Water cycle

• The water cycle begins when the sun shines brightly and heats up water, causing it to change into water vapor and evaporate in the heat of the sun.
• Plants and soil also lose water in the form of water vapor, a process known as transpiration.
• As the water vapors from land and sea rise up in the air, they lose their heat and cool down in the form of little water droplets, forming clouds.
• As the clouds get heavier, more water vapor condenses, forming bigger droplets and falling back to the earth's surface as rain.
• The water that falls as rain goes back to the land, seas, rivers, lakes, and oceans.
• When the sun comes up again, the water evaporates again, beginning the cycle again.
• The water cycle is the continuous movement of water from the earth's surface to the air and back to the earth's surface again, involving changes in the state of water through evaporation and condensation.
• The water cycle is important because it ensures that water on the earth will not run out and living things have a constant supply of fresh water.
