The heat from the Earth's core causes convection currents in the mantle. In this process, hot material rises, cools down as it nears the crust, and then sinks again, creating a continuous cycle ...

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 ...

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 ...

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 ...

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.
