-------------is the movement of weathered materials under the force of gravity
Answer Details
Mass movement is the movement of weathered materials under the force of gravity. This refers to the downhill movement of soil, rock, or other materials due to gravity. Mass movement can take different forms, including landslides, mudflows, and rockfalls. It occurs because the materials become loosened and unstable due to weathering processes, such as freeze-thaw cycles or the action of water. The force of gravity then causes the materials to move downslope. Mass movement can have significant impacts on people and the environment, as it can cause damage to structures, disrupt transportation routes, and alter the landscape.
