They both are the same because they are currents that move like waves
The ocean currents are colder than the currents in the mantle,and the are located in different areas.
Convection currents are located in the astenosphere in boiling water and lots of other places
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
Convection currents
Upwelling of hot mantle materials rising to the cooler surface of the mantle. This constant movement, much like water boiling in a pot, creates a current.
Convection currents occur in the asthenosphere.
Convection currents are currents caused by the expansion of a liquid, solid, or gas as its temperature increases.while colder, denser material sinks.. Convection currents arise in the atmosphere above warm land masses or seas, giving rise to sea breezes and land breezes, respectively. In some heating systems, convection currents are used to carry hot water upwards in pipes. Convection currents in the hot, solid rock of the Earth's mantle help to drive the movement of the rigid plates making up the Earth's surface .
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. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.
which diagram correctly indicates why convection currents form in water when water is heated
