GENERAL GEOLOGY

Detailed explanation-1: -These huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared. Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks.

Detailed explanation-2: -The metamorphic rocks too cannot be broken easily as they are formed from heat and pressure. The metamorphic rocks too cannot be broken easily as they are formed from heat and pressure.

Detailed explanation-3: -Most of metamorphic rocks have good crystallization, compact textures, high strength, small porosity, and low water permeability. Some metamorphic rocks, such as marble and quartzite, can be well considered as homogeneous isotropy.

Detailed explanation-4: -Detailed Solution. The correct answer is Limestone. Limestone is not a Metamorphic rock.
