Metamorphic Rocks from Heat and Pressure by annilyn is a document available to read on EtoBox.

Rocks are naturally occurring solid masses formed by minerals and mineraloids. They are categorized based on their mineral composition, chemical makeup, and formation process. The three main types of rocks are igneous, formed by cooling magma; sedimentary, formed by accumulation of sediments; and metamorphic, formed from existing rocks subjected to heat and pressure.
