Question

Cross section of a continental collision The mountains at B are being formed by O strike-slip faulting O normal faulting O thrust faulting O subduction volcanism O All of the above. D Question 17 4 pts Which of the following statements is FALSE? O Major mountain ranges can be the product of more than one orogeny. O Mountains continue to get higher as long as the rate of erosion equals the rate of uplift. O Fault-block mountains result when blocks of crust drop downward along normal faults. O Small fragments of continental crust that are too buoyant to be subducted during convergence become exotic terranes

Explanation / Answer

1. Mountains at B are formed by normal faulting

When a mountains are formed they are getting uplifted means that mountains are extended above the reference line hence there will be only one option that is normal faulting.

Strike slip fault is formed along the strike of mountains but in the above question the whole mountain is getting higher hence this is not the answer

Thrust faulting occurs when the blocks moves in downward side. But here mountain is uplifting hence the blocks are moving upward and not downward. Hence this is not the answer.

Subduction volcanism makes some dome or cone shape structure hence this is not the answer.

2. Fault block mountains are formed when part of the crust is fall downward- it is false. True is block moves upward.

All other options are correct.

Fault block mountain
