Term
What is a sea breeze?
Definition
During the day, the land gets hot and the water is cool. The hot air from the land starts to rise because it's less dense.While the hot air is up in the air, the cooler air spreads out, taking the hot air's place. Soon, the hot air cools down and falls back on to the water. This means that the old cool air is hotter than the old hot air. So, the old cool air rises and the cycle repeats
Term
