1. Well I was going to say diorite... oops. The image says gabbro. The same image is also in our binder lol
2. calcium rich plagioclase feldspar, augite, small amounts of olivine and pyroxene
3. mafic
4. plutonic, basalt
5. i'm not sure.... i could only find that it was named after a town in tuscany, italy.
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, freshwater, and more experiments, yay again!
Now I know stuff about oceanography, saltwater, and birds, yay for the third time!
