Fault lines are lines of weakness in a plate and that instability results in plates shifting which can create brilliant mountain ranges. Fault lines can cause earthquakes which cause destruction to land and structures. For this lesson in our Mineralogy main lesson block, I prepared a lesson that wasn't specifically in the curriculum, though the study of mountain formation was previously addressed. When learning about mountain formation, we examined fault block mountains and fold mountains (and volcanic and dome mountains), which are formed when the plates either pull apart (divergent boundary) or when they come together (convergent boundary). When studying fault lines we find these described as Dip-Slip faults with normal faults at divergent plates and reverse and thrust faults at convergent plates. We included Strike-Slip faults both right-lateral and left-lateral, and while these faults are not responsible for mountain building, the are responsible for the transverse mountain range of southern California when a series of fault lines intersect.
