You are possibly referring to a Landslide? Depending on if you are talking about land waste; and by that I mean waste quite like till, or of rock mass. If rock mass is the answer to that you could be meaning weathering (truthfully i do not know if that is the correct spelling though).
This is broadly known as mass wasting which is a type of erosion.
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.
erosion
Erosion is the moving of weathered material and sediments from one place to another place by wind, water, ice, and gravity.
Slow- moving downslope movement of water- saturated, clay- rich sediment, most characteristic of humid regions.

material moving downslope as a thick fluid
Material moving down a slope, depending upon the kind of material involved, could be described as falling, rolling, sliding, or slumping.
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.

The reason that Earth travels around the sun is because of gravity. The Gravity of the sun pulls all the planets towards it. This gravity will pull all material that is not moving into it, and material that is currently moving will be pulled into an orbit. The shape of the orbit depends on the original speed of the object.
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.

cooler particles are slower moving thus more dense. the more dense the material the further it will sink
what type of material is not moving in the rock cycle
Magnetic forces can be caused by an electric current. Or they can be caused bymagnetic domains aligned correctly. These domains are magnetic moments created by moving atoms in the material who have an electric dipole (usually).
