WebMar 31, 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.

It sits below the lithosphere, reaching from 50 miles to 120 miles below the earth's surface. The boundary where the lithosphere and asthenosphere meet is referred to as the LAB. Most of the asthenosphere is solid but could be melted depending on its location.
