Barrier Islands and Salt Marshes

The video explores landforms created by deposition, focusing on river deltas, barrier islands, and salt marshes. River deltas form when sediment-laden rivers slow down upon reaching a body of water, depositing sediment that can create triangular or bird-foot shaped deltas. Barrier islands are long, narrow islands formed by sediment transported by waves and currents, protecting the mainland from erosion. Salt marshes are coastal wetlands with salt-tolerant plants, providing habitats for wildlife and offering storm protection and carbon storage.

What is the primary process that leads to the formation of landforms like river deltas?

• Deposition

• Sedimentation

• Erosion

• Weathering

Which of the following is NOT a shape that a river delta can take?

What is the main function of barrier islands?

• To filter water

• To protect the mainland from erosion and storm surge

• To store carbon

• To provide a habitat for dolphins

How are barrier islands primarily formed?
