Wind a shaping force on Mars


www.dlr.de said:

The northern hemisphere of Mars is a single, massive lowland with only a few distinctive landscape features. Frequent, intense dust and sand storms are recurrent here over the course of the seasons. When this happens, the wind transports very small particles, which are either deposited in other locations, or, if they encounter rock, leave their mark through the effects of erosion. This type of wind erosion is also referred to as aeolian corrasion. Besides the extensive dune fields, wind-carved structures called yardangs, which are in line with the direction of the prevailing wind, are the most striking legacy of the power of the winds on Mars.
