Obsidian is a black stone and it can be any shape or size. It is also a very hard rock. It has a hardness scale of 7. It is the 3rd hardest rock on the earth. It could be used as a road. So if you ever see obsidian you should try to break it.

Limestone is white and its coloring will stain your fingers. Limestone is a very easy rock to get rid of, all you have to do is throw it on the ground and it will break. Limestone and sand are most of what is under Florida. Sometimes this mixture added with water will create a sink-hole. A sink-hole is what happens when running water dissolves the limestone under the surface and the ground above caves in.
