Rivers & Streams

Front

What are the characteristics of youthful rivers?

Back

Youthful rivers often have steep gradients, fast-flowing water, and features such as rapids.

Front

At which stage of a river's lifecycle is sediment deposition most prevalent?

Back

Sediment deposition is most prevalent in the old stage of a river's lifecycle.

Front

What causes the formation of a sand bar in a stream?

Back

A sand bar forms due to deposition, which occurs when there is a decrease in stream velocity.

Front

What happens to the size of particles a stream can carry as its velocity decreases?

Back

As the velocity of a stream decreases, it can only carry smaller particles.

Front

Where is deposition likely to occur in a river?

Back

Deposition is likely to occur along the inside bank where the water slows down.

Front

Define 'deposition' in the context of rivers and streams.

Back

Deposition is the process by which sediments are laid down or settled in a new location, often due to a decrease in water velocity.

Front

What is the relationship between stream velocity and sediment transport?

Back

Higher stream velocity allows a river to carry larger and heavier sediments, while lower velocity results in the transport of smaller particles.

What are the three main stages of a river's lifecycle?

Back

The three main stages of a river's lifecycle are youthful, mature, and old.

Front

How do meanders form in a river?

Back

Meanders form as a result of erosion on the outer bank and deposition on the inner bank, creating a winding path.

What is the significance of the floodplain in river systems?

Back

The floodplain is significant as it is an area where sediment is deposited during floods, enriching the soil and providing habitat.
