What layer of Earth and interior where convection currents occur?
Convection currents are found in the mantle.
in the mantle due to the molten rock... hope this helps!!! =] also for better detail they happen in the asthenospheric mantle to
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
Mantle is one, and I'm gonna guess core.
The heat from the gradual decay of long lived radioisotopes creates areas of upwelling within the mantle material. The material that rises causes adjacent material to desc…end to fill the void. This motion occurs over very broad areas, and is what drives sea floor spreading and plate tectonics. It all boils down to nuclear decay.
Convection occurs towards the center of the Earth. The center is mostly made of molten iron, which is a fluid. Because convection is the transfer of heat throughout fluids, if… one area is very hot, then the iron flows around and makes other areas warmer.
Convection currents take place in the mantle.
The convection currents flow in the mantle.
In the Upper Mantle, and on the Core of the Earth's surface.
the convection currents will sink and rise again when its heated
Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in… the aesthenosphere.
just the mantle
Heat from the earth's interior causes warmer sections of the softer layer, the asthenosphere, to become buoyant and rise, displacing cooler sections of the asthenosphere, whic…h then sink. These convection currents drive the movement of the lithospheric plates that float on top of the asthenosphere.
Convection currents is similar to convection of heat (hot air rises, cold air falls and replaces hot air etc). The movement of these convection current in the earth's core and… liquid mantle, causes the earth's crust to move...causing earthquakes etc.
