Mathemagician’s Personal Rock
May 8, 2016
My rock is yellow, grey, black, and brown. It looks like a piece of pizza in its shape. It is 7 centimeters long and 3 wide. It has holes in it. I think it might be carbonatite, which is a kind of igneous rock. That means it used to be inside a volcano. It came outside of a volcano as lava and cooled.
Here I am at Lake Champlain exploring more rocks!
