Transcript

  • 1. Water erosion<br />Chapter 10<br />
  • 2.
  • 3. 1. Water cycle-<br />Each part of the<br /> cycle drives <br />the other parts. <br />
  • 4. A.____________- water changing to water vapor<br />evaporation<br />
  • 5. A. ____________________ - evaporation from ice;<br />sublimation<br />
  • 6. A. __________<br />Evaporation <br /> from plants<br />transpiration<br />
  • 7. condensation<br /> _ -changing water vapor<br /> into liquid form<br />
  • 8. precipitation<br />C. ___________- liquid or solid form of <br />water falling to Earth<br />
  • 9. 2. ______________- a network of rills, gullies, which join to form rivers<br />River system<br />
  • 10. runoff<br />3.________-rainwater that does notsoak into the ground or evaporate<br />
  • 11. 4. Factors that influence runoff:<br />A. type of land<br />B. slope<br />C. amount of rain<br />D. time span in which rain falls<br />E. amount of vegetation<br />F. climate/temperature<br />
  • 12. 5. __________- a stream or river that flows into a larger river<br />tributary<br />
  • 13. 6. ____________- also called a______________ the LAND that supplies water to a river system; the land from which a river collects __________<br />watershed<br />drainage basin<br />runoff<br />
  • 14. Largest watershed in the US- Mississippi<br />
  • 15.
  • 16. 7. Water Erosion Features<br />
  • 17. rill and gully erosion<br /> small streams<br />form and erode a groove into the <br /> land; if it continues a gully will form.<br />(channel)<br />
  • 18. stream erosion<br />B. ____________ -water continually erodes the same path making a__________<br />and ___________ river<br />deeper<br />wider<br />
  • 19. floodplain<br />C.___________ fertile area covered by <br />sediment caused by frequent flooding<br />
  • 20. meander<br />D. __________- When a river or stream begins to curve back and forth<br />
  • 21. Meandering<br />
  • 22. oxbow lake<br />___________a piece of a meander that has <br />been cut off from the main river<br />
  • 23.
  • 24. F. _____________- wide, sloping deposit of sediment formed where a stream leaves a mountain range<br />alluvial fan<br />
  • 25. delta<br />fan<br />G.______sediments dropped in a _____ <br />shape at the mouth of a river<br />
  • 26. levee<br />H.________an earthen barrier built along <br />a river<br />
  • 27. groundwater<br />8. ____________water that sinks (leaches) <br />into the porous parts of Earth’s crust <br />(about 90% of all fresh water)<br />
  • 28. 9. ______- a ridge of land that separates watersheds<br />divide<br />
  • 29. pond<br />10. ______- a small body of still fresh water<br />
  • 30. 11. ________- the place where an organism lives and <br /> obtains all the<br /> things needed<br /> to survive<br />habitat<br />
  • 31. 12. ________-a lake (manmade or natural) that stores water for human use<br />reservoir<br />
  • 32. wetlands<br />13. _________- land covered with water all or part of the year (marshes, swamps, or bogs)<br />
  • 33. 14. ________- where mouth of a river opens to the ocean; fresh and salt water mix<br />estuary<br />Not as salty<br /> Nutrientrich<br />Important habitat<br />
  • 34. Why is an estuary like a…<br />Sponge? An estuary soaks up water. As excess rains flood rivers and streams, wetlands form to absorb water that may otherwise flood dry living areas needed by both animals and people.<br />Hotel? As birds migrate hundreds and thousands of miles across North America, they stop in marshes and estuaries to eat and rest before continuing on their journey. <br />Egg beater? A coastal wetland is a place for nutrient-rich freshwater from a river or stream to mix with saltwater from the bays. As plants photosynthesize, oxygen is added to the mix. Fishes and shellfish take advantage of this life-giving soup. <br />Cradle? An estuary provides a protective haven for young animals: plenty of food and places to hide from predators. Sea grasses and other vegetation give cover. <br />
  • 35. Strainer? The grasses of an estuary act like a sieve. Soil, branches, leaves, and even trash that has washed into the estuary are strained. This allows cleaner water to pass on downstream and into the Gulf of Mexico.<br />Cereal? Plants absorb nutrients and help cycle them through the food web. As the grasses of the estuaries decay, or rot, a nutritious food for animals and fertilizer for other plant life are supplied.<br />Soap? Estuaries trap, neutralize, and decompose sewage and other wastes. Excess nutrients and chemical toxins are absorbed as well. Through chemical reactions and processing by plants, water is cleaned before it passes downstream. <br />
  • 36. permeability<br />low<br />15. ___________ rockswith a _______ <br />density; many spaces<br />
  • 37. impermeability<br />16.________________rocks with a ____ density; tightly packed <br />high<br />
  • 38. water table<br />17. _____________- upper surface of the <br />zone of saturation <br />
  • 39. Zone of saturation<br />_________________ -area where water fills <br />up a permeable layer.<br />
  • 40. Zone of aeration<br />B. ___________________- area of crust filled with air<br />
  • 41. 18. __________ underground layer of rock or sediment that holds water<br />aquifer<br />
  • 42.
  • 43. spring<br />19._____________- where the water table is close to the Earth’s surface, water may ooze out to form a spring; ____________- form when groundwater comes in contact with hot underground rocks.<br />hot springs<br />
  • 44. 20. ___________ - water under pressure <br />raises to the surface because of the <br />abundance of water in an aquifer. <br />artesian well<br />
  • 45. permeable<br />impermeable<br />
  • 46. geysers<br />21. ________- hot springs that are forced upward through a small opening<br />
  • 47. The End<br />
  • 48. young stream<br />A. ___________ moves _______, may have white water rapids and waterfalls; high level of energy; erodes ________ <br />swiftly<br />bottom<br />sides<br />faster than the ______<br />
  • 49. ___________________flows less swiftly; <br />erodes waterfall rocks away; more <br />gentle gradient; begins to _____________ <br />(curve back and forth)<br /> mature stream<br />meander<br />
  • 50. old stream<br />C. __________flows slowly through a <br />floodplain; has ______ meanders<br />wide<br />
