Test 2 –Earth Structures, Earthquakes & River Systems
Annotate this photograph (taken earlier this semester near the Ohio River in West Virginia) by labeling the hanging wall “HW” and the footwall “FW” and marking the fault highlighted in red with shear sense arrows. (Note the offset coal seam (2 pts)
