Geography- river processes

Proccesses of erosion

2 types: vertical and lateral

4 procceses of river erosion

Hydraulic action- the force of water hitting the river bed and bank. Most efffective when water is moving fast at high volume.

Abrasion- The load carried by the river hits the bed or the banks, dislodging particles.

Attrition- Stones carried by the river knock against each other, becoming smaller and more rounded

Solution- Alkaline rocks e.g. limestone are dissolved by slightly acidic river water 

Processes of transporation

material transported by river= load

4 main types:

solution- dissolved load

suspension- small sediment…
