Question

What causes the rock layers of mountains to form zigzag shape?(1 point)
Responses

a transform fault
a transform fault

folding of rock
folding of rock

continental plate uplift
continental plate uplift

a normal fault

Answer 1

The zigzag shape of rock layers in mountains is primarily caused by **folding of rock**. When tectonic plates collide, the intense pressure can cause the rock layers to bend and fold, resulting in the zigzag patterns seen in some mountain ranges.

Answer 2

Use this paragraph: Carlon is using two wooden blocks to model the movement of Earth’s plates. He pushes one block forward and the other block backward, rubbing their surfaces together.

Which Earth feature is he modeling?

Responses

thrust fault
thrust fault

strike-slip fault
strike-slip fault

rift valley
rift valley

normal fault

Answer 3

Carlon is modeling a **strike-slip fault**. In a strike-slip fault, blocks of the Earth's crust slide past each other horizontally, similar to how Carlon is pushing one block forward and the other backward while rubbing their surfaces together.

Answer 4

Use this paragraph: Layla drew a diagram of forces acting on the rock in Earth’s crust. She drew arrows pointing inwards, representing forces pressing on the rock.

Which formation is represented by the diagram?

(1 point)
Responses

a fold mountain
a fold mountain

a transform fault
a transform fault

a rift valley
a rift valley

a mid-ocean rift

Answer 5

The formation represented by Layla's diagram, with arrows pointing inwards to signify forces pressing on the rock, is a **fold mountain**. Fold mountains are formed when tectonic forces compress the Earth's crust, leading to the folding of rock layers.

Answer 6

Which feature is created when a block of rock dropped down in relation to the block of rock beside it?(1 point)
Responses

normal fault produced by tension
normal fault produced by tension

transform fault produced by shear
transform fault produced by shear

reverse fault produced by compression
reverse fault produced by compression

thrust fault produced by compression

Answer 7

The feature created when a block of rock drops down in relation to the block of rock beside it is a **normal fault produced by tension**. In a normal fault, the hanging wall moves down relative to the footwall, typically as a result of extensional forces (tension) acting on the Earth's crust.
