Land and sea-breezes occur due to :

A. Conduction
B. Convection
C. Radiation
D. Tides
Answer» B. Convection
Explanation: During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.
