Question

use the drop - down menus to correctly identify the type of fault in each diagram.

Explanation:

• Normal Fault: In a normal fault, the hanging wall moves down relative to the footwall. This occurs due to tensional forces in the Earth's crust. Looking at the first diagram, the movement of the blocks (with one going down relative to the other) aligns with the characteristics of a normal fault.
• Reverse Fault: A reverse fault is the opposite of a normal fault. Here, the hanging wall moves up relative to the footwall, and it is caused by compressional forces. In the second diagram, the upward - movement of one block (the hanging wall) relative to the other (the footwall) is consistent with a reverse fault.
• Strike - Slip Fault: In a strike - slip fault, the movement of the Earth's crustal blocks is horizontal, parallel to the fault plane. In the third diagram, the horizontal movement of the blocks (side - to - side) is characteristic of a strike - slip fault.

Answer:

1. Normal fault
2. Reverse fault
3. Strike - slip fault
