Question

Quizplus · Accepted Answer

A primary effect of drought is a drop in groundwater levels. This occurs because there is less precipitation, leading to less water replenishing underground aquifers. As a result, wells may run dry, and water sources for agriculture and other purposes may become scarce. Rolling blackouts (A) may be a secondary effect of drought if power plants rely on water for cooling and there is not enough water available. Decrease in tourism (C) is also a secondary effect if a particular area's economy relies heavily on water-based recreational activities. Low dissolved oxygen content in reservoirs (D) may also be a secondary effect if water levels are low and there is less mixing of oxygenated surface water with deeper, stagnant water.
