contraction

32
Q

unloading of minerals on surface

A

exfoliating

33
Q

occurs when water filling a crack freezes and expands

A

frost wedging (ice)

34
Q

formed of till, one end is steep while the other tapers away to ground level, can form near the margin of glacial systems and within zones of fast flow deep within the ice sheet, record the ice movement at the time of formation

A

Drumlim

35
Q

reacts with water

A

hydrolysis

36
Q

water combines with compounds in rocks, causing a chemical change in a mineral’s structure

A

hydration

37
Q

pH of rainwater

A

5.7

38
Q

chemical responsible for dissolving limestone that is precipitated in subsurface soil

A

acidification

39
Q

form of acidification attached to the ceiling

A

stalactites

40
Q

form of acidification that rises from floor

A

stalagmites

41
Q

When carbon dioxide is released from evaporating water

A

carbon dioxide goes into air, and limestone is deposited, water flow determines thickness of stalactite

42
Q

In chemical weathering: the loss of an electron is

A

oxidation (makes minerals unstable)

43
Q

driven by gravity as tumbling, flowing, or creeping of material down steep slopes and make land forms such as landslides

A

Colluvial processes

44
Q

When gravitational stresses exceed the strength of rock or soil, slope failure occurs, also known as

A

landslides

45
Q

46
Q

streams carry sediment to glacial lakes with the melting of glacier, building ________ on top of the ice

A

kame deltas (kames)

47
Q

can form near the margin of glacial systems and within zones of fast flow deep within the ice sheet, record the ice movement at the time of formation

A

Drumlim
