Sediment/material scraping or wearing something away
1 of 27
Attrition
Sediment/material wearing away other material in a sandpaper-like effect
2 of 27
Bedload
Large sediment blocks transported along the river bed
3 of 27
Confluence
Two rivers merging into one larger river
4 of 27
Corrosion
Chemicals in river that wear away river walls
5 of 27
Discharge
Volume of water flowing through a river channel
6 of 27
Drainage basin
Area of land around river that is drained by the river & tributaries
7 of 27
Flood plain
Flat area next to a river that will be affected through floods
8 of 27
Freeze-thaw weathering
Process of water entering cracks in rock and freezing overnight, causing the ice to expand and break away material
9 of 27
Gorge
Process by which the water flowing down a river falls down a waterfall and into a plunge-pool, allowing it to undercut the hard rock by eroding soft rock and causing waterfall to retreat
10 of 27
Hydraulic Action
Process of water forcibly acting on weaker areas of rock/material
11 of 27
Lateral erosion
Horizontal erosion outside a meander channel
12 of 27
Meander
A bend in the river course
13 of 27
Mouth
Where a river enters an area of open water, e.g. a lake or the sea
14 of 27
Ox-Bow lake
Forms when a meandering river erodes through the neck of one of the other meanders. River flows through fastest course, and so deposition blocks off surplus course = Ox-Bow lake
15 of 27
Physical Weathering
A process that breaks rocks apart without altering their chemical composition, e.g. ice or rain
16 of 27
Plunge Pool
A deep basin of water at the foot of the waterfall, caused by hydraulic action with help from gravity
17 of 27
River cliff
On the outside of the meander bend with the fastest flowing water = easily eroded
18 of 27
Slip-off slope
Depositional landform on the inside bend of a river meander
19 of 27
Saltation
Pebbles bounced along the river bed
20 of 27
Solution
Transport of dissolved chemicals
21 of 27
Source
The place where the river begins: usually beginning in v-shaped valleys in hilly areas
22 of 27
Traction
Transportation of rocks along the river bed
23 of 27
Tributary
A small stream flowing into a larger river/stream
24 of 27
Waterfalls
Water dropping from a higher point to a lower point. Usually result in gorges
25 of 27
V-shaped valley
A hilly area of land that has been eroded by a river or stream, giving it its parabolic shape
26 of 27
Watershed
A dividing ridge/area of land that
