Read the following article and answer the question. Article: When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool. Why?

When a rock gets very hot or very cool, it cracks , and rain falls into the cracks. The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask "What happens to the salt in the ocean? The ocean does not get saltier every year. " scientists are not sure about the answer to the question. We know a lot about our world.
