This is formed when more water is being used up than replenished

• A. Cone of Depression
• B. Artesian condition
• C. Recharge
• D. Cone of Depression

Answer: (D)

When groundwater is drawn down faster than it can be replenished, the water table around a pumping well drops, creating a cone-shaped area of lowered groundwater called a cone of depression. As water is pumped out, the hydraulic head near the well decreases, and surrounding water moves toward the well to fill the void, forming that downward-angled shape in cross-section. Recharge is the process that adds water back into the aquifer, so it would raise or restore the water table rather than create a depression. An artesian condition occurs when an aquifer under pressure forces water upward, not when pumping causes a drop around a well.
