Question

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

and that a creek runs through it.
What do their observations tell you about the cave's formation?
A. The cave was formed by deposition of sediments.
B.
The cave produces water from its rock walls.
C.
The cave once was located on the surface of the land.
D. The cave was formed by water wearing away rock.​

Answer 1

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

Step-by-step 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!
