Intrusive vs. Extrusive Igneous Rocks
Let's take a look at how intrusive and extrusive rocks differ, focusing on the following aspects: what the rocks form from, where they are created, the rate of cooling, the size of crystals, and the texture of the rock.
Created from lava
Created from magma
Form on the surface where molten rock has flowed
Form inside the Earth, where it is similar to an oven, slowing the rate of cooling
Cool quickly because the lava flows on the Earth's surface or may even come in contact with wate
Cool slowly
May have very small crystals (smaller than one millimeter) or no crystals at all, often resultin
Often have a glassy texture due to rapid cooling
Examples include basalt and obsidian
Can contain vesicles or gas bubbles
May exhibit columnar jointing due to cooling and contraction
Common examples include granite, diorite, and gabbro
May have large crystals (larger than one millimeter) due to slow cooling
Can form plutons, batholiths, and dikes
Often exhibit a phaneritic texture with visible crystals
May contain minerals such as quartz, feldspar, and mica
