Ventifacts have also been discovered on Mars, where such sharp immobile rocks have caused significant damage to the wheels of the Curiosity rover. [4] An example of a Martian ventifact was named Jake Matijevic. By analyzing its shape, it was possible to reconstruct the main wind direction which sculpted the rock. [5]
A dreikanter from the Wind River Basin, Wyoming, USA. Property of Western Washington University. Photo by AJ Wakefield, 2012. A dreikanter is a type of ventifact that typically forms in desert or periglacial environments due to the abrasive action of blowing sand.

Let's say you invest $10,000 into an account that pays 3% in simple interest. After three years, you’d have earned $900 in interest — $300 each year — for a total of $10,900 in your account.
Wind erosion of soil at the foot of Chimborazo, Ecuador Rock carved by drifting sand below Fortification Rock in Arizona (Photo by Timothy H. O'Sullivan, USGS, 1871). Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).
