Final answer:
A cone of depression is formed in the water table surrounding a well due to pumping and drawdown.
Step-by-step explanation:
The depression in the water table surrounding a well, which forms as a result of pumping and drawdown, is called a cone of depression. When groundwater is pumped from wells, there is a localized drop in the water table around the well. This cone of depression occurs because the pumping creates a vacuum that draws water out of the surrounding aquifer, causing the water level to drop.
