← HistoryWhich performance decline occurred during winter for lead Roman aqueducts?
A)Freezing destroyed support arches.
B)Contraction cracked joints between sections.✓
C)Water turbulence drastically increases flows.
D)Thermal inertia maintained constant capacity.
💡 Explanation
Aqueducts experienced contraction cracking, creating leaks, because thermal contraction stressed the lead joints. Therefore, cracking reduces water delivery, rather than the thermal inertia maintaining the flow if construction uses less brittle materials.
