Question

Which major type of rock is most likely to experience brittle deformation?


metamorphic rock


sedimentary rock


igneous rock

Answer 1

Igneous rock is the major type of rock that is most likely to experience brittle deformation. This is primarily due to the fact that igneous rocks are formed from the solidification of molten material, which tends to create a more rigid and less ductile structure compared to sedimentary and metamorphic rocks. Brittle deformation occurs when rocks break or fracture under stress rather than deforming plastically.
