A student observes sediments as they are carried downstream by a rapidly flowing river. The student argues that the river is depositing the sediments. Is the student correct? A.
Yes. The river is depositing the sediments.
B.
No. Deposition is the movement and eventual settling of whole rocks, not rock fragments and sediments.
C.
No. The river is eroding the sediments; deposition will happen when the river slows and the sediments settle on the riverbed.
D.
No. The sediments still have the same chemical composition as the rock they came from; deposition follows chemical changes only.
