The Water Cycle

Introduction

The water cycle is the continuous journey water takes from the sea, to the sky, to the land and back to the sea.

The movement of water around our planet is very important to life. It supports plants and animals. Powered by the Sun, the water cycle is happening all the time, though some parts of the cycle take hundreds of years.

Water is everywhere! It is in your body, in the ground, and even in the sky. Let's see how the water cycle works!

Conclusion
Interesting Water Cycle Facts:
Water is a resource that cannot be created by man.
The sun is the driving force of the water cycle.
Whenever water changes from one state to another and moves from one place to another, it either gives off energy or absorbs energy.
Transpiration is the process by which water evaporates from plant leaves into the atmosphere.
When water evaporates into the atmosphere, it cools and condenses to form clouds through a process called condensation.
