Unit #3 Water covers most of the Earth's surface. It circulates between oceans and land in a process called the water cycle.
Key Concept-The Water Cycle
National Standard-Water, which covers the majority of the Earth's surface, circulates through the crust, oceans, and atmosphere in what is know as the "water cycle". Water evaporates from the earths surface, rises and cools as it moves to higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and rocks underground.
