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 ...

The oceanic lithosphere forms at the summit of ocean ridges during seafloor spreading. Still, the formation of ocean basins is complex, influenced by smaller-scale convection, stagnated pieces of the lithosphere, and tectonic ...

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 ...

Subduction zones are cornerstone components of plate tectonics, with one plate sliding beneath another back into Earth's mantle. But the very beginning of this process—subduction initiation—remains somewhat mysterious ...

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.

The lithosphere ( /ˈlɪθəsfɪər/; Greek: λίθος [lithos] for "rocky" + σφαῖρα [sphaira] for "sphere") is the rigid outermost shell of a rocky planet. On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
