• convection

• radiation

• Insolation

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
