I had posted this question before but no one answered for half and hour. I finished the first question i posted but i am stuck on this one:
A rock that contains a cavity filled with crystals is called a geode. Why are the cyrstals in the middle of the geode larger than the crystals toward the outside?
Science EASY HELP -
Maybe because the inside took longer to cool, thus giving the crystals more time to grow larger.
