3. A _______ involves a rotational movement of rock or regolith. o D) slump
4. Glacial ______________ are usually multiple, straight, and parallel, representing the movement of the glacier using small rocks and pebbles, embedded in the base of the glacier, as cutting tools. o C) striations
5. Small boulders carried along underneath the glacier provide the abrasive power to cut trough-like glacial ________________. o A) grooves
6. ____________ is the set of processes that breaks down the rock in place, no movement is involved. o B) weathering

8. __________________ is simply movement down slope due to gravity.

o D) mass wasting
9. ___________________________ involves a chemical change in at least some of the minerals within a rock during its break down. o B) chemical weathering
10. ___________________________ involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it. o A) mechanical weathering
11. _______________ is the breakdown of the rock in place (in situ o B) Weathering
12. _______________ is the transportation of this loose material mainly by water, but also by wind (Aeolian), ice and gravity. o A) Erosion

16. ____________ is an example of mechanical weathering produced by the freezing and thawing of water. o B) Frost wedging

17. ________________ - Organic matter (The uppermost horizon in many soil profiles.) o C) O Horizon
18. ________________ - Dark-colored layer of mixed mineral and organic matter
(typically dark in color because of the humus present) o B) A Horizon
19. ________________ - Light-colored layer marked by removal of soluble material ( typically grayish in color because it contains little humus, more common in acidic soils of evergreen forests). o A) E Horizon
20. ________________ - Maximum accumulation of clay minerals (Brownish or reddish in color because of the presence of iron hydroxides from transported horizons above. o E) B Horizon
21. ________________ - Weathered parent rock. o D) C Horizon
22. Suspended load is sediment that is moved along the bottom of a stream, mainly boulder cobbles and pebbles are pushed by the water. o FALSE
23. The sand grains are also pushed along the bottom of a river by a process called saltation (jumping). o TRUE
24. Bedload is the sediment that is carried in suspension by a flowing stream of water, the sediment here is mainly silt and clay. o FALSE

25. Dissolved load - soluble materials that are carried on top of the stream along with floating organic matter. o FALSE
