Question

what causes land and sea breezes

Answer 1

The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and theocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.

Answer 2

Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the landsurface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air.
