Solution- dissolved minerals along with solution.
Suspension- fine, light material arrived through water.
Saltation- small pebbles bounced along river bed.
Traction- large boulders along river bed.

Question 1

What are the types of Erosion?

Answer 1

• Hydraulic action
• Abrasion
• Attrition
• Corrosion/solution

Question 2

What are the directions of Erosions?

Answer 2

• Vertical, the downward action-deepens river channel.

- Lateral Erosion, sideways action erosion-widens river channel.

Question 3

What are the features of upper course?

Answer 3

~Narrow and shallow (1.5m)
~Large angular bed load
~Steep V shaped Valley 
~Waterfalls and rapids 
> transportation: traction and saltation

Question 4

What are the features of the Middle course?

Answer 4

~wider channels (5-15m) 
~Deeper river channels 
~Smaller angular bed load 
~Meanders and ox bow lakes 
> transportation: suspension, solution

Question 5

What are the features of the lower course?

Answer 5

~wide and deep channels
~suspended
~floodplain a and levees 
~deltas and estuaries 
> transportation: suspension, solution
