Exploring River Features

Explain the term 'meander' in relation to rivers.

• A meander is a type of fish found in rivers.

• A meander refers to the speed of a river's flow.

• A meander is a winding curve or bend in a river.

• A meander is a straight section of a river.

What is an oxbow lake and how is it formed?

• A lake formed by volcanic activity.

• A lake that forms in a straight river channel.

• A lake created by human-made dams.

• A lake that is crescent shaped that forms from cut off meanders.

How do meanders form in a river?

• Meanders are created by the construction of dams along the river.

• Meanders form due to volcanic activity in the riverbed.

• Meanders develop from the influence of tidal forces in the river.

• Meanders form through the erosion of outer banks and deposition on inner banks of river bends.

What is the mouth of a river?

• The mouth of a river is its source.

• The mouth of a river is a type of fish.

• The mouth of a river is where it flows into a mountain.

• The mouth of a river is where it meets a larger body of water.

What are the three main courses of a river?

• Estuary course, floodplain course, canyon course

• Headwaters course, confluence course, basin course

• Upper course, middle course, lower course

• Source course, tributary course, delta course

What role does water flow play in river erosion?

• Water flow is primarily responsible for fish migration.

• Water flow only affects the temperature of the river.

• Water flow is crucial for river erosion as it dislodges and transports sediment, shaping the riverbed and banks.

• Water flow has no impact on river erosion.

Identify one way rivers deposit sediment.

• When the river is frozen.

• When the river slows down.

• When the river speeds up.

• When the river flows uphill.

What happens to a river as it moves from its upper course to its lower course?

• The river becomes wider, deeper, slower, and more meandering.

• The river flows uphill towards the mountains.

• The river dries up completely.

• The river becomes narrower and faster.

How do meanders affect the speed of a river?

• Meanders generally slow down the average speed of a river.

• Meanders increase the average speed of a river.

• Meanders only affect the depth of a river.

• Meanders have no effect on the speed of a river.

What is a delta and how is it formed?

• A delta is created by the erosion of cliffs.

• A delta is formed by volcanic activity.

• A delta is a type of mountain range.

• A delta is a landform created by the deposition of sediment at the mouth of a river.
