Description
-
The document discusses the classification and characteristics of rocks and minerals. It identifies three main types of rocks: igneous, formed from cooled magma or lava; sedimentary, created from the accumulation and compaction of materials; and metamorphic, which arise from changes in existing rocks due to heat, pressure, or chemical processes. Key properties such as color, texture, and mineral composition are vital for rock identification. Additionally, it highlights that over 95% of Earth's crust is made up of silicate minerals, emphasizing the significance of these minerals in geological studies.
