River Landforms Quiz

What is the significance of a river estuary?

• It is where the river begins

• It is where the river meets the sea

• It is a highland area

• It is a narrow valley

What is the role of erosion in river landforms?

• It creates flat plains

• It forms steep valleys and gorges

• It deposits sediment

• It creates deltas

What is the main feature of a gorge?

• It is a wide, flat area

• It is a deep, narrow valley

• It is a highland area

• It is a shallow, wide channel

What is a plunge pool?

• A deep and turbulent pool formed at the base of a waterfall

• A shallow pool formed by sediment deposition

• A pool formed by river meandering

• A pool formed by glacial melting

What happens to the overhanging rock in a waterfall over time?

• It collapses and retreats upstream

• It becomes stronger

• It forms a new river channel

• It remains unchanged

How long can the retreat of a waterfall take to form a gorge?

• Hundreds or even thousands of years

• A few days

• A few weeks

• A few months

What are meanders in the context of river landforms?

• Sharp turns in a river

• Wide bends of a river found mainly in lowland areas

• Narrow channels in a river

• Waterfalls in a river

What is the thalweg in a meandering river?

• The deepest part of the river

• The line of fastest flow (velocity) within the river

• The shallowest part of the river

• The area with the most sediment

What is the role of the thalweg in erosion?

• It prevents erosion

• It causes erosion on the outside bend

• It causes erosion on the inside bend

• It has no role in erosion

What is the significance of the slip-off slope in a meander?

• It is where erosion is most intense

• It is where deposition occurs

• It is where the river is deepest

• It is where the river is narrowest
