You notice preserved ripple marks in the mountains, then later at the beach you see ripple marks forming in the sand. Which of the following best describes how the ripple marks in the mountain formed?

uniformitarianism

stratigraphic correlation

catastrophism

deformation

Option (A)

Explanation:

The law of uniformitarianism describes how ripple marks were formed in the mountains.

This law says that the geological processes that occur extensively over the surface of the earth and configures the earth's surface in the present, have occurred in the past too and will also continue in the future.

This law simply describes that the present is the key to the past. This means that the processes that occur now must have taken place of the past.

In the given condition, this best describes the formation of ripples in the mountains.

Thus, the correct answer is option (A).
