Sand Dune Elevations on the Earth, Mars, and Titan
MetadataShow full item record
Sand dunes are observed on many places in the solar system. They are found on bodies with atmospheres and are formed through wind processes. Dunes can tell us about the geological process on the planets they inhabit. Dunes are found on many worlds, including Earth, Mars and Titan. For Titan, the dunes are a major geologic feature, covering most of the equatorial region. Titan’s sand dunes are at a much higher elevation than the rest of the surface. By comparing the dune elevations of Mars and Earth, we hope to determine the reason for the higher than average dune elevations on Titan.
