asthenosphere
|
The hot, plastic layer of the upper mantle below the lithosphere, extending some 350 to 650 km below the surface. Convection currents within the asthenosphere power plate tectonics.
|
|
|
basalt
|
The relatively hravy crustal rock that forms the sea beds, composed mostly of oxygen, silicon, magnesium, and iron.
