Convection current in the asthenosphere

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. WebSep 28, 2024 · Heat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp). These convection currents cause the tectonic plates to move several centimeters per year relative to each other. Material Lava lamp Instructions Plug in a lava lamp.
