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!!
