deformation quiz

Question 0

Answer 0

The bending, tilting, and breaking of the earth’s crust; the change in the shape of rock in response to stress.

Question 1

What is stress?

Answer 1

The amount of force per unit area on a given material. ( push and pull, force, and the amount of pressure on the earth)

Question 2

Describe 3 types of stress.

Answer 2

Compression: when an object is squeezed ( convergent boundary )
Tension: when forces act to stretch an object ( divergent boundary)
Shearing: the crust is getting pushed in opposite directions ( transform boundary)

Question 4

What is a folding rock?

Answer 4

Bending rock

Question 5

What factors would cause a rock to fault or fold? Be specific.

Answer 5

Folding: higher temperatures and pressure, ductile ( bendable) rock, and pressure applied gradually to a rock.

Faulting: lower temperatures and pressure, brittle rock, and pressure applied fast to a rock.
