Wetlands and Erosion Concepts

Jose, an intern at the wetlands, explains river processes: weathering, erosion, and deposition. Using a stream table model, he demonstrates these processes in real-time. The video highlights how erosion affects land, the formation of deltas, and the role of wetlands in preventing erosion. Viewers are encouraged to observe these processes in nature.

Which process involves the breakdown of rocks into smaller particles?

• Deposition

• Weathering

• Sedimentation

• Erosion

What is the term for the movement of sediments by water and wind?

• Weathering

• Sedimentation

• Deposition

• Erosion

What is the final process where sediments are laid down in a new location?

• Sedimentation

• Deposition

• Erosion

• Weathering

In the stream table model, what is used to show the strongest current?

• Sand

• Pebbles

• Rocks

• Food coloring

What natural feature is formed when a river deposits sediment in the middle of its flow?

• Delta

• Valley

• Gorge

• Canyon

What is the effect of the strongest current on the land in the stream model?

• It builds up land

• It has no effect

• It creates new rocks

• It erodes the land

What is the main function of wetlands in relation to erosion?

• Enhance deposition

• Cause weathering

• Prevent erosion

• Increase erosion

How do plant roots in wetlands help the soil?

• They break down rocks

• They hold down the soil

• They increase water flow

• They cause erosion

What happens to the current near wetlands compared to other areas?

• It becomes weaker

• It remains the same

• It disappears

• It becomes stronger

Why is it important to observe rivers and streams in real life?

• To measure water speed

• To see weathering in action

• To collect pebbles

• To understand erosion and deposition
