If this isotope record reflects the temperature-dependent equilibrium fractionation of 18 O and 16 O between silica and seawater, then this would imply mean surface temperatures around 70 ± 15 °C at 3.3 Ga ( 2 ).

Just like oxygen isotopes, the carbon isotope with more neutrons (C 13) is heavier, whereas C 12 is lighter. Throughout Earth’s history, the amount of C 12 and C 13 in the atmosphere and in the oceans has changed, which ...
Webb17 jan. 2024 · For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. The new findings also challenge the theory that underwater mountain ...
