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.

With over 5,000 officially recognized mineral species on Earth, it's a common question: what is the ultimate source of minerals? The answer is a dynamic and multifaceted geological process, driven by the planet's internal heat and surface forces, leading to constant mineral creation and recycling.

Over 66% of the Earth's continents are covered in sedimentary rock, a product of weathered and eroded materials. This remarkable statistic hints at a fundamental geological truth: minerals, while stable under certain conditions, absolutely break down when exposed to the Earth's surface. This process, known as weathering, drives the continuous reshaping of our planet's crust and is a key part of the rock cycle.

Over 6,000 mineral species are currently recognized by the International Mineralogical Association, each possessing a unique set of properties. This diversity raises the central question of how are minerals different from each other, which geologists answer by examining intrinsic chemical composition and crystal structure.

Despite appearing permanent, minerals are finite resources, and their slow but constant destruction is a fundamental geological process. Over eons, weathering, erosion, and chemical alteration work to break down and transform minerals and the rocks they compose, a natural cycle often accelerated by human intervention.

Minerals are the foundational building blocks of our planet, with over 5,300 known species. From the gleaming gemstones in jewelry to the industrial materials in our electronics, understanding these natural substances is key to grasping Earth's structure and the resources we rely on.
