What is the term for the underground layer where groundwater accumulates?

• A. Aquifer
• B. Reservoir
• C. Well
• D. Cistern

Answer: (A)

An aquifer is the correct term for the underground layer where groundwater accumulates. Aquifers are geological formations that can store and transmit water, making them crucial sources of water for various uses, including drinking, agriculture, and industry. They are typically composed of materials such as sand, gravel, or porous rock that allow water to flow through them effectively. In contrast, a reservoir refers to an artificial or natural lake where water is stored, often created by damming a river. A well is a structure created to access water from an aquifer, usually drilled into the ground to reach the water. A cistern is a storage tank, often used to collect rainwater or other sources, not specifically referring to an underground layer of water accumulation like an aquifer does. Understanding the role of aquifers in the water cycle and their importance in groundwater management is essential for water treatment and conservation efforts.
