what is it
A piece of granite can be changed from an igneous rock to a sedimentary rock, and then to a metamorphic rock as it gets buried deeper within the Earth's crust.
El Capitan in Yosemite
No El capitan is in Yosemite. It is the largest exposed piece of granite in the world.
This is not necessary as the granite is only a small piece and is in a well ventilated area. You would need several tons of granite to emit enough radon to be concerned about and it would have to be in an enclosed area with little ventilation.
If you can find an open piece of dirt, you can find rocks. All rocks fallinto those three categories. If you find a flat, smooth piece of rock, you might have found slate, a metamorphic rock. However, most metamorphic rocks are hard to find in the New York area, as there are few plate tectonics in these parts. Anyhow, look for rocks and use this rock key: http://www.rockhounds.com/rockshop/rockkey/index.html

It gets weathered into sediment or it could be subjected to heat and pressure and become a metamorphic rock, or it could melt into magma and cool into an igneous rock.
To get it from the mine, you use a pickaxe. To cut it into smaller pieces, you use a chisel on a larger piece of granite. Or, if you have a chisel in your toolbelt, just click on the piece of granite.
Granite already is an igneous rock.
no
There are granite deposits underground spread out, and together it would be bigger.

The density of a piece of granite with a volume of 340 cm and mass of 918 g would be 1,400 grams. This is a math problem.
No it was usually carved from a piece of granite
The mineralogist tripped on a piece of granite and broke his nose.
An obelisk is made from a solid piece of grey or pink granite.
If you are looking for long lasting countertops that stand up to anything, yes they are worth it. Some argue that tile is just as durable as granite but the one piece granite is often stronger.
