What geological phenomenon accounts for the perennial fresh water emerging from submarine springs along the Lebanese coast?
Answer and explanation
Correct answer: B. Submarine karstic aquifers discharging pressurized groundwater
- Step 1: Snowmelt on Mount Lebanon infiltrates deep into fractured, highly permeable Jurassic limestone strata.
- Step 2: The groundwater flows through subterranean conduits and discharges under artesian pressure directly onto the sea floor.
Answer
Submarine karstic aquifers discharging pressurized groundwater.
Why not the others: 'Desalination of seawater' is an industrial process; 'Condensation of maritime moisture' produces negligible water; 'Tectonic expulsion' does not produce continuous fresh springs.
