Granite is the ultimate silicate rock. As discussed elsewhere in greater detail, on average oxygen and silicon account for 75\% of the earth’s crust. The remaining 25\% is split among several other elements, with aluminum and potassium contributing the most to the formation of the continental granitic rocks.

Mineral particles sink into the sea floor where they are compacted into sedimentary rocks. Heat from molten rock changes surrounding sedimentary and igneous rock into metamorphic rock.
Why are rocks so interesting?
Geologists study rocks because they contain clues about what the Earth was like in the past. We can assemble a historical record of a planet and trace events that occurred long before humans roamed our planet.
Can rocks melt?
It melts. The same thing happens to a rock when it is heated enough. Of course, it takes a lot of heat to melt a rock. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
How long does a rock live?
Real live rock can be decades old, although dry rock can support life after a couple of months. I’d personally use mainly dry rock and only a few kg of live rock. Maybe a kg of live rock for every 5-10 kg of base rock.
