BR 12 The WATER CYCLE

I read a book today. The book name is " The WATER CYCLE". Why I read this book because it has heavy rain in recent days. Cause the heavy rain, there were numerous mudslides in various regions in Japan. I want to know about rain more. There are four stages in the water cycle. Evaporatrion, condensation precipiation runoff. Rain starts as a liquid in the ocean or a lake. It is then heated and changed into a gas and rises to the sky to form clouds. As cloud cool, the gas forms a liquid again. The liquid becomes too heavy to stay in the air so it falls to Earth. The liquid runs back into the ocean or lake. I understand the water cycle. If you want to know about rain, please read this book.
