← HistoryWhich consequence resulted from extensive terrace farming for maize cultivation in the Andean highlands during the Inca empire?
A)Regional climate modification from albedo changes
B)Localized soil anoxia due to waterlogging
C)Increased agricultural biodiversity within microclimates✓
D)Eutrophication of high-altitude mountain lakes
💡 Explanation
When extensive terracing occurred for maize cultivation in the Andes, microclimates formed because varied sun exposure and drainage created diverse thermal conditions, leading to increased agricultural biodiversity adapted to these zones. Therefore increased biodiversity resulted, rather than climate shifts, anoxia, or eutrophication which require different environmental processes.
