Classification of Mass Movement (Leaving Cert Geography): Flashcards

Gravity causes downhill movement of rock, soil, and debris.

Creep is the slow movement of soil and regolith downhill.

Slow movement due to gravity and freeze-thaw cycles.

Gravity, saturation from rain, and seismic activity.

Heavy rainfall, earthquakes, or steep slopes trigger slides.

Material flows like a fluid down a slope, often saturated.

Mudflows, debris flows, and lahars are common flow types.

Saturation from heavy rain or volcanic activity.

Types include falls, slides, slumps, and flows.

Loose debris drops suddenly due to gravity on steep slopes.
