What will most likely to happen to The Grand Canyon over time? 

• Wind will continue to erode the rocks.

• The canyon will get deeper as it continues to be eroded by the river and the rocks. 

• A mountain will form where the rock sediments are deposited.

• The river will evaporate, and the canyon will stop changing.

What natural agent most likely caused the formation of a river delta?

• weathering and erosion caused by a moving glacier creates a delta.

• cementation and compaction caused by volcanic eruption creates river delta landforms.

• weathering and erosion by water moves sediments and deposits them at the mouth of a river that meets the ocean.

• weathering and erosion caused by a moving glacier creates a delta.
