Types of Rocks
Rocks, the fundamental building blocks of the Earth's crust, are classified into three primary types: igneous, sedimentary, and metamorphic. Each type offers unique insights into the geological history and processes shaping our planet. Igneous rocks form from the cooling and solidification of molten material, sedimentary rocks originate from the accumulation and compression of sediments, while metamorphic rocks arise from the alteration of pre-existing rocks under intense heat and pressure. Understanding the distinct characteristics and formation processes of these rock types provides crucial insights into Earth's dynamic geological processes and its rich history.
