Wind. The summer wind, came rolling in, from across the bay. What causes wind?. Uneven heating of the Earth’s surface causes some areas to be warmer than others Warmer air is less dense and moves. Coriolis Effect. The rotation of the Earth causes wind. Like a spinning ball.
The summer wind,
came rolling in,
from across the bay
In the polar regions, cold, dense air sinks and moves away from the poles.
Near 30 degrees. Earth’s rotation moves winds from west to east toward polar region
Air near the equator heats up and move to the poles
Air heats up and becomes less dense, causing low pressure and almost daily rain storms.
