1. the force of the river against the banks can
cause air to be trapped in cracks and crevices.
The pressure weakens the banks and gradually
wears it away.
2. rocks carried along by the river wear down the
river bed and banks.
3. rocks being carried by the river smash together
and break into smaller and smoother particles.
4. soluble particles are dissolved into the river.
8. What types of weathering to the
pictures below show?
9. Name the way in which a river can
transport material

Round 2 – River landforms
Upper Course Landforms
10 - Put the river
landform into the
correct course of
the river!
Middle Course Landforms

Lower Course Landforms
Round 3 – 11. How do theses processes and landforms affect the
lives of people living along the river?
Habitats
destroyed
More money
spent in the
area
Social
Anti-social
behaviour
Economic
Increased
traffic
Litter
Environmental
More jobs

12. Flood Hydrographs
1.

it
9.

13. River Management
1. Sustainable
2. Diverting flood
water away from a
settlement
Hard or soft engineering?
6. Cheaper
10. Greater income
11. Less impact on
the environment

Word box
•Drainage basin - E
•Confluence - G
•Source - A

•Channel - F
•Watershed - C
What do the following terms mean?
2. Velocity – speed of the river
3. Erosion – wearing away of weathered material
4. Weathering – breaking up/down of rocks
5. Transportation – movement of
weathered/eroded material
6. Deposition – dropping/dumping of transported
material
7. Match the types of river erosion with
their definitions...
1. the force of the river against the banks
can cause air to be trapped in cracks and
crevices. The pressure weakens the banks
and gradually wears it away.
2. rocks carried along by the river wear
down the river bed and banks.
3. rocks being carried by the river smash
together and break into smaller and
smoother particles.
4. soluble particles are dissolved into the
river.
8. What types of weathering to the
pictures below show?
Freeze-thaw weathering OR
Mechanical/Physical weathering
9. Name the way in which a river can
transport material
SOLUTION
SALTATION
Suspension – fine, light
material is carried along
the river
Traction – large
boulders are rolled
along the river bed
TRACTION
SUSPENSION
Solution – minerals
are dissolved in the
water
Saltation – small pebbles
and stones are bounced
along the river bed
