They’re spherical and get lifted into the air like plane wings. These moving particles knock the clay and silt loose into the air, the place they will go several thousand kilometers. Like water erosion, there are three several types of wind erosion, surface creep, saltation, and suspension. Surface Creep: When the wind velocity on the soil surface exceeds 13 miles per hour (21 kilometers per hour), soil particles begin to roll along the soil surface. Saltation: Because the wind speeds pick up, the surface particles start leaping off the surface into the air, this course of is saltation. Suspension: After the saltation begins, the particles hit the surface and knock free other particles, knocking them into the air.
