Quizplus · Accepted Answer

When groundwater is pumped out faster than it can be replaced, a cone of depression forms on the water table. This means that the water table around the well is lowered and the water pressure decreases, causing the water to flow towards the well. This can lead to a decreased flow of water in nearby streams and rivers, and can even cause the well to run dry. Option A and B are not correct as they do not describe the actual process that occurs when groundwater is over-pumped.
