Dry source areas with a sparse vegetation cover allow for sand saltation and ballistic entrainment of silt particles, processes that enhance silt deflation and transport. Conversely, surfaces ...

Wind lifts the grains of sand a few inches to a few feet above ... This process, known as saltation, produces much lighter desert dust grains, which descend very slowly due to gravity.

For fine-grained sand the threshold wind velocity for sand ... four main ways: traction or creep, saltation, reptation and/or suspension (Figure 2). Regardless of the mechanism, as sediment ...

Saltation – where small pieces of shingle or large sand grains are bounced along the sea bed. Traction – where pebbles and larger material are rolled along the sea bed.
