Answer
One rock property that can quickly distinguish an intrusive igneous rock from an extrusive one is the texture. Intrusive igneous rocks typically have a coarse-grained texture, while extrusive igneous rocks have a fine-grained or glassy texture. The difference in cooling rates between the two types of rocks results in variations in crystal size, making texture an effective characteristic for distinguishing between them.
