Chapter 6 Guided Reading Assignment #1 1. Read: 158-163 2. Define the following terms: a) b) c) d) e) Water Cycle Infiltration Transpiration Gradient Stream Channel f) g) h) i) Discharge Tributary Base Level Meander 3. List the five key concepts for this section. 4. Where do we find water? 5. Does water only occur as a liquid on Earth? Explain. 6. What percentage of the Earth’s water is found in the oceans? 7. What is meant by “cycle” when we say “water cycle?” 8. What powers the water cycle? 9. Examine figure 2. List 3 ways water can return to the ocean. 10. Explain why the atmosphere to the water cycle. 11. Explain how infiltration is related to the water cycle. 12. When does rain water flow into streams? 13. How are plants part of the water cycle? 14. Explain what is meant by “Earth’s water cycle is balanced.” 15. How do we know that the water system is balanced? 16. How does gravity influence the way water gets to the oceans? 17. Where in a steam is the velocity of the water the greatest? 18. Why is the velocity of a stream important? 19. Examine figure 3, explain where the velocity of the stream flow the greatest in each diagram and why. CPHS Physical Geology Mr. G. Edelman 20. In the table below, list the three most important factors that determine the velocity of a stream and then list details related to that factor. FACTORS 1. 1. 2. 1. 3. 1. 2. 2. 2. 3. 3. 3. 4. 4. 4. DETAILS 21. Explain what is meant by a stream profile. 22. What is meant by the terms “headwaters” and “mouth” of a stream? 23. Why does a streams discharge increase? 24. Why is the velocity of a stream great downstream in lowlands? 25. What is meant by ultimate base level? 26. What is meant by temporary base level? 27. Examine figures 6 and 7. Explain the flow of the streams in these two situations. Do 1-9 on page 163 “ CPHS Physical Geology Mr. G. Edelman
