← HistoryWhich consequence results when winter frost affects Inca stonework?
A)Increased stone block expansion
B)Formation of surface salts
C)Water wedging crack propagation✓
D)Quipu record deterioration accelerated
💡 Explanation
Inca stonework joints were susceptible to freeze-thaw cycles. Water expands during the process of ice crystal wedging in small crevices found within rough materials such as stone; therefore, this expands pre-existing cracks, rather than altering the stone chemistry or affecting record keeping.
