Calcifiers have less
to
form their shells from.

i am positive it is c. condensing but i may be wrong

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

the answer is 100% density i've answered this question before and done the quiz myself.
