Sediment Transport and River Deltas

River deltas form when rivers carrying sediment reach a body of water, slowing down and depositing sediment. This process, influenced by weathering and erosion, can create landforms like the triangular-shaped river delta. Not all deltas are triangular; some, like the birdfoot delta, have unique shapes. Famous examples include the Colorado, Mississippi, and Nile River deltas. The video concludes with a reminder to be kind.

What happens to the sediment carried by a river when it reaches a body of water?

• It continues to flow without change.

• It evaporates.

• It is deposited as the river slows down.

• It dissolves in the water.

What is the process called when materials are worn away and transported by natural forces?

• Weathering

• Sedimentation

• Erosion

• Deposition

How does sediment deposition contribute to the formation of landforms?

• It creates valleys.

• It leads to volcanic eruptions.

• It builds up over time to form landforms.

• It causes earthquakes.

What shape is a river delta typically associated with?

• Rectangle

• Triangle

• Circle

• Square

Why is a river delta named after the Greek letter Delta?

• Because it is square-shaped.

• Because it is rectangular.

• Because it resembles a triangle.

• Because it is circular.

What is a birdfoot delta?

• A delta with a square shape.

• A delta with few widely spaced distributaries.

• A delta with a circular shape.

• A delta with many closely spaced distributaries.

Which of the following is an example of a famous river delta?

• Amazon River delta

• Colorado River delta
