Tectonic plates are massive slabs of Earth's lithosphere that float atop the semi-fluid mantle, constantly shifting and ...

Convection currents have also been observed by NASA's New Horizons mission on the dwarf planet Pluto, which exhibits polygonal surface features resembling plate boundaries on Earth, according to ...

The crust of volcanically active Venus could be churning with convection currents just like the Earth's mantle.. This is the conclusion of researchers from the Washington University in St. Louis ...

Earth's solid surface, or lithosphere, extends more than a hundred miles into the planet.It's broken into large chunks, and the convection currents of molten rock below exert pressure on these ...

Pull up Google Earth and zoom out to see that the Earth has lighter and darker places. You can have students do this or do it as a class. Guiding students. Zoom in to different levels and observe the ...

Early in the days of plate tectonic theory, geologists and geophysicists assumed plates move because of mantle convection. Currents of hot, molten material rising inside the Earth push the plates ...

Global warming during the Last Interglacial period caused so much Arctic ice to melt that Atlantic currents collapsed — and scientists say these are the conditions we could be heading toward.

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting ...

On Earth, convection deep in the mantle provides the energy that drives plate tectonics. Earth’s crust, about 40 kilometers thick in continents and 6 km in ocean basins, is too thin and cool to ...
