Rocks on either side of a strike-slip fault move past each other without much upward or downward movement is

strike-slip fault

Explanation:

A fault is a crack on the crust of the Earth where forces on the rocks causes the displacement of the rocks.

The movement of the crust determines the type of fault.

When rocks slip pass horizontally with respect to each other then it is called a strike slip fault. The crust moves towards each other causing horizontal compression. The displacement of the rock takes place parallel to the horizontal force.

Hence, the statement here is referring to the strike-slip fault.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
