Thermohaline Circulation
What is it?
Thermohaline circulation is large-scale ocean circulation driven partly by seawater density differences associated mainly with temperature and salinity.
In simple words
- Temperature + salinity → density differences → deep circulation.
Recommended for Class 12
Full school-level explanation
Thermohaline circulation is large-scale ocean circulation driven partly by seawater density differences associated mainly with temperature and salinity.
Formula / Key Relation
The word combines: thermo → temperature haline → salinity Cold water is usually denser than warm water. Higher salinity also generally increases seawater density. In some high-latitude regions, cold salty surface water can become dense enough to sink. This sinking contributes to deep ocean circulation. The circulation helps move heat and dissolved substances across ocean basins. Conceptually: Density = function of temperature and salinity Lower temperature → density generally increases. Higher salinity → density generally increases.
Remember
- Density = function of temperature and salinity
