Question - Essay Example Yes water affects mass wasting processes. Water reduces adhesive forces been the soil among other debris materials thereby facilitating mass wasting. Additionally, water often has force large enough to move material including large debris down the stream. The downward movement of loose and unconsolidated materials including soil and sediment is often due to force of gravity. At the point where the soil among other consolidated materials is not moving down the hill, such material are held in place with frictional force. The point at which the gravitational and frictional force balances is referred to angle of repose. This is the maximum angle that a friction force can hold loose material on the surface of the earth not to move downhill. Therefore, angles greater than angle of repose usually lead to mass wasting and at this point the force of gravity is slightly greater than frictional force holding the same materials. Soil creeping is a long term mass wasting process and it combine the movement of small and rocky materials in undirected direction. The movement of such materials are often facilitated by force of gravity. The creep usually do much damage since it leads to collection of materials over time especially behind trees; thus, it may lead to landslides triggered mainly by these tree particularly in cases that they lose root
