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?

A. thrust fault

B. strike-slip fault

C. normal fault

D. rift valley

B. strike-slip fault

Carlon is using two wooden blocks to model the movement of Earth's plates. Specifically, he pushes one block forward and the other block backward, rubbing their surfaces together. Based on this description, Carlon is modeling the movement of Earth's plates known as a strike-slip fault. Therefore, the correct answer is B. strike-slip fault.

A. a fold mountain

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?

A. a fold mountain

B. a mid-ocean rift

C. a rift valley

D. a transform fault

To determine which Earth feature Carlon is modeling, we need to understand the different types of faults and Earth features mentioned in the paragraph.

A. Thrust fault: A thrust fault occurs when one rock mass is pushed over another rock mass in a horizontal direction. This is not described in the given paragraph.

B. Strike-slip fault: A strike-slip fault occurs when two blocks of rock slide past each other horizontally. This is also not described in the paragraph, as Carlon is not sliding the blocks past each other horizontally.

C. Normal fault: A normal fault occurs when two blocks of rock are pulled apart, with one block moving downward relative to the other. This is not what Carlon is modeling in the given paragraph.

D. Rift valley: A rift valley is formed by the stretching and pulling apart of Earth's crust, resulting in a long, narrow depression. The paragraph does not mention the stretching or pulling apart of the blocks, which is characteristic of a rift valley.

Therefore, based on the information given in the paragraph, none of the options (A, B, C, or D) accurately represent the Earth feature that Carlon is modeling.
