Question

The global thermohaline circulation that involves the spreading of surface water through the Atlantic and the other ocean basin followed by its rising to the surface and flowing back to the Atlantic where the cycle begins again is called the

Answer 1

The global thermohaline circulation is an essential part of the Earth's water cycle, driven by temperature and salinity gradients, and moderates the global climate by redistributing heat.

Step-by-step explanation:

The global thermohaline circulation referred to in the student's question is a large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. This circulation involves the movement of ocean water masses through rising and sinking due to differences in temperature and salinity, hence the term 'thermo' (heat) and 'haline' (salt).

Upwelling is a process that also plays a critical role in this circulation, bringing nutrient-rich deep waters to the surface, which supports marine life. The thermohaline circulation is sometimes referred to as the 'global conveyor belt' and it has vital implications for the global climate. As it circulates, it helps distribute heat around our planet, which in turn affects weather and climate patterns.

Consequently, the thermohaline circulation helps to moderate the Earth's climate by redistributing heat from the equatorial regions to the poles and returning cooler water to the equator. This process is an essential part of the Earth's water cycle and is crucial for maintaining the climate as we know it.
