1. The process by which rocks are broken down by natural or chemical means – Weathering. This is the process where rocks are broken down into smaller pieces or minerals through natural elements like wind, water, and temperature changes, or through chemical reactions.
2. Rock formed from molten rock – Igneous rock. This type of rock is created when magma cools and solidifies, either beneath the Earth’s surface (intrusive) or after it erupts as lava (extrusive).
3. Rock formed from compressed sand and fossilized organisms – Sedimentary rock. This rock type is created from the accumulation and compaction of mineral and organic particles, often including fossils from ancient life.
4. Magma that reaches the surface of the Earth – Lava. When magma escapes from beneath the Earth’s crust and erupts, it is referred to as lava.
5. Large floating pieces of rock that move across Earth’s mantle – Tectonic plates. These are substantial sections of the Earth’s lithosphere that float on the semi-fluid asthenosphere beneath, and they move due to convection currents in the mantle.
