Extrusive igneous rocks are typically finer grained than intrusive igneous rocks. why? extrusive igneous rocks are typically finer grained than intrusive igneous rocks. why? the extrusive magma, because it is deep below the surface, cools very slowly producing very small mineral grains. the extrusive magma cools quickly so the mineral grains do not have time to grow. intrusive magma is cooler because it is well insulated by the surrounding rock. intrusive magma flows onto the earth's surface and cools very slowly, allowing many small mineral grains to grow.
