← HistoryWhich environmental shift increased flood risk to Andean terraced farming systems during the Little Ice Age?
A)Glacial meltwater volume increase✓
B)Reduced rainfall due to altered winds
C)Increased soil erosion from deforestation
D)Saltwater intrusion from rising sea levels
💡 Explanation
When temperatures dropped during the Little Ice Age, increased glacial ice formation occurred, but warmer periods caused accelerated glacial melt; meltwater volume increased which overflowed irrigation systems in the growing seasons, increasing flood risk. Therefore, glacial meltwater is the primary risk rather than other regional impacts.
