Question

which forms as a result of compressional stress?
anticline and syncline
normal fault
strike - slip fault
fault - block mountain

Explanation:

Compressional stress causes rock layers to bend. Anticlines are upward - arching folds and synclines are downward - curving folds, formed due to compressional stress. Normal faults form from tensional stress, strike - slip faults from shear stress, and fault - block mountains from tensional stress that causes blocks of rock to move up or down along faults.

Answer:

anticline and syncline
