The video series would contain GC Leong and Physical geography class 11th books explanation in a very simplified format:

Summary :
Mass Movements: Transfer the mass of rock under the direct influence of gravity. Movements may be slow or rapid. Air, water and other agents do not play a role, its just gravity.
Weathering is not a prerequisite for mass movements though it aids mass movements.
Mass movements do not come under erosion.
Gravity is greater than Resistance b/w rocks.
Causes = Gradient increase, Overloading, Lubrication of supportdue to rainfall, removal of material or load, Earthquakes, excessiveNatural seepage, removal of natural vegetation.
Heave: soil breakage due to upward swelling of soil during freezing conditions caused by increasing presence of ice as it grows towards surface.
Slow movements : Soil Creep – gradual but more or less continuous movement of soil downmoderately steep soil covered hill slopes. Common in damp soils where water acts as a lubricant.
Solifuction: Slow flowing soil mass or fine grained rock debris downslope saturated or lubricated with water. Common in moist temperate areas where surface melting of deeply frozen ground & longcontinued rain occur frequently. Soil acts like a liquid. In Ireland such flows are called bog – bursts.
Rapid movements : Humid conditions . Gentle to steep slopes
Earthflow: Movement of water saturated clayey or silty earth materials downLow angle terraces or hill sides.
Mudflow : Caused by Vegetation cover scarcity, Heavy rainfall, Thick layers of weathered materials get saturated with water flow downwards either slowly or rapidly.
Debris Avalanche : Steep slopes , faster than mudflow, Similar to snow avalanche
