What does the theory of uniformitarianism state?

A. Evidence from fossils can give us glimpses into the past.

B. Major catastrophic events shaped the earth.

C. Geologic processes we see today were also at work in the past

D. Earth has not changed for billions of years.

C. Geologic processes we see today were also at work in the past

Option (C)

Explanation:

In the field of geology, a geologist James Hutton introduced the theory of Uniformitarianism. According to this theory, it means that the earth undergoes a variety of geological process that takes place over a long period of time and is responsible for the different types of changes that occurs on earth. All these processes that occur now must have occurred in the past too with the same intensity that has caused a tremendous effect on the earth. it is also believed that the same processes will also take place in the present, maintaining uniformity.

Thus, the correct answer is option (C).
