The lithosphere is is made of dense solid material while the asthenosphere is made of liquid molten metal
The lithosphere is a mixture of gasses while the asthenosphere is made of rigid, solid rock
The lithosphere is molten rock that moves while the asthenosphere is rigid and thin
The lithosphere is made of rigid, solid rock while the asthenosphere is a softer hot rock that flows.

An earthquake occurs along a fault when:
Stress in the rock along the fault does not change for a long period of time
Stress in the rock along the fault causes the rock to melt
