Answer 2

Answer:

$\huge\frak{\underline{\underline{\red{Answer}}}}$

The four main categories of mineral formation are:

• (1) igneous, or magmatic, in which minerals crystallize from a melt,
• (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion,
• (3) metamorphic, in which new minerals form at the expense of earlier ones owing to the effects of changing—usually increasing—temperature or pressure or both on some existing rock type, and
• (4) hydrothermal, in which minerals are chemically precipitated from hot solutions within Earth. The first three processes generally lead to varieties of rocks in which different mineral grains are closely intergrown in an interlocking fabric. Hydrothermal solutions, and even solutions at very low temperatures (e.g., groundwater), tend to follow fracture zones in rocks that may provide open spaces for the chemical precipitation of minerals from solution.
