Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

The emerging model of mantle convection suggests that some relatively cool subducting slabs of oceanic plate (blue) are deflected at the 660 km discontinuity (dashed black line) whereas others ...

Under the Pacific Ocean, hidden material was discovered in Earth’s mantle. So we have sunken, ancient worlds down there, and […] The post Underneath The Pacific Ocean, There Are Sunken Worlds In The ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents ... tectonic plates sink into the mantle at subduction zones.

are where tectonic plates pull apart due to convection currents in the mantle. Most constructive plate boundaries are found on ocean floors. Some of these undersea volcanoes become so large that ...

It is unlikely that the Earth's mantle — the layer beneath the crust and above the core — was completely homogeneous when it initially formed. Over time, cooling-induced convection as well as ...

Overall, Professors Sun and Tkalčić determine that mantle convection is the primary cause of Mars's unusual dichotomy, not giant impacts as the alternative hypothesis suggests. But their ...
