116 CHAPTER 11 FRESH WATER

117 11.1 THE WATER CYCLE Identify how Earths water is distributed among saltwater and freshwater sources. Describe how Earths water moves through the water cycle.

118 ENGAGE/EXPLORE Have a student describe a rainstorm. Where does the water come from that falls as rain? How does the water get into the clouds?

119 DISCOVER - WHERE DOES THE WATER COME FROM? Fill a glass with ice cubes and water, being careful not to spill any water. Wait 5 minutes. Observe the outside of the glass and the surface it was sitting on.

120 INTRODUCTION - NOTES Why is Earth called the water planet? From space, this is the image that astronauts see. Oceans cover nearly 71 percent of Earths surface.

121 I. WATER ON EARTH - DEMO

122 Most of Earths water is 97% percent salt water that is found in oceans. Only 3% is fresh water. 76% ice masses.037% atmosphere (water vapor in a gaseous form. Less than 1% is fresh water available for human use. Some of the Earths fresh water is deep underground.

123 A. OCEANS All Earths oceans are connected to form a single world ocean.

124 B. ICE - ARTIC AND ANTARCTICA Icebergs are formed from frozen fresh water.

125 D. BELOW EARTHS SURFACE Groundwater - water that fills the cracks and spaces in underground soil and rock layers. Far more fresh water is located underground than in all Earths rivers and lakes.

126 II. THE WATER CYCLE Water Cycle - the continuous process by which water moves through the living and nonliving parts of the environment. All the water on Earth has been through the water cycle.

127 II. THE WATER CYCLE In the water cycle, water moves from bodies of water, land, and living things on Earths surface to the atmosphere and back to Earths surface. The sun is the source of energy that drive the water cycle. Prentice Hall video and activity

128 A. WATER EVAPORATES Exploring the water cycle p Evaporation - the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state. Ocean water that evaporates isnt salty because the salt remains in the ocean.

129

130 PLANTS Plants take in water by drawing in water form the soil through their roots. Transpiration - water given off through the leaves as water vapor. Plants give off a large amount of water.

131 C. WATER FALLS AS PRECIPITATION Precipitation - water that falls to Earth as rain, snow, hail, or sleet. Precipitation occurs when water droplets in a cloud grow larger and larger. They become so heavy that they fall to Earth.

132 Precipitation is the source of all fresh water on and below Earths surface. The water cycle renews the usable supply of fresh water on Earth. The total amount of water on Earth has remained fairly constant and balanced. Water cycle song - Clementine

133 Most water falls in the ocean which may stay there for many years. Some water falls on land & evaporates immediately. Some water runs off into rivers and lakes. Some water trickles down into the ground.

134 QUESTIONS What are the three processes in the water cycle? Answer: evaporation, condensation, precipitation Which process begins the cycle? Answer: a cycle has no beginning and no end. The water cycle is continuous.

135 HOW DO PEOPLE USE WATER?

136 CH ICEBERGS - P. 376 P. 376 in text Titanic movie clip

137 ICEBERGS Titanic movie clip Glaciers move over land and when they hit water they become an iceberg. 10,000 form every year from Greenland. Only about 10 percent of an iceberg is visible. 90% of an iceberg lies below the surface.

138 ICEBERG The underwater part is a hazard to ships because it is often much wider than the visible part of the iceberg. The International Ice Patrol is now set-up to track icebergs.
