Wind and rain erosion causes rocks to become dislodged will let it fall or roll to the bottom. Wind and rain erosion do cause rocks to roll to the bottom of a hill but more importantly gravity does. Gravity is the main reason :)
When the ground thaws, the force of gravity causes the soil and rock particles to fall back down. But they fall vertically, toward the center of Earth. The result is movement downhill.
Any time stress causes rocks to change, deformation occurs.
Any time stress causes rocks to change, deformation occurs.
Landslides are caused by the force of gravity pulling on the rocks.
That would be gravity and inertia.
