Power Hour 34 Oceans, Rivers, and Lakes by Linda Ruggieri

 The water mixes with the salt and minerals. Then it flows into the oceans.

Scientists have discovered two other sources of salty ocean water. Some salt comes from underwater volcanoes. Other salt spurts from heated vents on the ocean floor. Most ocean salt, however, starts on land.Lakes are large bodies of water. They are surrounded by land. Lakes usually have fresh water, but some lakes have salt water. The Great Salt Lake in Utah is a saltwater lake. Lake water does not move from place to place. 

Rivers are filled with fresh water that moves from one place to another. The water in rivers comes mostly from rain. Rivers usually flow into oceans. Streams and creeks are also bodies of moving fresh water. They are smaller than rivers. Streams and creeks can come together and form larger streams or rivers.
