← HistoryWhich geological consequence accelerated travertine formation in Roman aqueducts?
A)High calcium carbonate concentration
B)Low water flow velocities✓
C)Presence of iron oxides
D)Decreased atmospheric carbon dioxide
💡 Explanation
Low water flow promoted greater limestone precipitation through the mechanism of chemical sedimentation because water had more contact time with surrounding geological structures; therefore, flow restrictions developed, rather than higher overall water volume transported throughout the aqueduct systems.
