Final answer:
Rocks can be distinguished from each other based on their shape, density, chemical composition, and color.
Step-by-step explanation:
Rocks can be distinguished from each other based on various characteristics:
- Shape: Rocks can have different shapes such as rounded, jagged, or smooth.
- Density: Different types of rocks have different densities. For example, igneous rocks like granite are generally denser compared to sedimentary rocks like sandstone.
- Chemical Composition: Each type of rock has a different chemical composition. This can be determined by analyzing the minerals present in the rock.
- Color: Rocks can vary in color due to different minerals and impurities present in them.
