Verified Answer
What are extrusive igneous rocks?
Extrusive igneous rocks also known as volcanic rocks. They are formed by the cooling of molten magma on the Earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, solidifies at a faster rate. So extrusive igneous rocks are smooth, crystalline, and fine-grained.
