stream erosion and deposition

Front

What is stream erosion?

Back

Stream erosion is the process by which flowing water removes soil and rock from the banks and bed of a stream or river.

Front

What factors affect stream velocity?

Back

Stream velocity is affected by the slope of the land, the shape of the streambed, and the amount of water flowing in the stream.

Front

How does a decrease in slope affect stream velocity?

Back

A decrease in slope generally leads to a decrease in stream velocity.

Front

What happens when a stream slows down?

Back

When a stream slows down, it deposits larger rocks first and continues to carry finer sediments.

Front

What is deposition in the context of streams?

Back

Deposition is the process by which sediments are dropped or settled out of the water as the stream's velocity decreases.

Front

How does vegetation affect stream erosion?

Back

Vegetation helps to stabilize soil and reduce erosion by slowing down water flow and providing root structures that hold soil in place.

Front

What is the relationship between stream velocity and erosion?

Back

Faster stream velocities typically lead to more erosion, as the water has more energy to move sediments.

Front

What type of sediment is deposited first as a stream slows?

Back

Larger sediments are deposited first, followed by smaller sediments as the stream continues to slow.

Front

What is the impact of a steeper slope on erosion?

Back

A steeper slope increases the energy of the water flow, leading to more erosion.

Front

What is the role of water in shaping landscapes?

Back

Water shapes landscapes through processes like erosion, transportation, and deposition, creating features such as valleys and deltas.
