WebMantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface.. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.The lithosphere is divided into a number of tectonic plates that are continuously … Web31 mrt. 2024 · The concept of plate tectonics was formulated in the 1960s. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 100 km (60 miles) thick and overlies a plastic (moldable, partially molten) layer called the asthenosphere. The lithosphere is broken up into seven very large continental- and ...
