• LITHOSPHERE
The lithosphere is the rigid outer layer of the Earth consisting of the crust and the uppermost
solid part of the mantle. It is broken into tectonic plates that move slowly over the Earth’s
surface.
• ASTHENOSPHERE
The asthenosphere is a semi-fluid, mechanically weak layer located below the lithosphere in
the upper mantle. The rocks in this layer are partially molten and capable of slow flow, which
enables the movement of tectonic plates.
