Explanation / Answer

earthquakes shaking ocean waves heavy rain tend to destabilise slope. when a mass movement of slope occur then it becomes unstable.

the columbia plateau is an example of rain shadow desert. (The Columbia Plateau, also called the Columbia Basin, has a semi-arid climate, with a near-desert climate in the lowest sections of the basin. This is largely due to the rain shadow cast by the Cascade Mountains)

slab pull , gravitational sliding are driving forces.

the void space in the sandstone is primary porosity. which exists as space between detrital grains
