　　Water Cycle

　　The heat of the sun evaporates water from the oceans, seas, rivers

Answer 1

答案：
解析：

Water Cycle 　　The heat of the sun evaporates water from the oceans, seas, rivers and lakes. Water vapor is formed. 　　This rises and forms clouds in the air. As the clouds rise, they are cooled. The higher they rise, the more they are cooled. This causes more and more water vapor to condense. In this way, the little drops of water in the clouds get bigger and bigger until they are heavy enough to fall to the earth as rain. Some of rain water sinks into the ground. It may be used up by thirsty plants. Most of the water goes back to the rivers, seas and oceans. This process called the water cycle then starts all over again.
