<span>I'm not sure I
completely understand what the question is asking for. When I look at
the plates, it looks like they all fit together like a giant puzzle.
They separated due to tectonic plates shifting over hundreds of years.
This was based on the theory that there was a supercontinent (one giant
landmass). I'm not sure how much this helps, but I hope it does. Good
luck!!

Answer:
D) uniformitarianism; the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today
Explanation:
When geologists conclude that the Grand Canyon sequence of rocks was formed through hundreds of millions of years of deposition, mountain building, and erosion, they are basing this conclusion on the principle of <u>uniformitarianism </u>which states that <u>the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today</u>.
Uniformitarianism is a theory in geology which states that the changes in the earth's crust during geological history is as a result of actions of uniform and continuous processes, that the geological processes occurring currently are same processes that have been occurring in history and every part of the world and is continuous.
