Earth’s water is always on the move. It races down rivers. It churns in oceans and whirls through the air. Sometimes, a little water settles down to rest. The places where it rests are called lakes.
Lakes are bodies of water with land around them. They are all over the world, and sometimes we call them called “seas.” The Caspian Sea, between Russia and Central Asia, is a lake. In Israel, the Sea of Galilee and the Dead Sea, between Jordan and Israel, are also lakes.
Most lakes don’t last very long. After a few thousand years, they fill up with sediment. Or shifts in the Earth’s surface drain them. Then the water moves on to a new place.
