How are convection currents in the oceans formed?

Convection in the ocean is caused by a negative buoyancy force, that is, whenever denser fluid happens to exist above lighter fluid. The top-heavy situation overturns to seek a situation of lower potential energy. read more

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. read more

In the ocean, convection heating is responsible for the ocean currents, which also affect the weather patterns. Convection currents occur in the magma of the Earth. These currents drive plate tectonics. Radioactive decay in the core of the Earth produces enough heat to melt the rocks that form magma. read more
