WebApr 14, 2024 · The temperature changes significantly from the outer core to the crust of the Earth. At the outer core, temperatures can reach up to 5,500°C (9,932°F) due to the intense pressure and heat generated by the Earth's radioactive decay and residual heat from its formation. WebAug 1, 2024 · The pressure at Earth's core, you might imagine, is extremely high — 3.5 million times higher than the pressure you experience up here on the surface. You might expect, then, that iron crystals would take on a hexagonal formation there. Scientists did too: They believed that a cube structure simply couldn't exist in those conditions.
