Answer:
Granite is coarse grained, has a uniformly dispersed crystalline structure, has a specific gravity of 2.6-2.7, is composed of varying amounts of various feldspars, quartz, micas, and other minerals, even small amounts of uranium. Granite is hard, tough, and resistant to fracture because of the interlocking structure of the minerals within. Granite's colors are varied; pinks, reds, and gray are most common.
Its porosity is negligible, between 0.3 to 4%. It's weather resistant, heat resistant and even chemical resistant.
