27.	I got a question in my class test.The question was:With the help of three examples,explain the movement of air.I wrote the answer as the following : Sea breeze:When land gets heated,warm air rises and cold air from sea come towards the land. (The land here is a low pressure area. Sea is a high pressure area.This shoes that air moves from high pressure area to low pressure area.) Air coming from poles towards equator:Equator area receive high heat from the sun. As a result,it becomes a low pressure area and rises up. The cold air from the polar regions come towards the equator . (Here,polar region is a region of high pressure.) No winds at hill stations:On hill ststions,there will be no wind because there is high air pressure.Air moves from a region of high air pressure to low air pressure.So, there will not be any wind in hill stations. Is this correct? If not,why not??
