[Q]: Process:  -Water from the ocean washes onto beaches in waves -The waves contain sediment from the ocean -The water and particles in it hit rocks and sand on the beach -The wind and current sometimes push the water and particles harder -Tiny parts of the rocks on the shore come off the larger rocks -The waves pick up sand and small rocks from the beach -The waves go back out into the ocean -The waves carry the new particles with them -Rocks and the beach look a little different.

[Q]: Process:  -Sediment settles in a place due to gravity -The sediment breaks down into small particles -Wind or water picks up the sediment -The sediment travels along the same route as the wind or water -The sediment is deposited at new locations by the wind or water -The sediment is picked up again by new wind or water -The sediment travels further -The sediment is deposited again in a new place.
 Question: What is the effect of sediment is carried by water on sediment is not broken down.?
[A]:
against
