A

47
Q

is the resistance to flow (an antonym for fluidity).

A

Viscosity

48
Q

Deep in the Earth, nearly all magmas contain gas dissolved in the liquid, As magma rises at the surface of the Earth, pressure is decreased and the gas forms a separate vapor phase. This is somewhat similar to carbonated beverages which are bottled at high pressure.

A

49
Q

this hot material rises to an area of lower pressure through convection. the process of

A

Decompression Melting

50
Q

Happens when hot, liquid rock intrudes into the Earth’s crust. As the liquid rock solidifies, it loses this heat and transfers it to the surrounding crust. This is similar to a hot fudge poured over cold ice cream.

A

Mafic Magma

56
Q

The hottest and fastest flowing magma.

A

Ultramafic Magma

57
Q

Rocks buried deep within the Earth’s crust behave differently when subjected to differential stress. It is impossible to produce fracture in rocks the way it is at the Earth’s surface. Rocks become thicker under compressional stress and thinner under tensional stress. Rock layers tend to bend and go out of shape. The high temperature condition makes a rock softer, less brittle and more ductile.

A

Deformation

58
Q

For small differential stresses, less than the yield strength, rock deforms like a spring. It changes in shape by a very small amount in response to the stress. The deformation is not permanent. This deformation is reversable. The rock can return to its original shape.

A

Elastic deformation

59
Q

Near the Earth’s surface rock behave in its familiar brittle fashion. If a differential stress is applied that is greater than the rock’s yield strength, the rock fractures. Fracture is an is an irreversable strain wherein the rock breaks.

A

Brittle deformation or Fracture

60
Q

the force that could create deformation on rocks in their shape and/ volume.
Great forces from several directions may act on the lithospheric plates causing them to move. Although this crustal plates are elastic solid, they are subjected to great forces such as pulling, pushing or squeezing.

A

Stress

61
Q

ability of a rock material to handle stress depends on the elasticity of the rock.

A

Strain

62
Q

fractures in rocks that show little or no movement at all.

A

Joints

63
Q

This is when rock is stretched apart or pulled apart. Where crustal plates diverge, rocks are pulled apart

A

Tensional stress (stretching).

64
Q

This is when rock is pressed, squeezed or pushed together. It’s like a car caught in the middle of a long pile up on the highway. Where crustal plates collide, rocks are compressed or pushed

A

Compressional stress

65
Q

which results in slippage and translation. The rock is being pulled in opposite directions. It is similar to the motion between individual playing cards when the top of the stack is moved relative to the bottom

A

Shear stress

66
Q

Rock beneath the Earth’s surface experiences equal pressure exerted on it from all directions because the weight of the overlying rock.
It is like the hydrostatic stress (water pressure) that a person feels pressing all over his body when diving down deep in the water.

A

Lithostatic stress

67
Q

stress on rocks that are caused by an additional due to unequal stress due to tectonic forces.

a result of continuous pulling and pushing.

A

Faults

70
Q

Types of Faults

A

a) Dip-slip fault (Normal fault)
b) Strike-slip fault
c) Reverse (or thrust) fault

71
Q

occurs when brittle rocks are stretched-tectonic tensional forces are involved and the movement of blocks or rock is mainly in the vertical direction (sinking and rising).

A

Dip-slip fault (Normal fault)

72
Q

occurs when brittle rocks are sheared (the opposing tectonic forces are at right angles to compression and tension directions) and the movement of blocks of rock is chiefly in the horizontal direction.
If the far side of the fault moves to the left relative to an observer it is called “sinistral strike- slip fault” (left-lateral).

A

Strike-slip fault

73
Q

occur when brittle rocks are pushed (the tectonic forces are compressional).

A

Reverse (or thrust) fault

74
Q

promoted by high temperature and pressure at great depth.
When rocks deform in a ductile manner, instead of fracturing to form faults or joints, they may bend or fold and the resulting structures

A

FOLDS

75
Q

are the simplest types of folds, occur when the horizontal layers are bent upward so that two limbs of the fold are still horizontal.

A

Monoclines

76
Q

are folds structures when the original rock layers have been folded downward and the two limbs of the fold dip inward toward the hinge of the fold.
