At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

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

Whether convection in the Earth's mantle extends through its entire depth or if the mantle is layered has long been debated. Recent research suggests that spatially and temporally intermittent or ...

Two Buried Supercontinents Under Africa and the Pacific Ocean Could Be Much Older Than Previously Assumed Earth has several ...

Exactly what drives plate tectonics is not known. One theory is that convection within the Earth's mantle pushes the plates, in much the same way that air heated by your body rises upward and is ...

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Convection in a liquid Convection in a liquid can be seen ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

Therefore, they do not take part in mantle convection (the flow in the Earth's mantle). Thus, contrary to what the geography books teach us, the mantle cannot be well-mixed either. Talavera-Soza ...

Mars has northern and southern hemispheres like Earth, but their defining characteristics ... and consequently experiencing more vigorous convection. "Experimental data correlating seismic quality ...
