Answer
At sea-shore during the day, cold air from the sea moves towards the land because the land gets more heated than the sea water. Hot air above the land rises up, and cold air from the sea moves towards the land. This is called sea breeze as shown in Fig.(a). At night, cold air from the land moves towards the sea because the land cools more quickly than the sea water. So hot air above the sea rises up and cold air from the land moves towards the sea. This is called land breeze as shown in Fig.(b)
