One ways animals can increase erosion in an area is by_____________. Select all that apply.
Eating and removing vegetation.
Creating an environment with reduced wind and water.
Creating walking paths and exposing the soil.
Digging burrows that weaken the ground.
_____________ are mass movements that involve the sediments moving as one large mass.

Can lead to improved construction sites
Can increase the water table making ground water more accessible.
Plants can act as _____________ which __________ in the area.
Excavators, increase deposition.
Wind Barriers, increase erosion.
Anchors, reduce erosion.
Wind Barriers, reduce deposition.
One thing humans can do to manage mass movements in an area is...

Increase the slope in an area.
redirect water away from the area.
decrease the vegetation in the area.
