Frost weathering - Wikipedia

WebbExfoliation is a process in which large flat or curved sheets of rock fracture and are detached from the outcrop due to pressure release: As erosion removes the overburden from a rock that formed at high pressure deep in the Earth´s crust, it allows the rock to expand, thus resulting in cracks and fractures along sheet. Exfoliation the rock breaks … WebbIn temperate climates, water can infiltrate cracks in the sedimentary rocks (and other types as well), and with repeated freeze-thaw cycles, can break the rocks apart by the physical weathering process of frost/ice wedging. The broken rocks often fall down the steep slope to form a pile of rubble at the base of the cliff. optic gaming merch hoodie
