What type of wind erosion can lead to the formation of dust storms?

Suspension is the correct choice because it describes the process where fine particles, such as dust, are lifted into the air by strong winds. This airborne dust can remain suspended in the atmosphere, potentially traveling long distances before settling back to the ground. When these conditions are widespread and severe, they can lead to the formation of dust storms, which can significantly reduce air quality and visibility, as well as impact health and agriculture.

In contrast, creep involves larger soil particles rolling or sliding along the ground surface, which does not contribute to airborne dust. Saltation refers to the bouncing movement of particles that are larger than those involved in suspension and typically does not result in the same high levels of air pollution or visibility reduction associated with dust storms. Sheet erosion is a type of surface erosion where thin layers of soil are removed across a large area but does not specifically pertain to airborne particles or dust storms.
