Shadow length increased from sunrise to noon. C. Shadow length decreased from sunrise to noon. D. Shadow length decreased from noon to sunset.

C. Shadow length decreased from sunrise to noon.

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."
