← GeographyWhich mechanism limits talus slope formation at arid mountain bases?
A)Salt crystal weathering✓
B)Vegetative root wedging
C)Chemical dissolution increase
D)Cryofracture freeze-thaw cycles
💡 Explanation
Salt crystal weathering is the primary mechanism that limits talus formation due to lack of consistent moisture. Crystallization exerts pressure, breaking down rocks because water evaporates leaving salt behind, therefore the dry condition favors salt-driven breakdown, rather than freeze-thaw.
