A popular view among geophysicists is that large amounts of water are carried from the oceans to the deep mantle in "subduction zones," which are boundaries where the Earth's crustal plates converge, with one plate riding ...

New simulations of Earth's asthenosphere find that convective cycling and pressure-driven flow can sometimes cause the planet's most fluid layer of mantle to move even faster than the tectonic plates that ride atop it.

Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus's heat flow mechanism ...

When the rigid plates that make up Earth's lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet's surface. Strike-slip faults, such as the San Andreas Fault in California ...
