​ (a)   rocks makeup 90% of Earth's crust.

• Igneous
• Magma
• Metamorphic
• Sedimentary

​ (a)   Created from the cooling and solidification of magma or lava.

​ (b)   Created from the deposition of sediments in layers over long periods of time, it often contains fossils.

​ (c)   Existing rock is subjected to very high heat and pressure, usually underground.
