Erosion, Transporation And Deposition Flashcards
What is the first process of transportation?
Traction, where large particles like boulders are pushed along the river bed by the force of the water
What are the four processes of erosion?
Hydraulic action, corrasion, attrition and corrosion
What is deposition?
A river drops the eroded material it’s transporting
Where are waterfalls and gorges found?
In the upper course of a river
What creates a plunge pool?
The collapsed rocks are swirled around at the foot of the water fall
In which way does the upper course of the river erode?
Vertically downwards
What is formed by eroding and depositing?
Ox bow lakes
What is saltation?
Pebble-sizes particles are bounced along the river bed by the force of the water
What is suspension?
Small particles like silt and clay are carried along by the water
What is solution?
Soluble materials dissolve in the water and are carried along
