1 .		Whenever bedrock is exposed, it weathers.   True  False
2 .		The most common structural features of the rocks of the lithosphere are faults.   True  False
3 .		Solution cavities are holes formed in calcareous rocks as the soluble minerals are dissolved and carried away by percolating water.   True  False
4 .		From a chemical standpoint, oxygen, carbon dioxide, and water vapor are the three atmospheric components of greatest importance in rock weathering.   True  False
5 .		Mechanical weathering is the physical disintegration of rock material without any change in its chemical composition.   True  False
6 .		The frequent alternation of freezing and thawing is called frost shattering or frost wedging.   True  False
7 .		Salt wedging occurs when salts crystallize out of solution as water evaporates.   True  False
8 .		Chemical processes operate more rapidly in dry climates than in humid climates.   True  False
9 .		In cold lands the influence of mechanical weathering is dominant.   True  False
10 .		Hydrolysis is the chemical union of water with another substance to produce a new compound.   True  False
11 .		The penetration of growing plant roots into cracks and crevices is known as mechnical weathering.   True  False
12 .		Mass wasting is the process whereby weathered material is moved a relatively short distance downslope under the direct influence of gravity.   True  False
13 .		Talus are the fragments that fall around the base of a rock.   True  False
14 .		A landslide is an instantaneous collapse of a slope with plastic flow.   True  False
15 .		Slumping involves slope collapse in which the rock or regolith moves downward and at the same time rotates outward along a curved surface that has its concave side facing upward.   True  False
