Answer 1

cool slowly, allowing for the formation of large crystals, while extrusive igneous rocks cool quickly, resulting in small or no crystals. Intrusive rocks have a coarse texture, while extrusive rocks have a fine-grained or glassy texture. Intrusive rocks are typically formed through slow cooling of magma deep underground, while extrusive rocks form through rapid cooling of lava on the Earth's surface.
