Hydrosphere

Oceans, seas, lakes & rivers — all of Earth's water.

Biosphere

Continents with living & non-living organisms.

◈ Inner Zone

Crust / Lithosphere

Silica & aluminium (SIAL). Conrad discontinuity below.

Mesosphere

Rigid zone between Conrad & Mohorovic boundaries.

Mantle (Sima)

Silicate & manganese. Convection drives tectonic plates.

Outer Core (Liquid)

Inner Core — Barysphere

Solid Ni & Fe. Pressure keeps it solid despite ~5,500°C.
