Question

wind, water, ice and gravity carry sediments away
erosion
weathering*
deposition
cementation

Explanation:

Erosion is the process where natural agents (wind, water, ice, gravity) transport sediments. Weathering breaks down rocks but doesn't move them. Deposition is when sediments are laid down. Cementation is about sediment bonding. The description "Wind, water, ice and gravity carry sediments away" fits erosion.

Answer:

erosion
