th
1. The process by which natural forces move weathered rock and soil from one
place to another is called ______________________.
2. The process of breaking down that material is called
_____________________.
3. The removal of rocks downhill is called ______________________.
4. The most destructive type of mass movement, which is typically due to oversteepening of slopes, is called a _____________________.
5. ________________ are fast-moving downhill movements which are
composed of up to 60% water; they are called “liquefied flows.”
6. A sudden “slip” of soil and rock downhill that goes a very short distanced is
called a __________________.
7. VERY slow movement downhill is called ________________.
8. The amount of sediment that a river is carrying is called its
______________.
9. Small grooves in the soil formed by runoff are called _______________; as
they grow larger, they become ______________.
10. Rivers erode into mountains forming valleys that are ____-shaped.
11. Glaciers later come through those same valleys and change them into
______-shaped valleys.
12. A bend in the course of a river is called a ___________________.
13. When the bend is “abandoned” by the river during a flooding event, the
water left behind is called an ____________.
14. A wide, sloping deposit of sediment that forms where a stream leaves a
mountain range is called an ___________________.
15. Where a river enters the sea, there is a fan-shaped deposit of sediment
called a _____________, named after the Greek letter of similar shape.
16. Water stored in rocks beneath us is called ___________________.
17. A particular body of rock which is a source of water for a given area is
called an ______________.
18. The top of the water reservoir described in Question 17 is called the
__________________.
19. In wet regions where there are limestone deposits, and therefore sinkholes
and caves, we say that there is _____________ topography.
20. In general, as the slope increases, the water speed _________________.
21. As the speed of water increases, the ability to erode ________________.
22. As the speed of water increases, its ability to carry large particles
______________.
23. The deeper and narrower a river channel is, the _____________ the
amount of erosion that takes place.
24. Larger volume tends to correlate with ____________ ability to erode and
carry large particles.
25. A large mass of ice that has movement in a definite direction over land is
called a ______________.
26. Glaciers that cover millions of square kilometers are called
_______________ glaciers.
27. Glaciers that are confined to mountain valleys are called _____________
glaciers.
28. The process in which small and large rocks are picked up from the earth and
incorporated into the base of the glacier is called _________________.
29. Glacial sediment, which is generally a mix of very poorly sorted sediments, is
called _____________.
30. When glaciers carve away at all sides of a mountain, leaving a sharpened
peak in the center, it is called a ______________.
31. A bowl-shaped hollow that has been eroded into the upper side of a
mountain by a glacier is called a _______________.
32. A sharp ridge created when two glaciers erode back-to-back is called an
_____________.
33. A deep inlet of the sea formed by glaciers is called a ______________.
34. A mound or ridge of poorly sorted rock debris that is “plowed up” by a
glacier along its front or sides is called a _______________.
35. Tear-drop shaped mounds of till are called __________________.
36. Large rocks stranded by melting glaciers are called __________________.
37. A portion of the shoreline that juts outward into the ocean and receives
most of the energy of incoming waves is called a _________________.
38. Hollows carved out of a sea cliff by waves are called _______________.
39. When two of the features described in question 38 erode back-to-back,
they form a ________________.
40. Sediment that accumulates where the ocean meets land forms a
_______________.
41. Sediment on a beach is moved constantly by a process called
__________________; it forms as the incoming wave, or _________,
comes in at an angle and the outgoing wave, or _________________, goes
out perpendicular to the shoreline.
42. A beach that projects like a finger out into the sea is called a
___________.
43. An island that forms offshore, parallel to the beach, and is above sea level
is called a ___________________.
44. The process by which wind removes surface materials, leaving larger
particles behind, is called ___________________.
45. Extremely fine-grained, wind-blown sediment that is deposited across large
areas of land is called ___________________.
