Granite is very resistant to fracture because of its interlocking mineral crystal structure.
nicknamed "The Granite State"
No. However, crystal can frequently be found in granite. This is due to the fact that both can be formed under similar circumstances, (i.e. extreme heat and pressure).
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
Granite is a heterogeneous substance. This is due to the fact that it does not appear to be consistently made of one material. An example of a homogeneous substance would be water.
Absolutely not. Granite, like most Rocks and Minerals, is not flammable AT ALL. If fact, only a very select few rocks or minerals are flammable, most simply melt. Though don't worry about granite melting, melting point is at 1215-1260 oC!
