ROCKS AND MINERALS
A rock is a solid natural object composed of minerals. 
Some rocks contain only one mineral while others
contain many minerals. 
Metals are found in the rocks in the form of 
minerals.

Rocks are like mixtures of minerals, and each rock has its own
special blend of properties like what minerals it has, how big the
grains are, and how it feels. 
We use different systems to group rocks based on their
characteristics. In nature, rocks aren't always simple and 
can have variations in their properties depending on how 
closely we look at them.

Rocks can be classified into three main types
based on how they are formed:
Igneous Rocks
Sedimentary Rocks
Metamorphic Rocks

Imagine a volcano erupting with lava everywhere.
Pretty cool, right? Well, that’s where Igneous
Rocks come into the picture. These rocks are
formed from magma or lava - that’s the super hot
liquid rock - cooling down and hardening. They
can be found deep inside the Earth or right on the
surface. The colors, textures, and sizes of these
rocks depend on how fast they cool down.
