Question

Differentiate between land breeze and sea breeze

Answer 1

In the day, the sun heats up the land faster, and so the air above the land has a lower pressure than the air over the ocean. This causes a breeze from the higher pressure air over the ocean towards the lower pressure air over the land. This is a sea breeze.
At night time, the air above the land cools down faster than the air above the ocean. This means that the air above the land now has a higher pressure because cold air sinks. So the wind will blow from the high pressure air above the land to the low pressure air above the ocean. This is a land breeze.

Answer 2

Land breeze - The breeze that blows from the land towards the sea after sunset. 
Sea breeze- The breeze that blows from the sea toward the land before sunset.
