Can igneous rock contain crystals
WebIgneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidifies and can form extrusive igneous … WebIgneous rocks are composed of interlocking crystals, while sedimentary rocks are composed of numerous layers of various materials. Metamorphic rocks have a deeply interlocked structure that is the result of numerous transformations that have occurred over time. The structure of rocks also affects their hardness and durability.
