Metamorphic Rocks
As temperature rises, the energy reorganizes atoms in minerals, leading to the formation of new minerals. For example, the metamorphic rock gneiss often forms from the heating of shale or granite.

How do fossils form?
Permineralisation occurs when dissolved minerals carried by ground water fill up space inside the cells of plants and animals.The dissolved minerals crystalise in these cellular spaces and eventually form rocks in the shape of the animal or plant. This is the most common type of fossil preservation and examples include teeth, bones, shells and wood.

How Are Minerals Formed?
Minerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
