River Erosion

4. – the speed the water is travelling
7. – more resistant rocks that are harder to erode
8. – where the river meets the sea
11. – less resistant rocks that are more easily eroded
12. – material (load) picked up by the moving river is used as a tool of erosion against the bed and banks of the river
13. = the river bed or bank is eroded by the force of the moving water in its channel
14. – the angle of the slope

1. – the area of the riverbed and bank that comes into contact with water
2. – the process of hydraulic action, where bubbles of air collapse in the water creating shock waves that spread out. These shock waves weaken the banks of rivers, especially those composed of sand and clat, causing them to be broken down
3. – how much water there is
5. – where a river begins
6. – soluble rocks in the river channel are dissolved by acids in the water
9. – rocks and pebbles (load) rub against one another as they are moved by the river
10. – wearing away of the land
