Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.
When a warm fluid rises and a cool fluid sinks.
This is known as convection.

convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
Huh?
The motion in the mantle is known as convection currents which helps move earth's slabs, known as plates. Convection occurs in the upper mantle known as the asthenosphere.
Convection currents in the Earth's mantle are thought to be responsible for plate motions and therefore can ultimately be considered the cause of earthquakes. Mantle upwelling or mantle plumes are also thought to be the cause of hotpots which cause intra-plate volcanic activity such as that which occurs in Hawaii.
Convection currents are found in the plastic mantle in Earth.
It's mantle with less, then mantle with more as you go deeper into earth.
