Answer:
The correct answer to the question: A naturally occurring principle that aids in the weathering process is:____, would be, C: Gravity.
Step-by-step explanation:
The first reason for this being the answer is that the question asks for a naturally occurring principle, and from the options given, only gravity is a natural occurring event and a principle. Pollution is man-made, therefore not naturally occurring and not a principle either. Neither is plastic decomposition as this is a process, not a naturally occurring principle. Expansion of civilization is neither natural, nor is it a principle and it definitely has nothing to do with weathering. However, gravity plays a role in all the processes that happen on Earth, because this force is responsible for the way that elements that do play a role in weathering, act.
