Q

Why are upper course valleys V shaped?

A

River erodes vertically down
- causes sides to be attacked by weathering processes
- weakens them and causes mass movement

Q

What are the steps to waterfall formation?

A
  1. Less resistant rock eroded by abrasion and hydraulic action
  2. Hydraulic action continues undercutting and creates plunge pool
  3. Overhang created collapses and waterfall retreats upstream
  4. steep sided gorge is left

Steep edge of a river

17
Q

What landforms are in the lower course?

A

Levees
Floodplains
Large meanders
Oxbow lakes

18
Q

Where are deltas found?

A

In the lower course of a river with a high load as it starts to lose energy

19
Q

What are floodplains?

A

Wide flat areas of land either side of a river susceptible to flooding

20
Q

What is a levee?

A

An embankment built up on either side of a river after it floods

21
Q

How are deltas useful to humans?

A

They provide new farming grounds as the land is very fertile

22
Q

What is a fan shaped delta?

A

When land around the river mouth arches out to sea, splitting the river many times creating a fan effect

23
Q

What is a delta?

A

A low lying area at the mouth of a river where it deposits so much sediment that it extends beyond the coast
