3Agents of Erosion Agents of erosion include -- Running water is the big Kahuna of all erosional agents.
4How does water carry the sediments? Water carries sediments in the following ways:Solution – -Suspension – -Rolling or bouncing along the streambed.Floating – -
5Streams act as conveyor belts River FloorFlow of the RiverCobbles & PebblesMove by sliding, rolling along the river floorSlower than the water flowColloids (Silt & Clay) & Dissolved IonsCarried in suspensionSame speed as waterSandBounces along river floorSlower than the water flow
