Question

Which one of the following statements is FALSE?

• A. Perched water table exists within the zone of aeration.
• B. Juvenile water is derived from sediment diagenesis.
• C. Zone of aeration lies above the zone of saturation.
• D. Both aquiclude and aquifuge are impermeable.

Hint:

Juvenile = magmatic origin; Connate = sediment-trapped; Meteoric = rainfall-derived.

Answer 1

The Correct Option is B

Step 1: Understanding water classifications.
- Juvenile water: Magmatic origin — derived directly from Earth's mantle, not from sedimentary or surface processes.
- Connate water: Trapped in sedimentary rocks during deposition.
- Meteoric water: Derived from precipitation.
Step 2: Evaluating statements.
(A) True — A perched water table occurs above the main water table within the zone of aeration.
(B) False — Juvenile water originates from magma, not diagenesis.
(C) True — The zone of aeration lies above the saturated zone.
(D) True — Both aquiclude and aquifuge are impermeable.
Step 3: Conclusion.
The false statement is (B) Juvenile water is derived from sediment diagenesis.
