The sun makes the earth hot, but it cannot make the weather very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth rises.
Then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean, you feel the cool air when it moves in. You feel the wind, and the wind makes you feel cool.
Of course, scientists cannot answer all of our questions. If we ask, "Why is the ocean full of salt?" scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into the cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean.
