There are 101 minerals that start with the letter H. From Hagemannite to Hyperalite. Minerals are naturally occurring, inorganic solids with a defined chemical composition and a crystalline structure. They are the building blocks of rocks and are classified based on their chemical properties, crystal structure, and texture. Minerals form through a variety of geological processes, including crystallization from molten rock, precipitation from solutions, and metamorphism under high pressure and temperature. They are essential not only for geological processes but also for many industrial applications and are critical for life, serving as nutrients in biological systems.

An intriguing fact about minerals is that some larval insects use mineral particles from the environment to enhance their camouflage, adapting to their surroundings for protection against predators. This innovative use of minerals demonstrates the complex interactions between organisms and their natural habitats.
