Which mechanism primarily controls orientation, asymmetry, and shape of cirques on a mountain range?

💡 Explanation

When mountain receives snowfall, differential snow accumulation patterns develops due to prevailing wind directions because winds deposit more material on leeward side which leads to larger glacier formation and cirque development. Therefore snow accumulation results, rather than heat flow, intrusion, or material variations which affect other processes.
