Transportation – The movement of material by suspension, solution, traction and saltation
Types of transportation:
Suspension: Fine, light material is carried along by the river.
Solution: Minerals are dissolved in the water.
Traction: Large boulders and rocks are rolled along the river bed.
Saltation: Small pebbles and stones are bounced along the river bed.
To remember that transportation moves in four ways – suspension, solution, traction and saltation – recall the following:
Transport (transportation) was the solution (solution) to moving the large suspenders (suspension) so a tractor (traction) was used, but they had to salt (saltation) the roads first.
