Here's why:

* Rocks are made of minerals: Think of minerals like the individual ingredients in a recipe. When these minerals combine in different ways, they form the various types of rocks we see.

* Different minerals, different rocks: The specific types of minerals present in a rock determine its properties like color, texture, hardness, and even how it breaks.

* From tiny crystals to massive formations: Minerals can exist as tiny crystals or as large, visible chunks. No matter the size, they are the fundamental components of rocks.
