water absorbs less heat than rock or metal does. if you have a small island in the middle of the ocean, then it will get colder than a continent because it is surrounded by water. then the atmoshere around that area will all be colder than the atmoshere over a large continent.
air masses move because cold air is heavier than warm air. so if you have an area of warm air next to an area of cold air, you get this kind of movement

The temperature and density of the air masses. the air masses moves when hot air and cold air gets together
it moves to the east coast
Air moves in a spiraling pattern from centers of high pressure toward centers of low pressure.

Continental air masses form in the United States

why is the united states not a great place for air masses to form
Weather is caused by the interaction of air,water,and sun. This forms air masses which can soon form fronts where air moves from high pressure areas to low pressure areas.
