The three types of rocks

It’s the first thing you learn in a geology class — very briefly the three types of rocks are:

Igneous — they form from the cooling of magma deep inside the earth. They often have large crystals (you can see them with the naked eye).

Metamorphic — they are formed through the change (metamorphosis) of igneous and sedimentary rocks. They can form both underground and at the surface.

Sedimentary — they are formed through the solidification of sediment. They can be formed from organic remains (such as limestone), or from the cementing of other rocks.

Now the long story, which is much more interesting, is this
