Question

How Does Earth's Interior Work?

Answer 1

Well the interior is broken down into 3/4 layers: The upper and lower Mantle, the outer core and the inner core. Those are listed in order of their depth with the upper mantle merging into the crust and the inner core being the centre of the earth.

The mantles are semi-solid and made primarily of oxygen, silicone and magnesium, the mantle is responsible for most of the earth's mass. The mantle also has convection currents that create 'hotspots' under the earths crust, such hotspots are responsible for creating island chains like Hawaii.

The outer core is a layer about 1500miles wide  and made up of molten iron mixed in with other ligher elements, the convection and spinning of this layer is what gives the earth its vital magnetic field.

The inner core is a sphere of solid iron and nickel at a temeprature of around 3700C. It is solid due to the immense pressure exerted on it by all of the above material.

The way the core is layered is all to do with the different densities of the material that earth was originally formed from. The most dense elements (e.g. iron) sank to the core while lighter elements make up the mantle and crust.

All of this heat in the earths interoir comes from the decay (fission) of nuclear elements. The earth is like one giant nuclear reactor, but it isn't dangerouslty radioactive, just very well insulated to keep in all the heat.

Hope this answers some of your questions.
