F.5 GCE AS Geography - Unit 1.3d - Plenary

Which of the following landform features can be found in the lower course?

• Levees

• Floodplains

• Deltas

• Bluffs

• Plunge pools

Why deltas are formed in the river mouth?

• The river energy is very low there.

• Strong ocean currents can be found there.

• Deposition can be observed.

• Sorting is one of the fluvial processes contributing to its formation

Which of the following conditions are favourable for the formation of deltas?

• Deforestation activities

• Abundant supply of river sediment

• Saline water

• Strong ocean currents

• Gentle offshore gradient

What does the following statement refer to?

Any precipitation that has been intercepted by vegetation then passes down the branches and stems of vegetation.

What does the following statement refer to?

The movement of water from the soil layer to the bedrock.

What does the following statement refer to?

The process of evaporation of water from plants through pores (stomata).

What does the following statement refer to?

The movement of water in the soil under gravity towards the stream channel/parallel to the surface.

Which of the following conditions are favourable for surface run-off?

• Impermeable urban surfaces

• Deforestation activities

• Higher permeability of rock

• Higher drainage density

What does the following statement refer to?

The force of water pushing into cracks and hitting against the rivers’ walls. The collapsing air bubbles create erosive power known as cavitation.

What does the following statement refer to?

A type of fluvial transportation. When river load rolls and is dragged downstream along the river bed.
