Nettet15. apr. 2024 · The mantle is about 2,900 kilometers ( 1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume. How hot is the inner core? New measurements suggest the Earth’s inner core is far hotter than prior experiments suggested, putting it at 6,000C – as hot as the Sun’s surface. Nettet11. apr. 2024 · The data revealed that the ancient structure may cover the core-mantle boundary (CMB) beneath the surface. The findings published in the journal Science Advances state that the layer was discovered beneath a largely unsampled portion of the Southern Hemisphere.
