There are four main natural agents (causes) of
erosion. Name 3 of them.
41
You must have 3 of the following1. water
(rainfall and rivers can carry sediment to other
places)2. wind (wind can pick up and move
small rock material)3. ice or glaciers
(glaciers slowly move the sediment on the ocean
floor)4. gravity (gravity can cause mass
movement)
