Lava flows are typically finer grained than intrusive igneous rocks. Why?

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.

The extrusive magma cools quickly so the mineral grains do not have time to grow.

The extrusive magma, because it is deep below the surface, cools very slowly producing very small mineral grains
