The water we use every day is very old. Just like the Earth itself, it’s been around for billions of years. The Earth has a limited amount of water that always gets recycled. It is in a closed system. Since we do not lose or gain water from other sources, it’s important to protect the water we have.

The water cycle is a natural process that happens when water rotates through different forms (solid, liquid, or vapor). The process improves the quality of water. However, people do things that create water pollution.
