Question

Describe how land and sea breeze occur

Answer 1

During the day the land is heated by the sun causing the air above it to expand. The air becomes less dense therefore it rises. The space left is quickly filled by another cool air (generally from the sea since the land gets hot faster). This causes a cool breeze form the sea during the day. At night the land loses heat faster than the sea. The air above the sea rises since it is less dense and cool air from the land rushes to fill the gap. This causes a breeze blowing from the land to the sea.

Answer 2

SEA BREEZE

During day time the sun shines and provides heat equally to land and sea. But the land gets heated faster than the sea so the hot air present above the land goes up and the air remains empty there.

                     Then the air from sea which is not heated up still moves to that empty space such that the amount of air present in land is equal that to amount of air present above sea. That's how sea-breeze takes place.

LAND BREEZE

During night time the sun sets and land and sea gets cooled down . But the land gets cooled faster than the sea so the hot air present above the sea goes up and the air remains empty there.

                    Then the air from land which is cooled down moves to that empty space such that the amount of air present in land is equal that to amount of air present above sea. That's how land-breeze takes place.
