Which primary mechanism dictates cirque orientation disproportionately towards northeastern aspects in the Northern Hemisphere?

💡 Explanation

When northeastern aspects are prevalent, reduced insolation occurs because these slopes receive less direct sunlight, slowing snowmelt and promoting glacier formation within the cirque. Therefore reduced solar radiation dictates orientation, rather than moisture, rock susceptibility, or chemical weathering all of which have lesser effects.
