Question

The bounding faults on the eastern side of the Great Basin are mostly down to the east, whereas the bounding faults on the western side (in eastern California and western Nevada) are down to the west.

A) Normal fault
B) Reverse fault
C) Strike-slip fault
D) Thrust fault

Answer 1

The bounding faults on the eastern side of the Great Basin are mostly down to the east, which are normal faults. On the western side, the faults are mostly down to the west, which are reverse faults.

Step-by-step explanation:

The bounding faults on the eastern side of the Great Basin that are mostly down to the east are called normal faults. An example of a normal fault is the Basin and Range province in Nevada, where basins drop down relative to the ranges on the footwall.

On the other hand, the bounding faults on the western side of the Great Basin in eastern California and western Nevada that are mostly down to the west are called reverse faults. The San Andreas Fault is a well-known example of a reverse fault.

Therefore, the correct answer is B) Reverse fault.
