The Water Cycle

There is only a certain amount of water on Earth at all times, and it’s the same water that’s been on Earth for millions of years. That’s because of the water cycle. This book explains the major parts of the water cycle, including precipitation and how water is stored on Earth, through both clear, concise main text and colorful, helpful flow charts. Including key subjects to supplement the Earth science curriculum, the main text covers water power, the importance of water to life, and how water is recycled today.
