Meanders and Oxbow lakes

What is a meander?

• The deep side of a river, where the flow is fastest and where erosion occurs.

• A canyon like formation which a river flows through

• A bend in a river due to erosion

• A standalone body of water with the shape of a horseshoe

What is an oxbow lake?

• A standalone body of water with the shape of a horseshoe

• A meander

• Where the river deposits its content

• A body of water present in the lower course of the river.

Where does hydraulic action take place when forming a meander?

• The fastest and shallowest part of the river

• The slowest and shallowest part of the river

• The slowest and deepest part of the river

• The fastest and deepest part of the river

True or false? Most rivers flow in a straight line throughout its journey to the sea.

• False

• True

Which direction does a river bend?

• To the east

• To the west

• No fixed direction

• Downwards

As the meander is formed, what happens to the neck of the meander?

• It gets wider

• It erodes, making it narrower

• Nothing

• It curves

What happens in the slip off slope?

• Deposition

• Abrasion

• Hydraulic action

• Traction

What happens in the river cliff?

• Deposition

• Suspension

• Erosion (Hydraulic action)

• Saltation

When the neck has fully eroded, what route does the river take?

• The old meander

• The new, straight route

What happens to the old meander once the neck has eroded?

• It eventually disappears due to evaporation

• It erodes until a circular lake is made.

• It remains the same

• It eventually gets blocked from the river by deposition
