Caves are formed from: freezing water sedimentation mechanical weathering chemical weathering

Caves are formed by a type of chemical weather called carbonation.

The answer is d. chemical weathering.

the answer here is D. Chemical weathering

:)

Reason:

Freezing water doesn't make sense...at all

sedimentation is "the process of settling or being deposited as a sediment."

mechanical weathering is "Mechanical weathering is the process through which large rocks are broken into increasingly smaller pieces. ... It involves mechanical processes that disintegrate a rock, like tree roots growing in cracks in a rock and eventually breaking it up. Mechanical weathering doesn't change the chemical nature of the rocks."

sry that one was long... :)

and chemical weathering is: "the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions"

hope this healps and i hope you have a nice day!!
