• Weathering

• Erosion

• Deposition

• Compaction

Scientists notice that a river delta has been gradually getting larger and shallower over the past 50 years. What is the most likely reason for this change?

• The river current increases and there is no change in the amount of sediment.

• Sediment is deposited as the river slows down.

• The river current slows down and there is no change in the amount of sediment.

• Sediment is deposited as the river speeds up.
