Question

the image is of the formation of a fault - block mountain. which of these most likely occurs to result in the formation of these mountains? the crust is compressed. the crust does not spread apart. the center block is forced upward. the hanging walls from the two parallel faults slip down. hanging wall normal faults hanging wall

Explanation:

Fault - block mountains form when normal faults break the crust into blocks. The center block is forced upward relative to the blocks on either side. Compression is more related to fold - mountains. The crust does spread apart in the formation of fault - block mountains, and it's the center block rising, not just the hanging walls slipping down that is the main cause of the mountain formation.

Answer:

The center block is forced upward.
