2.1 Earth's Crust In Motion

Question 0

Deformation

Answer 0

Change in the shape or volume of the crust

Question 1

Strike-slip fault

Answer 1

The rocks on either side of the fault slide past each

Other sideways with little up or down motion

Question 2

What three kinds of stress cause deformation?

Answer 2

Shearing, tension and compression work over millions of years to change the shape and volume of rock.

Question 3

Normal fault

Answer 3

One block of rock lies above the fault while the other block lies below it. The block above the fault is the hanging wall, and the block below the fault is the football. Normal faults are caused by tension.

Question 4

Reverse fault

Answer 4

The hanging wall slides upward past the footwall. Reverse faults are caused by compression.

Question 5

Deformation

Answer 5

The change in shape or volume of the crust

Question 6

Fault-block mountain

Answer 6

When normal faults uplift a block of rock, a fault-block mountain occurs

Question 7

Syncline

Answer 7

A fold that bends downward in the middle to form a bowl

Question 8

Anticline

Answer 8

A fold that bends upward in an arch

Question 9

Plateau

Answer 9

A large are of flat land elevated high above sea level
