D: Sand along a shoreline is repeatedly picked up by waves.
Explanation:
C. Running water cuts small channels into a slope describes rill erosion.
Rill erosion occurs when concentrated water creates little channels as it moves down the slopes. The moving water downhill plays an important role as medium of transporting sediments. Rill erosion occurs where there has been a great disturbance of soil in uplands areas.
The depth of the channels may be a few centimeter deep or less while along the channel slopes they tend to be deeper. The hydraulic movement of water in rills is very different from the movement in other natural channels such as rivers and streams.
