What Conditions affect the Water Cycle? Unit D * Chapter 11 * Section 2 Pages 342-347 Objectives Describe the stages of the water cycle. Describe how the water cycle relates to weather. The water cycle has processes • Evaporation • Condensation • Precipitation Evaporation • The sun dries up a puddle of water by making it “sweat”. • The “sweat” is called water vapor. • Water vapor is water in the form of a gas. • Evaporation is the process of water turning from liquid to gas. • Most of the time, we cannot see evaporation! Condensation • Once water vapor in the air becomes cold, it changes back into liquid and forms clouds. • This is called condensation. Experiment with condensation! On a warm day pour a cold glass of water and watch what happens. The water that forms on the outside of the glass is the product of condensation! Humidity • The amount of water vapor in the air Precipitation • When so much water has condensed that the air can no longer hold it, it becomes precipitation. • Precipitation is water falling back onto to the earth. • Examples include: rain, sleet, snow, and hail Then the water cycle starts all over again! THE WATER CYCLE 4. Precipitationwater falls to form rivers. 3 4 3. Water vapor condenses to form clouds 2 2. Water vapor is carried up into the air. 5 5. Rivers flow into the sea 1. Water evaporates 1 Our world uses the same water over and over again by moving it around in a process called the water cycle. All Living Organisms Need Water Water can land on the ground and be used by plants, animals, and people. Go and get a glass of water. What do you know about this glass of water? Where did the water come from? Could this dinosaur have had some of the water in this glass at one time? The same water you play with in the summer… has been around for years and years ! Prehistoric animals shared your water millions of years ago! Kings, queens, knights and princesses used the same water in their wells. Fresh water is a limited resource that people need to conserve and keep clean! Factors that affect the water cycle • Distance from the equator • Shape of the land • Landforms Get out your remotes!
