Convection Weather

At the seashore late in the afternoon on a hot day, a person often feels a strong breeze coming from the ocean because...

• the pounding waves generate air currents

• warm air over the ocean rushes in to replace the cool air that rises over the land

• the heavy, cool air over the ocean rushes in to replace the warm air that rises over the land

• there are no clouds to block the wind coming in from the ocean

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
