure on the earth's surface.

• It causes 6th grade students to forget to do their homework.

• It causes the air pressure to drop creating low pressure

What kind of air pressure does WARM air have?

• High pressure

• Low pressure

• conduction in the atmosphere

• convection currents in the atmosphere

• electricity in the atmosphere

The drawing below shows a sea breeze.

When is this type of wind pattern most likely to occur?

• during the night when the surface of the sea cools faster than the land

• during the day when the sea is as warm as the land

• during the night when the air above land is warmer than the air above the sea

• during the day when the land heats faster than the surface of the sea
