GENERAL GEOLOGY

Detailed explanation-1: -Traction is the geologic process whereby a current transports larger, heavier rocks by rolling or sliding them along the bottom. Thus, the grains and clasts interact with the substratum during transport. By contrast, saltation, a related sediment transport process, moves grains across the bottom by bouncing or hopping.

Detailed explanation-2: -Traction is the rolling or dragging of large grains along a river bed or shore, aided by the push of the smaller grains (below). Saltation is the bouncing of sand grains as they are picked up, carried along, and dropped repeatedly by flowing water.

Detailed explanation-3: -Definition: Traction is a method of transportation for large stones or boulders in a river. The stones are rolled along the river bottom by the water as they are too large to transport in the water.

Detailed explanation-4: -There are four types of transportation : Traction-large, heavy pebbles are rolled along the river bed. This is most common near the source of a river, as here the load is larger. Saltation-pebbles are bounced along the river bed, most commonly near the source .

Detailed explanation-5: -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.
