Why do land breezes occur at night?

• Land cools off slower than water, so the air above water is cooler.

• Water cools off faster than land, so the air above land is warmer.

• Land heats up slower than water, so the air stays cooler during the day.

• Water cools off slower than land, so the air above water is warmer.

During the land breeze, what starts moving the cooler air out and warmer air in?

• conduction

• convection

• radiation

sea breeze

• cool air moves down a mountain slope towards a valley

• warm air rises up a mountain slope from a valley

• cool land air flows to the ocean at night, causing warm ocean air to rise

• cool ocean air flows to land during the day, causing warm land air to rise
