Question 1

denudation

Answer 1

overall effect of of the disintegration, wearing away, and removal of rock material

Question 2

weathering

Answer 2

breaking down of rock into smaller components by atmospheric and biotic action agents

Question 3

mass wasting

Answer 3

relatively short-distance downslope movement of broken rock material under the direct influence of gravity

Question 4

erosion

Answer 4

removal, transportation, and eventual deposition of fragmented rock material over wider areas and sometimes to greater distances that is the case in mass wasting

Question 5

mechanical v chemical weathering

Answer 5

physical disintegration of rock material without any change in its chemical composition. decomposition of rock by the chemical alteration of its minerals, requires moisture

Question 6

mechanical

Answer 6

frost wedging, salt wedging, temp changes

Question 7

exfoliation

Answer 7

curved layers peel off of bedrock. peeling away of very thin rock weathering layers

Question 8

chemical

Answer 8

oxidation-rusting, hydrolysis-, carbonation

Question 9

biological weathering

Answer 9

plants and animals contribution to weather, growing plant roots

Question 10

types of mass wasting

Answer 10

rockfall, lanslide, slump, flow, creep,
