What is the difference between eolian saltation and fluvial saltation?

Short Answer

Expert verified
The difference between eolian saltation and fluvial saltation lies in the transport medium and environment. Eolian saltation is driven by the wind, often in arid environments, while fluvial saltation is driven by flowing water, typically seen in rivers and streams.

Step by step solution

01

Definition of Eolian Saltation

Firstly, Eolian saltation is defined as the movement of particles over an uneven surface in a turbulent flow of air. This process commonly occurs in arid and semi-arid environments, often creating dust storms and sand dunes.
02

Definition of Fluvial Saltation

Secondly, Fluvial saltation on the other hand, refers to the hopping movement of sand or gravel caused by the mechanical action of flowing water. This process is most notable in rivers and streams, contributing to the creation of features such as river beds and banks.
03

Comparison of Both Processes

Finally, the two processes should be compared. The main difference is the major transport medium - air for eolian saltation and water for fluvial saltation. Therefore, eolian saltation is typically seen in arid environments where loose particles can be picked up by the wind, while fluvial saltation is common in water bodies like streams and rivers, where the flowing water causes particles to leap and hop downstream.
