The Water Cycle: Oceans describes how most of the world’s water supply is stored long-term in Earth’s oceans, and that the volume of the oceans changes slowly over time. A map of eastern North America shows the location of the coastline 20,000 years ago, when water was stored on land in ice sheets, compared with the modern coastline. Ocean currents, including the Kuroshio Current off the coast of Japan and the Gulf Stream in the North Atlantic are described.
