Round 1 - River Processes

1. River basin features....

Name the features A – G Using the word box below

Word box •Drainage basin•Confluence•Source•Tributary•Mouth•Channel•Watershed

Rivers: from source to mouth

What do the following terms mean?

2. Velocity

3. Erosion

4. Weathering

5. Transportation

6. Deposition

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.

1. River basin features....

Name the features A – G Using the word box below

Word box •Drainage basin - E•Confluence - G•Source - A•Tributary - B•Mouth - D•Channel - F•Watershed - C

Rivers: from source to mouth

http://www.gatm.org.uk/geographyatthemovies/rivers.html

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

Suspension – fine, light material is carried along

the riverSolution – minerals are dissolved in the

water

Traction – large boulders are rolled along the river bed

Saltation – small pebbles and stones are bounced

along the river bed
