True or false. Land and water absorb or lose the same amount of heat in the same period of time. | False. Land and water do not absorb or lose the same amount of heat in the same period of time. |
Sea breeze | During the day, land gets heated quickly but the sea does not. When the air above the land gets heated, it rises as hot air is lighter. Cool air over the sea rushes in to take its place. Thus a cool breeze blows towards the land during the day. |
Land breeze | At night, the land cools down faster than the sea. So the sea is warmer than the land. The hot air above the sea rises. The cooler air from the land blows towards the sea to take its place. |
