Earth's Structure and Composition

The inner core is the hottest layer of the Earth, with temperatures reaching up to 5,700 °C (10,232 °F).

The Earth's crust is primarily composed of silicon, which makes up about 28% of its mass.

The mantle is responsible for the movement of tectonic plates due to convection currents.

The Mohorovičić Discontinuity, also known as the Moho, is the boundary between the Earth's crust and mantle.

The Earth's outer core is primarily composed of iron, with a small amount of nickel.

The mantle is the thickest layer of the Earth, extending from the crust to the outer core.

The Lehmann Discontinuity is the boundary between the Earth's outer core and inner core.

The Earth's inner core is primarily composed of iron, with a small amount of nickel.

The Earth's magnetic field is generated by the movement of molten iron in the outer core.

The Gutenberg Discontinuity is the boundary between the Earth's inner core and mantle.

The Earth's crust is relatively thin, with an average thickness of 10-30 km.

The Earth's mantle is approximately 2,900 km thick.

The Earth's outer core is approximately 2,200 km thick.

The Earth's inner core is approximately 1,220 km thick.

Tectonic plates move due to convection currents in the Earth's mantle.
