Erosion can take many forms. Most commonly known is water wearing away the sides of creeks or lakes. But wind can erode just as effectively, especially if it carries dust particles that can eat away at otherwise solid objects. While this wind-driven process is most commonly observed on Earth, it plays a role in the history of most other rocky bodies that have an atmosphere. Recently, a team lead scientists from the Planetary Science Institute found evidence for some erosion from between 50,000 and a few million years ago in Mars’s polar ice cap. That is a blink of the eye by geological standards.
