1. Granite: Granite is a common type of intrusive igneous rock that forms from the slow cooling and solidification of magma deep within the Earth's crust. As magma rises towards the surface, it cools and crystallizes, forming large interlocking crystals of minerals such as quartz, feldspar, and mica.
2. Sandstone: Sandstone is a sedimentary rock that forms from the accumulation and cementation of sand grains. Over time, layers of sand are deposited in rivers, lakes, or oceans, and as more sediment is added on top, the weight and pressure cause the grains to compact and cement together, forming solid rock.
3. Marble: Marble is a metamorphic rock that forms from the recrystallization of limestone under high temperature and pressure. When limestone is subjected to these conditions, the calcite crystals in the rock reorganize and grow larger, resulting in a harder, more durable rock with a characteristic veined appearance.
4. Basalt: Basalt is a fine-grained extrusive igneous rock that forms from the rapid cooling of lava on the Earth's surface. As lava erupts from volcanoes and flows across the landscape, it cools quickly, preventing large crystals from forming and resulting in a dense, dark-colored rock composed mainly of minerals such as pyroxene and plagioclase.
5. Slate: Slate is a metamorphic rock that forms from the low-grade metamorphism of shale or mudstone. Under heat and pressure, the clay minerals in these sedimentary rocks recrystallize into a dense, foliated rock with a smooth, flat surface that is commonly used for roofing and flooring.
