Rock Haikus

They come from inside
They were molten, now they aren’t
They are igneous

Phaneritic rocks
Large crystals live in this kind
Visible crystals

Aphanitic rocks
Small crystals you cannot see
Small, like the aphid

Silica, felsic
Light color, low density
Continental Crust

Iron rich, mafic
Darker, higher density
Oceanic Crust

Igneous rocks have
many different names we learn
Vocab is a pain
