Best Answer: Because water heats and cools much slower than air, these large bodies of water have a moderating effect on land temperatures. In spring, when air temps over land are getting warmer, the body of water, which stays cooler much longer, cools the air immediately surrounding it. Likewise, in fall and winter, when cold air spreads over the land mass, these bodies of water retain their warmth, preventing temps from getting as cold around them. That is the effect that lakes have on land temperatures. The prevailing winds are also a large factor. Oceans provide land and sea breezes.
For example, air with a large amount of water vapor is less dense than dry air because the water molecule has less mass than either an individual nitrogen or oxygen molecule. Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earthâs surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles. At the poles, the cooler air sinks and moves back toward the equator.
