The purpose of this section is to provide background information for teachers. It is absorbed mostly by the tropical oceans and transported by the oceans and atmosphere to cold regions.
Most heat is carried as water vapor.
When the water rains out of the atmosphere, it warms the atmosphere. Much less is evaporated from lakes, rivers, soils, and vegetation on land. The evaporated water eventually condenses and falls as rain or snow over both land and ocean. In other words, more water evaporates from the ocean than reenters it as rain or snow. This is good for us as that is where most of the freshwater supply for Earth comes from.
