The main difference between creep saltation and suspension is the type of particles involved in them. Creep is a geological process where heavy particles in soil are moved by wind erosion, and saltation is a geological process where fine particles are moved by wind erosion. On the other hand, suspension is a geological process in which dirt and dust particles are moved by wind erosion.
Wind erosion is a geological process where erosion takes place due to the effect of wind. It is a serious problem in the environment because it can damage vegetation by removing soil or depositing soil. Therefore, wind erosion causes soil loss, dryness, deterioration of soil structure, nutrient and productivity loss of soil, and air pollution. Wind erosion can move dust particles, fine particles, as well as heavy particles.

Creep, Saltation, Suspension
What is Creep
Creep is a type of wind erosion which includes the movement of heavy soil particles from one place to another due to the action of wind. However, large soil particles are too heavy to be lifted to air; these soil particles are moved through the wind as a surface process. Therefore, we call this process surface creep.
Generally, this process involves the rolling of large particles across the surface after coming into contact with the soil particles in the saltation process.
What is Saltation
Saltation is a type of wind erosion which includes the movement of fine soil particles from one place to another due to the action of wind. The majority of soil particles in an area are moved through this saltation process. The fine particles can be lifted to the air by wind, and they are then drifted horizontally across the surface of the soil.
In saltation, the soil particles move in a velocity that increases with the time. This means an acceleration in the speed of soil particle occurs during saltation process. Saltation can cause severe damages to crop and other vegetation on the soil surface. Typically, fine particles are moved four times longer in distance, compared to their height from the ground.
What is Suspension
Suspension is a type of wind erosion that involves the movement of dirt and dust particles through the wind. This process involves very small particles that readily lift into the wind. These particles can be lifted to the air either through the impact of other particles or by the wind itself. When these particles are lifted to air, the wind can carry them to extreme heights and very long distances.
Difference Between Creep Saltation and Suspension
Creep is a type of wind erosion that involves the movement of heavy soil particles from one place to another due to the action of wind. Saltation is a type of wind erosion that involves the movement of fine soil particles from one place to another due to the action of wind while suspension is a type of wind erosion that involves the movement of dirt and dust particles through the wind.
Creep involves heavy particles while saltation involves fine particles and suspension involves very small dirt and dust particles.
Creep involves short distances while saltation involves long distances and suspension involves very long distances.
Particles in Air
While creep moves particles mostly on the surface of soil rather than in air, suspension readily lifts particles to the air. In saltation, particles can be lifted to the air by the wind or particle collision.
Wind erosion is a geological process where erosion takes place due to the effect of wind. There are three types of wind erosion as creep, saltation, and suspension. The main difference between creep saltation and suspension is that creep involves the movement of heavy particles and saltation involves the movement of fine particles, whereas suspension involves the movement of dirt and dust particles.
