Describe the processes by which a river transports its load.

Answer:

-Traction process-the large and heavy loads of the river are rolled or dragged along
the river by the force of moving water and gravity.
-Saltation-some large fragment that cannot remain suspended in the water are momentarily lifted and dropped by water turbulence. The series of hops move the load down the river.
-Suspension-light insoluble materials such as sand and slit grains are carried and
maintained within the water by river turbulence and transported downstream.
-Solution process-the soluble minerals or materials are dissolved in the river water and carried away.
