← GeographyWhich mechanism creates terraces interrupting slope profiles within cirques?
A)Frost heave causes sediment sorting✓
B)Isostatic rebound creates stepped topography
C)Aeolian deposition builds layered dunes
D)Lithospheric flexure induces cyclic uplift
💡 Explanation
Frost heave within a cirque results in terraced profiles because differential expansion and contraction of sediment sorts coarser materials to the surface. Therefore, stepped, terraced surfaces result from frost sorting, rather than isostatic readjustment causing regional uplift.
