Well, you might be thinking from the title, who cares about rocks? I mean, they're pretty boring. I'm here to prove you wrong.
First of all, there are 3 types of rocks, sedimentary, igneous and metamorphic. The scientific study of rocks is called petrology.
Let's start with igneous, igneous comes from the word igneus. Which is Latin and means fire.
The first rock is granite, granite is an igneous rock and is just magma that cools down in the mantle of the earth.
It is a combination of quartz, feldspar and biotite materials.
There is also basalt, which is lava that has cooled outside the earth, this cools down alot quicker than granite.

Let's move on to sedimentary, sedimentary rocks are sediments that have piled on to each other and have compressed and hardened over time due to great heat and pressure to form rock.This is done over millions of years.
The main sedimentary rocks are limestone and sandstone. sandstone is the compression and hardening of sand. and limestone is the compression and hardening of bones and shells.

Metamorphic rocks are sedimentary or igneous rocks that have morphed due to changes in heat or pressure.
There are two metamorphic rocks you probably already know, marble and slate. Marble is limestone that has been morphed while slate is morphed clay.
