Geocache Description:

 This earthcache is outside Questacon on the granite sphere.


How is it formed?
Granite is the most common rock type on the continental land masses.
Granite is formed deep in the earth when magma cools very slowly. So unlike basalt the minerals have plenty of time to grow which results in the crystals and mineral grains being very visible, much coarser and textured than basalt.
Granite is 25%-35% quartz, 50%-65% feldspar and 1%-10% mica.

What is it used for?
Granite is used for bridges, tiling, monuments, bench tops, public seats and granite spheres. It can be found in some form in almost every city in the world.

Granite spheres
Granite spheres are made by sand blasting a basin in a rectangle of rock and sand blasting a perfect sphere to fit into it. Then water is pushed up to hold the sphere up. The ball can then be spun easily.

To log a find on this earth cache you must answer the following questions and email the answers to me.
1). What are the 3 main colours on the granite sphere?
2). What is the weight and diameter of the sphere?
3) What is the country of origin of the sphere?
4). Explain roughly how the ball is held up?
5). Where else is this theory used?
