Rocks
First of all there are a lot of types of rocks there are the Igneus rocks, the Sedimentary rocks, and the Metamorphic rocks.
IGNEUS The Igneus rocks are the oldest type on Earth. The word Ingneus is greek for "fire". The Igneus rocks are magma that has been cooled. Some Igneus rocks do not cool down the same way though, and that is why not all look the same. The other ones cool deep under the Earth's surface and these ones are called Intrusive, and Granite is one of these. The 5 other main types of Igneus rocks are Gabbro, Rhyolite, Basalt, Obsidian, and Scoria.
SEDIMENTARY The surface of the Earth has always been and always will be eroding. That means that bits of rock are falling apart. The rocks fall and tumble, float along rivers and over time end up with a bunch of other eroded rocks. They get compressed together and that makes them Sedimentary.
METAMORPHIC Metamorphic rocks are rocks that change shapes, with a bit of time they can go from round to being very abnormal shaped. They change thier shapes by being subjected to temperatures up to 200 degrees celcius and pressure up to 1500 bars.
