The pictures show some changes to a river over time. Which best explains how the landform in the river changed over time?

• The river eroded sediments from the landform.

• Rocks under the river were pushed up by faulting.

• Sediments were deposited on the landform from the river.

• Weathering caused the landform in the river to become larger.

The diagram shows a sandbar that has formed along part of a coastline. How did the sandbar most likely form?

• Waves eroded part of the beach

• Gravity pulled sand away from the beach
