Earth Science The three primary types of rocks—igneous, sedimentary, and metamorphic—are classified by the United States Geological Survey based on their distinct formation processes involving cooling magma, accumulating debris, or intense heat and pressure.

Metamorphic rocks are formed when existing igneous, sedimentary, or even other metamorphic rocks are transformed by intense heat, extreme pressure, or chemically active fluids deep within the Earth’s crust. This process, known as metamorphism, changes the rock’s physical and chemical properties without actually melting it if the rock were to melt, it would become igneous rock instead.…

The Earth functions as a massive recycling plant where the lithosphere is constantly being reshaped through the rock cycle. This journey often begins with igneous rocks, which form from the cooling of molten material. When magma cools deep underground, it creates intrusive rocks like granite; if it erupts as lava and cools on the surface, it forms…
