4. All the Water in the World 4 All the water in the world All the FRESH water in the world (3%) All the FRESH water in the world that is not frozen in glaciers or icecaps All the FRESH water in the world that is available for humans and plants to use How much of this represents all the freshwater in the world? How much of this is frozen and inaccessible to humans? How much of this can plants, animals, and humans use?

5. Less than 1% of Earth’s water supply Less than 1% of Earth’s water supply is ready for human use is ready for human use

9. What is the WATER CYCLE? –Water constantly moves among the oceans, the atmosphere, the lithosphere, and the biosphere. This unending circulation of Earth’s water supply is the water cycle. What is the WATER CYCLE? –Water constantly moves among the oceans, the atmosphere, the lithosphere, and the biosphere. This unending circulation of Earth’s water supply is the water cycle. 9

10. The Water Cycle The continuous circulation of Earth’s water supply. Water moves among the oceans, atmosphere, lithosphere and the biosphere The energy source for the water cycle comes from the sun The continuous circulation of Earth’s water supply. Water moves among the oceans, atmosphere, lithosphere and the biosphere The energy source for the water cycle comes from the sun

11. The Water Cycle WC is balanced meaning that the average annual precipitation over Earth EQUALS the amount of water that evaporates. (What goes up comes down) Evaporation exceeds precipitation over water and precipitation exceeds evaporation over land WC is balanced meaning that the average annual precipitation over Earth EQUALS the amount of water that evaporates. (What goes up comes down) Evaporation exceeds precipitation over water and precipitation exceeds evaporation over land

18. What is the law of conservation of matter? The law of conservation of matter says that matter is never created or destroyed. What is the law of conservation of matter? The law of conservation of matter says that matter is never created or destroyed. 18 WATER CYCLE BALANCE

19. How does the law of conservation of matter relate to the water cycle? –Water is never created or destroyed. It just cycles through different forms in what we call the water cycle. How does the law of conservation of matter relate to the water cycle? –Water is never created or destroyed. It just cycles through different forms in what we call the water cycle. 19 WATER CYCLE BALANCE

20. Because water is never created or destroyed, the water cycle is balanced. Balance in the water cycle means that the average annual precipitation over Earth equals the amount of water that evaporates Because water is never created or destroyed, the water cycle is balanced. Balance in the water cycle means that the average annual precipitation over Earth equals the amount of water that evaporates 20 WATER CYCLE BALANCE

21. There are local imbalances –Ex: over the ocean, more water evaporates than precipitates –Ex: over land, more water precipitates than evaporates There are local imbalances –Ex: over the ocean, more water evaporates than precipitates –Ex: over land, more water precipitates than evaporates 21 WATER CYCLE BALANCE

23. FAST FACT 23 The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.

24. What goes up, must come down 24 When it goes up – AGAINST GRAVITY When it goes up – AGAINST GRAVITY

25. 25 When it goes down– WITH GRAVITY When it goes down– WITH GRAVITY What goes up, must come down
