Match the rocks to their classifications.
To match rocks to their classifications, you would typically need to identify the characteristics of the rocks and their formation processes. Here are some common rock classifications and their characteristics to help you in matching them:
1. Igneous Rocks:
- Formed through the solidification of molten material such as lava or magma.
- Have a crystalline structure due to the slow or rapid cooling of molten material.
- Examples include granite, basalt, and pumice.
2. Sedimentary Rocks:
- Formed from the accumulation and cementation of sediment particles like sand, mud, or even organic material.
- Often have visible layers or stratification.
- Examples include limestone, sandstone, and shale.
3. Metamorphic Rocks:
- Formed from the transformation of existing rocks due to intense heat, pressure, or chemical processes.
- Often display foliation, which is a parallel alignment of mineral grains.
- Examples include marble, slate, and gneiss.
To match the rocks to their classifications, you would need to analyze their characteristics. Look for signs of crystal structure and interlocking grains for igneous rocks. Look for layers and sedimentary structures for sedimentary rocks. Look for foliation or changes in mineral composition for metamorphic rocks. By examining the physical properties and formation processes of the rocks, you can determine their proper classification.
