Granite is a igneous rock commonly found in nature and often used in the construction business. Pieces of granite are generally large and very hard until broken up into smaller chunks. Because it is such a common rock, it is encountered often and has been used for various reasons in the past.
Color
The color of granite varies depending on the composition and specific mineralogy of the rock. These colors range from pink, to various shades of gray, to black.
Geography
Granite is common all over the world where it is a part of continental crust. Certain areas are more well known for commercial granite harvesting, such as Brazil, Norway, India, parts of Spain and certain regions of the United States.
Radioactivity
Like most natural stones, granite is radioactive, though it happens to have a higher count of uranium than rocks such as limestone. However, it still does not pose an acute health risk to humans.
Uses
In ancient times, granite was used to create architectural structures, such as the Red Pyramid of Egypt. Today, it is also used in construction, and is common for floor tiling and kitchen countertops as well.
Rock Climbing
Granite rocks are highly sought after by amateur and professional rock climbers alike. This is because of their friction and the natural cracks that form in the rock, making great hand a footholds.
