Due to fluctuation of weather 5 of 11 Exfoliation/Onion skin weathering When outer skin of rock appears to flake due to large fluctuations in temperature and repeated expansion and contraction 6 of 11 Mass movement The downhill movement of material under the influence of gravity 7 of 11 Rockfall the collapse of a cliff face or the fall of individual rocksfrom a cliff usually due to freeze thaw 8 of 11 Landslide When blocks of rock slide downhill 9 of 11 Mudflow saturated soil and weak rock flows down a slope 10 of 11 Rotational slip Slump of saturated soil and weak rock along a curved surface 11 of 11
