The Great Conveyor: Thermohaline Circulation

Beneath the wind-driven surface currents lies a slower, deeper circulation system driven not by wind but by differences in water temperature and salinity. Thermohaline circulation explained covers how dense, cold, salty water...

Questions: 20 | Attempts: 32 | Last updated: Mar 3, 2026

Sample Question 1
What do the Greek roots "thermo" and "haline" refer to in the context of oceanography?

Heat and Salt

Wind and Tide

Pressure and Depth

Light and Dark

Waves and Current

Sample Question 2
Thermohaline circulation is primarily driven by differences in water density rather than surface winds.

True

False

Sample Question 3
Which of the following changes would cause a parcel of ocean water to become more dense and contribute to thermohaline circulation?

The water cooling down

The water becoming saltier

The water heating up

Evaporation of surface water

Addition of fresh river water
