Name two upland river landforms.

• Meanders and oxbow lakes

• Waterfalls and gorges

• Floodplains and deltas

• Estuaries and levees

Define the term plunge pool.

• A shallow pool at the top of a waterfall

• A deep pool at the base of a waterfall formed by hydraulic action and abrasion

• A pool formed by the deposition of sediment

• A pool created by lateral erosion

True or False? V-shaped valleys are formed by lateral erosion.

• True

• False

What are interlocking spurs?

• Sharp bends in a river

• Alternating ridges of land that project into a river valley in upland areas

• Flat areas on either side of a river

• Deep pools at the base of waterfalls

Define the term meander.

• A straight section of a river

• A bend in the course of a river

• A deep pool at the base of a waterfall

• A flat expanse of land on either side of a river

True or False? Waterfalls often form where soft rock overlies hard rock.

• True

• False

How do oxbow lakes form?

• By the deposition of sediment in a river

• When a meander is cut off from the main river channel during a flood

• By the erosion of interlocking spurs

• By the formation of a plunge pool

What is a floodplain?

• A deep pool at the base of a waterfall

• A flat expanse of land on either side of a river formed by the migration of meanders and the deposition of sediment

• A sharp bend in a river

• A ridge of land projecting into a river valley

Which of the following is not an upland river landform?

• Waterfall

• Gorge

• Delta

• V-shaped valley

Which process is primarily responsible for the formation of V-shaped valleys?

• Lateral erosion

• Vertical erosion

• Deposition

• Hydraulic action
