9 Ιουλ 2023 · Igneous, sedimentary, and metamorphic rocks are the three types of rocks. Rocks fall into one of these categories depending on how they form and are then further subcategorized according to formation, composition, and other properties.
Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed.
Rocks are naturally occurring solid aggregates or masses of minerals, mineraloids, or organic material that make up the Earth’s crust. They are composed of one or more minerals, which are crystalline solids with a specific chemical composition and a defined atomic structure.
