A rock that has been shaped or polished by the sandblasting effect of wind-blown sand.
A rock naturally shaped and polished by the wind-blown sand material being used as an abrasive.
A stone that has been flattened and sharpened by wind abrasion. Ventifacts are commonly found strewn across a desert floor.
A pebble or cobble shaped and polished by wind abrasion.
A rock that exhibits the effects of sandblasting or "snowblasting" on its surfaces, which become flat with sharp edges in between.
A desert rock whose surface has been faceted by the wind.
A loose piece of rock that has been polished smooth by wind transported particles. Common in arid environments.
A stone whose form has been modified by the sand-blasting effect of wind-carried sediments. Ventifacts are common in deserts.
A general term for any stone or pebble shaped, worn, faceted, cut, or polished by the abrasive or sandblast action of windblown sand, generally under desert conditions. An example from Death Valley can be seen here.
a result of moving air and hard particles operating on rock
a stone that has been eroded by windblown particles, such as dry sand
facetted or triangular-shaped stone formed by sand-blasting in strong winds, often polished to a high degree.
A stone with its form modified by the sand-blasting effect of wind-carried sediments. Ventifacts are common in periglacial zones as well in deserts. See dreikanter.
A pebble faceted or moulded by wind action, usually formed in desert or polar areas. The flat facets meet at sharp angles.
Ventifacts are rocks that have been abraded, grooved, or polished by wind driven sand. These geomorphic features are most typically found in arid environments where there is little vegetation to interfere with eolian particle transport, where there are frequently strong winds, and where there is a steady but not overwhelming supply of sand.
