An average igneous rock contains zero biological calories for living organisms, but a single cubic meter of Earth's interior can contain immense thermal energy, distinguishing the humorous question of how many calories do the rocks eat from the serious topic of Earth's geology.

Rocks are inorganic materials, completely lacking the carbon-based organic compounds like carbohydrates, fats, and proteins that provide energy for humans. Because of this fundamental chemical makeup, rocks do not have caloric value in any nutritional sense, a critical scientific fact often misunderstood.

Over 90% of the Earth's crust is composed of silicate minerals, a class of minerals built from silicon and oxygen atoms. This surprising fact highlights that while many assume minerals are a basic, singular substance, they are actually composed of even more fundamental components: chemical elements.

Did you know that every single rock you see is made of one or more minerals? Minerals are not just pretty rocks; they are the building blocks of our entire planet and are essential for both technology and our own health. In this guide, we'll explain exactly why are minerals important, grade 5 students, and reveal their incredible uses in our daily lives.
