摘要: Aeolian processes contribute to surface landforms on several bodies in our solar system. Sediment transport is responsible for a broad range of geophysical phenomena, including dust storms Earth and Mars the formation migration dunes both planetary bodies, as well Venus Titan. This chapter briefly discusses characteristics sediment transport, presents open questions that need be addressed improve understanding geomorphology, with emphasis dune migration. The geomorphic generate aeolian entrainment have changed through time Mars. Observations active bedforms demonstrate saltation occurring Mars, so some attrition likely happening. Rocks been abraded by windborne particles are common Martian observed at four Rover landing sites.
