Which process determines cirque orientation, influencing snow accumulation and glacial formation?

💡 Explanation

Prevailing wind direction affects cirque orientation because wind deposits snow preferentially on leeward slopes, favoring glacial formation. Therefore, wind direction is key, rather than weathering, tectonics or vegetation, which do not have the same focused deposition effect that concentrates snow accumulation.
