Blown away on Earth and Mars

Blown away on Earth and Mars
Blown away on Earth and Mars Wind-driven sand can “completely change” rock shapes in a relatively short amount of time geologically speaking, said Sullivan, as he showed images of rocks that have been shaped by aeolian abrasion during his LPSC presentation. From the Coachella Valley on Earth (left) to a crater named Fram on Mars (right), winds have visibly altered the shape and textures of rocks. Rob Sullivan (left) / NASA / JPL-Caltech / Cornell / ASU
