- Lava: When magma flows onto Earth's surface, it is called lava. ↷
- Igneous Rock: Formed through the cooling ol lava. ↷
- Sediment: A naturally occurring material that is broken down by processes of weathering and erosion, and is transported by the action of wind, water, or glaciers. ↷
- Sedimentary Rock: Sedimentary rocks are types of rock formed by depositing mineral or organic particles on the Earth's surface. This process could potentially last millions of years! ↷
- Metamorphic Rock: This rock is formed from mperatures greater than 150 to 200 °C and elevated pressure. ↺
