rock formation

Rock formation is the process by which rocks are created and change over time through natural geological activities. It begins with minerals or organic materials compacting and solidifying, forming igneous, sedimentary, or metamorphic rocks. Igneous rocks cool from molten magma or lava; sedimentary rocks develop from sediments compacted over time; metamorphic rocks result from existing rocks reshaped by heat, pressure, or chemically active fluids. These processes shape the Earth's crust, often gradually, involving earth movements, weathering, and erosion, which continually transform and recycle rocks across geological eras.
