6. How do minerals form? Minerals from cool solutions
Water can only hold a certain amount of dissolved solids
Minerals from hot solutions
Hot fluid flow through cracks in Earth’s crust
Minerals from magma
Magma = molten rock stored beneath Earth’s surface
Lava = molten rock erupts on Earth’s surface
Minerals form when lava cools
