What must happen to the agent of erosion (wind or water) in order for deposition to occur?
Gnoma [55]

I am pretty sure that it is D

With decomposition, the final deposition of particles(sediments) usually occurs at the mouth of a stream. Then a process called horizontal sorting occurs where the sediments that were once carried down are arranged from big to small. Decomposition in streams takes time so the speed of the water and wind should not affect it nor should gravity or the direction. Streams cannot change direction either unless human involement occurs

Hope this helps :)
