Geo Exam 3 – Chapter 09 Mountain Building

why does rock deform?

• Tectonic forces

• Chemical weathering

• Erosion

• Wind erosion

whats the difference between strain and stress?

• Strain is deformation experienced by a material, while stress is the internal force per unit area applied to it.

• Strain is the internal force per unit area applied to a material, while stress is its deformation.

• Strain and stress are identical concepts.

• Strain is measured in Pascals, while stress is dimensionless.

whats the difference between brittle deformation and ductile deformation?

• Brittle deformation involves cracking with little plastic change, while ductile deformation involves gradual plastic deformation.

• Brittle deformation is slow and time-dependent, while ductile deformation is instantaneous.

• Brittle deformation results in plastic flow, while ductile deformation results in breaking.

• Both deformations exhibit the same behavior.

what controls deformation

• Strain

• Stress

• Force

• Load

what are the characteristics of joints, faults, and folds

• They involve mechanical deformation, displacement, and bending of rocks.

• They are produced by chemical weathering, erosion, and sedimentation.

• They result from volcanic activity and magmatic processes.

• They are exclusively associated with meteorite impacts.

where can we find mountain ranges?

• Along tectonic plate boundaries.

• In deserts.

• In the oceans.

• In the polar regions.

how can we measure mountain ranges?

• Measuring only uplift rates

• Measuring only erosion rates

• Measuring only fault displacements

• Measuring uplift rates, erosion rates, and fault displacements

what is isostasy?

• The principle of gravitational equilibrium of the Earth's crust.

• The process of rock formation in the mantle.

• The movement of tectonic plates.

• The cooling and solidification of magma.

• Africa

• Asia
• North America

• Europe

An episode of mountain building is termed a(n) .

• orogeny
• phylogeny

• aureole
