The significance of the Cone of Depression lies in its representation of a reduction in groundwater levels around a well, which is a clear indicator of stress on the aquifer. When water is extracted from a well, the surrounding water table decreases, creating a funnel-shaped depression in the water table known as the Cone of Depression. This phenomenon illustrates how intensive pumping can lower water levels and potentially lead to negative effects such as reduced water availability, increased energy costs for pumping, and potential land subsidence.

The Cone of Depression is crucial for understanding groundwater flow and management. It helps hydrogeologists and water resource managers assess the impact of pumping on surrounding wells and the broader aquifer system. Recognizing this cone allows for better planning in water use and conservation efforts, ensuring that water extraction does not overdraw the aquifer, which could lead to long-term sustainability issues.

Understanding the other choices highlights why they do not pertain directly to the significance of the Cone of Depression. While increased rainfall is part of the water cycle and affects groundwater levels, it does not relate to the localized effects around a well. The age of groundwater is determined by different methods, such as isotopic analysis, and is not illustrated by the Cone of Depression. Moreover, while cleanliness of groundwater is
