The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

Alternatively, as shown in the diagram, convection currents under the Earth’s crust transfer heat, which rises through the surface and cools back down in a circular motion. The convection ...

Mainly made of hot nickel and iron, convection currents coupled with the Earth's rotation force the liquid metal in this layer into long vertical vortices running in a north-south direction ...

Researchers had long suspected the Earth had another layer at its core ... Its solidification causes convection in the outer core. Convection is "the engine that powers the dynamo that converts ...

Earth's diameter is about 7,900 miles. The planet's internal structure comprises four layers: a rocky crust ... allowing life to flourish on Earth. "Convection in the outer core sustains the ...

Other theories suggest that this deformation could be caused by interactions with structures in the lower mantle (which separates the core from the Earth’s crust), or perhaps even convection ...
