Question

Quizplus · Accepted Answer

Mudcracks form in fine-grained sediments that are exposed to air and then dry out, causing the sediment to crack in a characteristic pattern resembling puzzle pieces. Cross beds, bedding, and ripples are sedimentary structures that can form in a variety of sediment types, and cleavage is a type of rock deformation that occurs at greater depths and pressures than most sedimentary environments.
