@Kaitlynrick,
well, Im not going to talk down to you. With what youve lready found, tell me where you have a problem understanding , maybe I can help a little. HOWEVER, Im not looking anything up, get it?
I teach in college and dont believe that, we as teachers should be providing answers by e-mail. However I can check your efforts by acting as someone who can listen and maybe steer you.
PS, whats so diifcult about quartzite?
how do quartzite and quartz differ?
