I understand that it’s made up of minerals but what is in the minerals?
I just can’t put my finger on it, what is that igneous stuff made of, and are the metamorphic rocks made of the same thing??
In: Earth Science
The minerals in the rock vary depending upon where they have come from, so some rocks are formed from crushed seashells others from compacted sand. Under heat and pressure these rocks can then physically or chemically change into other rocks.
