Which of the following is NOT true about mass movement?

• Some mass movement is too slow to be seen.

• Mass movement always leads to landslides.

• Gravity is the driving force behind all mass movements.

• Mass movement is always downslope.

What factor commonly triggers mass movements?

• saturation of surface materials with water

• earthquakes

• removal of vegetation

Why can the removal of vegetation trigger mass movements?

• The soil loses nutrients and begins to crumble.

• The plant roots bind the soil and regolith together.

• The shaking triggers mass movements.

• The plant roots lubricate the loose sediment.
