Question

A rock body through which ground water flows is called

• A. Lake
• B. Artesian well
• C. Springs
• D. Aquifer

Hint:

Think of an aquifer as an underground "river" or "sponge" made of rock and sand. It's the container and conduit for groundwater. Wells and springs are just ways for that water to be accessed or to escape.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question asks for the correct hydrogeological term for a rock formation that can store and transmit a significant quantity of groundwater.
Step 2: Detailed Explanation:
Let's define the given terms:


Lake: A large body of fresh water on the Earth's surface. It is surface water, not groundwater within a rock body.

Artesian well: A well in which water flows upward under its own pressure. It is a structure used to access water from an aquifer, not the rock body itself.

Springs: A location where groundwater naturally emerges from the Earth's surface. It is a feature resulting from an aquifer, not the aquifer itself.

Aquifer: A body of porous and permeable rock, sand, or gravel that can store and transmit groundwater. This definition directly matches the description in the question. Aquifers are the sources for wells and springs.

Step 3: Final Answer:
A rock body through which groundwater flows is called an aquifer.
