Which of the following is a process of wind erosion?

Deflation is a process of wind erosion. It occurs when wind removes loose, fine-grained particles such as sand, silt, and clay from the surface of the Earth. As the wind moves across the ground, it picks up loose particles and carries them away, leaving behind a depression in the ground. Deflation can also lead to the formation of sand dunes, which are hills of sand that are shaped by the wind. When the wind slows down, the sand particles fall out of suspension and are deposited on the ground. This process is known as deposition. The other options listed, such as saltation, solution, and traction, are also processes of wind erosion but they are not the correct answer to the question. Saltation is the movement of particles in a bouncing motion along the ground, while solution involves the dissolution of minerals by wind-carried moisture. Traction is the process of large particles being dragged along the ground by the wind.
