Deflation is divided into three categories: ( 1 ) surface creep, where larger, heavier particles slide or roll along the ground ; ( 2 ) saltation, where particles are lifted a short height into the air, and bounce and saltate across the surface of the soil ; and ( 3 ) suspension, where very small and light particles are lifted into the air by the wind, and are often carried for long distances.
