Sixth Grade Chapter 9 Review: Erosion and Deposition
1. What is erosion? PROCESS BY WHICH NATURAL FORCES MOVE WEATHERED ROCK & SOIL
2. What is mass movement? PROCESSES THAT MOVE SEDIMENT DOWNHILL
3. Describe four examples of mass movement. (Creep, mudflow, landslide, and slump.)CREEP-SLOW DOWNHILL MOVEMENT OF ROCK & SOIL; MUDFLOW- RAPID DOWNHILL MOVEMENT OF WATER, ROCK, & SOIL; LANDSLIDE- ROCK & SOIL SLIDE QUICKLY DOWN A STEEP SLOPE
4. What is a tributary? A STREAM OR RIVER THAT RUNS INTO ANOTHER STREAM OR RIVER
5. What are meanders? LOOP-LIKE BEDS IN RIVER
6. How does a waterfall form? SOFTER ROCK IS WORN AWAY LEVING BEHIND HARD ROCK
7. What is an alluvial fan? A WIDE SLOPING DEPOSIT OF SEDIMENT WHERE A STREAM LEAVES A MOUNTAIN RANGE
8. Deltas are built up by DEPOSITION.
9. What causes most sediment to wash or fall into a river? MASS MOVEMENT & RUNOFF
10. As more water flows into a river, what happens to the speed of the river? IT INCREASES
11. What is one main difference between continental and valley glaciers? CONTINENTAL GLACIERS ARE THICKER
12. When can glaciers form? WHEN MORE SNOW FAL THAN MELTS
13. What is the process of plucking? ROCK FRAGMENTS FREEZE TO BOTTOM OF GLACIER & ARE CARRIED AWAY
14. When does wind deposit sand? WHEN IT SLOWS DOWN OR HITS AN OBSTACLE
15. What is loess? PARTICLES OF CLAY & SILT THAT WERE ERODED & DEPOSITED BY THE WIND
16. What are agents of erosion? WIND & WATER
17. What is the force that moves sediment in a landslide or mudslide? GRAVITY
18. What is a slump? SEDIMENT SUDDENLY SLIPPING DOWNHILL IN A LARGE MAS
19. What is the major agent of erosion? MOVING WATER
20. What are flood plains and how are they formed? FLAT AREAS COVERED BY WATER DURING FLOODS; FORMED BY EROSION
21. What is a delta? SEDIMENT DEPOSITED WHERE A RIVER FLOWS INTO THE OCEAN
22. AS the water in a river moves downstream, what type of energy of the water moves the sediment? KINETIC ENERGY
23. What are the main ways that sediment enters a river? MASS MOVEMENT & RUNOFF
24. When and how does a valley glacier form? WHEN ICE & SNOW BUILD UP IN A RIVER VALLEY
25. What are the ice ages? TIME WHEN CONTINENTAL GLACIERS COVERED MOST OF EARTH’S SURFACES
26. What are the two processes in which waves erode the land? ABRASION & IMPACT
27. What is plucking? PROCESS WHERE GLACIER LOOSENS & PICKS UP ROCKS AS IT MOVES
28. What is a tributary? A STREAM OR RIVER THAT FLOWS INOT ANOTHER STREAM OR RIVER. Be able to recognize a tributary in a diagram.
29. How does a delta form? FORMS WHEN A RIVER SLOWS DOWN AS IT FLOWS INOT AN OCEAN OR LAKE & DROPS ITS SEDIMENT LOAD. Be able to recognize it on a diagram.
30. How does a meander form? FORMED WHEN A RIVER ERODES THE OUTERBANK ALONG BEND & DEPOSITS SEDIMENT ON THE INNER BANK OF THE BEND. Be able to recognize it on a diagram.
31. How does an oxbow lake form? AN OXBOW LAKE THAT HAS BEEN CUTOFF FROM THE MAIN STREAM OF THE RIVER. AFTER FLOODWATERS FALL, SEDIMENTS DAM UP BOTH ENDS OF A MEANDER LEAVING AN OXBOW LAKE. Be able to recognize it on a diagram.
32. How does a waterfall form? HARDER ROCK OVERLAYS SOFTER ROCK. SOFTER ROCK IS ERODED AWAY CAUSING HARDER ROCK TO BREAK OFF CREATING THE WATERFALLS STEEP DROP. Be able to recognize it on a diagram.
33. In paragraph form: Compare and contrast mudflows and landslides.
