What does the principle of uniformitarianism state? a. geologic processes taking place on the earth today operated similarly in the past and can be used to explain past geologic events. b. sedimentary rocks are deposited in approximately horizontal layers; if they are not horizontal, they have been rerranged by the action of forces within the earth. c. younger rocks are deposited on top of older rocks in undisturbed sedimentary rock laters. d. specific groups of organisms have followed, or succeeded, one another in a definite sequence trhough earth's history.

Your  Geologic processes taking place on the Earth today operated similarly in the past and can be used to explain past geologic events.

When answering this question, we're practically going to find what the word "uniformitarianism" actually means in this case. This would all revolt around the theory based on the (geological history), the fact that they believed in the changes of how the earth's crust were to changed during in different phases.

One thing that we would also have to consider would be the fact that this would have to have uniform, and not just the fact that it would be a mal-disorganized change of the earth's crust.

Based on you'r option, we would see how this would be able to be our answer in this case. This would be the process of the Geologic that would take place on the earth, and also, the explanation would be clear above how this would all relate.

The answer is in my the answer is 15.6
