Accepted Answer

To determine the type of fault shown in the image, you'll want to identify the hanging wall and footwall first. 1. **Normal Fault**: The hanging wall moves down relative to the footwall. This typically occurs in areas where the crust is being extended. 2. **Reverse or Thrust Fault**: The hanging wall moves up relative to the footwall. This is common in compressional environments. 3. **Left-lateral Fault**: If you stand on one side of the fault and the opposite side moves to the left, it's a left-lateral fault. 4. **Right-lateral Fault**: If the opposite side moves to the right, it's a right-lateral fault. Based on the apparent movement of the blocks in the image, which type of movement do you observe? This will help you choose the correct answer from the options provided. What do you think?
