What process describes the movement of very fine soil particles carried high into the air?

The process that describes the movement of very fine soil particles carried high into the air is known as suspension. This phenomenon occurs when small, light particles like silt and clay are lifted and carried by wind currents, allowing them to be transported over considerable distances.

Suspension is significant in understanding soil erosion and sediment transport because these fine particles can remain airborne for extended periods and travel far from their original location, contributing to issues like dust storms and air quality problems. In contrast, saltation involves the bouncing movement of slightly larger particles that are not lifted as high into the air. Surface creep refers to the movement of heavier particles that roll or slide along the ground, while aggregation involves the clumping of soil particles together, which does not pertain to their transportation in the air. Understanding these terms is crucial when assessing erosion processes and their impacts on the environment.
