Question

which force created a fault - block mountain?
compression
shearing
subduction
tension

Explanation:

Fault - block mountains are formed when tensional forces act on the Earth's crust. Tension causes the crust to stretch, and when the stress exceeds the strength of the rock, it fractures. Blocks of the crust then move up or down along these faults. Compression creates folded mountains (e.g., Himalayas). Shearing causes lateral movement and can lead to transform - fault boundaries. Subduction is related to the process at convergent plate boundaries where one plate is forced under another (e.g., in the formation of volcanic arcs).

Answer:

tension
