3. 1. River basin features.... Name the features A – G Using the word box below A G Rivers: from source to mouth http://www.gatm.org.uk/geographyatthemovies/rivers.html B C • Word box • Drainage basin • Confluence • Source • Tributary • Mouth • Channel • Watershed F E D

4. What do the following terms mean? 2. Velocity 3. Erosion 4. Weathering 5. Transportation 6. Deposition Sticky does river processes S:\Geography\Academic Year 2012-2013\Year 10 Core Units\Theme 1 - Water\Lesson 3 River Processes\Adtastic2001-StickyRivers422.wmv

5. 7. Match the types of river erosion with their definitions... Animations http://www.bbc.co.uk/schools/gcsebitesize/geography/riverswater/river_processesrev1.shtml • 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. Hydraulic action Corrosion Abrasion/ corrasion Attrition

6. 8. What types of weathering to the pictures below show? A

7. B C

8. 9. Name the way in which a river can transport material SOLUTION SALTATION TRACTION SUSPENSION A C B D

9. Round 2 – River landforms GATM 10 - Put the river landform into the correct course of the river! E C B F D A

10. 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 Anti-social behaviour Social Economic Increased traffic Litter Environmental Hotels cause eyesores More jobs

11. Hydrological cycle http://www.geographyalltheway.com/in/gcse-rivers/igcse_hydrological_cycle.htm

12. 12. Flood Hydrographs • An area of impermeable rock • A basin with gentle valley sides • A river with a dam built across it • A basin with lots of rivers (high drainage density) • An area of permeable rock • A built up area • A basin with steep valley sides • A river without a dam built across it • A basin with few rivers (low drainage density) • An area of forest

13. 13. River Management 1. Sustainable 10. Greater income 6. Cheaper Hard or soft engineering? 2. Diverting flood water away from a settlement 11. Less impact on the environment 3. Dam construction 7. Deepening the river 12. Allow river to flood naturally 4. Widening the river 8. Expensive 13. Enhances environmental quality 5. Big environmental impact 9. Trees planted near a river - afforestation 14. Control urban development

16. 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

17. 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.

18. 8. What types of weathering to the pictures below show? Freeze-thaw weathering OR Mechanical/Physical weathering A

19. B C

20. 9. Name the way in which a river can transport material SOLUTION SALTATION TRACTION SUSPENSION Suspension – fine, light material is carried along the river Solution – 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
