질문 about instructive igneous rocks?

I also had to make a presentation on types of rocks last year! so i had some information! don't know if this helps 당신 또는 not :


Intrusive rocks come from magma. They cool slowly deep in Earth's crust. When magma cools underground, the crust acts like a blanket, insulating it, keeping it warm longer. Because the magma cools slowly, crystals of different minerals have time to grow. The molecules in the magma have time to arrange themselves into crystal formations before the magma hardens. Intrusive rocks have large crystals that can be seen with the naked eye.....


Your choice of El Captain is pretty cool!~
