obsidian
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
What conditions lead to the formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
Is volcanic rock only igneous?
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.

Why do igneous rocks that cool from magma underground cool so slowly?
They are surrounded by hot rock and are insulated by the surrounding material. Rocks are poor conductors of heat.
Some extrusive igneous rocks such as obsidian are glassy because they are what?
