Paleo‐temperature data indicates that the Earth's mantle has not cooled at a constant rate.
The data show slow cooling from 3.8 to 2.5 Ga followed by more rapid cooling until the …

Mantle water content estimates range from 0.5 to 15 oceans of water. Its evolution is even
more unclear. Rapid degassing during mantle solidification likely released much of the …

The Earth has remained magmatically and volcanically active over its full geologic history
despite continued planetary cooling and a lack of thermal equilibrium in the mantle. Here we …

Earth is a magmatically active planet. Magmatism connects Earth's interior to its atmosphere,
hydrosphere, and biosphere through cycling of volatiles, greenhouse gasses, and nutrients …

Paleo-temperature data indicates that the Earth's mantle did not cool at a constant rate over
geologic time. The data are consistent with slow cooling from 3.8 to~ 2.5 billion years ago …

Paleo-temperature data indicates that the Earth's mantle did not cool at a con-6 stant rate
over geologic time. The data are consistent with slow cooling from 7 3.8 to 2.5 billion years …

Plate tectonics convectively cools the Earth at present. Debate remains in defining plate
tectonics as a dynamic system. What is the primary resistor to plate motions: plates, mantle …

Water is injected into the mantle by the subducted plate and is transported by mantle
convection. The deep-Earth water circulation is expected to significantly affect the …
