Question

Two Earth scientists are exploring a cave. While moving through the cave, they notice that the caves have smooth limestone walls

Answer 1

Answer:

I think the best answer for this question is D).

Explanation:

This is because the cave has SMOOTH walls, and there is a creek RUNNING THROUGH it. So D) would make the most sense because the creek wore away the sides of the walls, making them smooth.

[If that answer isn't correct, the second best answer would be A].

I hope this helps!
