Brief Explanations
To determine the correct answer, we analyze each option:
- Option A: A cone of depression is formed around a well when water is pumped out, causing the water table to slope toward the well. This matches the definition.
- Option B: The area where surface water reaches an aquifer is a recharge area, not a cone of depression.
- Option C: Connecting caves are related to cave systems, not the cone of depression.
- Option D: A collapsed cave is a sinkhole or cave - in, not a cone of depression.
