Final Answer:
| What type of rock is it? | How does this rock form? | What are the characteristics of this type of rock? | Where can you find this type of rock? | Examples |
|--------------------------|---------------------------|----------------------------------------------------|----------------------------------------|----------|
| Igneous | From cooled and solidified magma or lava | Hard, grainy, often has crystals; may be light or dark colored | Near volcanoes, underground (intrusive), or on Earth’s surface (extrusive) | Granite, basalt, pumice |
| Metamorphic | From existing rocks changed by heat, pressure, or chemicals | Often layered or banded; crystals may be aligned; harder than original rock | Deep underground, especially in mountain ranges or near tectonic plate boundaries | Marble, slate, gneiss |
| Sedimentary | From layers of sediment (sand, mud, shells) pressed and cemented together | Usually has layers (strata); may contain fossils; often soft or crumbly | Riverbeds, lakes, oceans, deserts, and exposed rock layers at the surface | Sandstone, limestone, shale |
