The asthenosphere

http://www.differencebetween.net/science/differences-between-the-earths-lithosphere-and-asthenosphere/ WebThe asthenosphere separates the strong, solid rock of the uppermost mantle and crust above from the remainder of the strong, solid mantle below. The combination of uppermost mantle and crust above the asthenosphere is called the lithosphere. The lithosphere is free to move (glide) over the weak asthenosphere.

The lithosphere: Facts about Earth

WebAnd so we call this process, this is convection. Now, the reason why we think the plates are moving is because we think that there are similar types of convection currents in the asthenosphere, in the mantle, in the more fluid part of the mantle. Remember, most of the mantle you can kind of view it as this mooshy, spongy, not quite liquid, but ...

WebThe mantle is not a magma. Only molten rock is called "magma". The asthenosphere is at most 2-3% molten material. The bulk of the asthenosphere is solid. However, over long time scales, solid material at these pressure and temperature conditions can behave like a liquid (even though it is not molten).
