Question

Scientist observe several strata that are tilted at an angle what most likely caused the tilting

Answer 1

Answer:

Option C, The strata were moved after they were deposited

Explanation:

Options for the question are -

A The strata were deposited at an angle.

B Fossils were deposited within each stratum.

C The strata were moved after they were deposited.

D The strata were deposited in a small area.

Solution

Sedimentary rock layers are known as strata. Each stratum is a distinctive layer that deposits one over the other in a manner that the oldest layer lays at the bottom while the youngest layer deposits at the top. Generally these strata’s are laid down horizontally. Hence the layers which appear to be tilted have tilted after deposition only. Likewise any other change in strata is terms of its position or structure generally takes place after the deposition of that layer.  

Thus, option C is correct
