Ocean Conveyor Belt: a 3D model for Class 11 Social Science, covering Ocean currents are set going by winds, by differences in water density and by the Earth’s rotation., Warm currents such as the Gulf Stream carry tropical heat poleward; cold currents bring polar water toward the equator., The Gulf Stream and North Atlantic Drift keep north-west Europe far milder than other places at the same latitude., Near Greenland the salty surface water cools, grows denser and sinks: the start of the deep thermohaline circulation., The deep water crawls south, round Antarctica and into the Indian and Pacific Oceans, taking about 1000 years to return..

Topics

Ocean currents are set going by winds, by differences in water density and by the Earth’s rotation.
Warm currents such as the Gulf Stream carry tropical heat poleward; cold currents bring polar water toward the equator.
The Gulf Stream and North Atlantic Drift keep north-west Europe far milder than other places at the same latitude.
Near Greenland the salty surface water cools, grows denser and sinks: the start of the deep thermohaline circulation.
The deep water crawls south, round Antarctica and into the Indian and Pacific Oceans, taking about 1000 years to return.
Where winds push surface water away, nutrient-rich deep water wells up: the Peru coast is a great fishing ground.
The Coriolis effect bends currents into gyres: clockwise in the northern hemisphere, anticlockwise in the southern.
In El Niño years the trade winds weaken, warm water slides east to Peru, upwelling stops and rainfall patterns flip.
