Question

Quizplus · Accepted Answer

Rocks that are pitted and grooved, and sometimes polished smooth by eolian processes are called ventifacts. These features are created by the abrasive action of windblown particles, such as sand and gravel, striking the rock surface. Over time, this can result in the formation of pitted and grooved depressions, as well as smooth polished surfaces, on the rock. Ventifacts are common in desert environments where wind erosion is a dominant geological process.
