An igneous rock can turn into a sedimentary rock through erosion, heat and pressure.
To understand how an igneous rock can transform into a sedimentary rock, we need to look at the processes involved. Igneous rocks are formed when magma cools and solidifies. Sedimentary rocks, on the other hand, are formed through the accumulation and consolidation of sediment.
The correct process for transforming an igneous rock into a sedimentary rock is through erosion, pressure, and cementation. Here's how it works:
1. Erosion: Over time, weathering processes, such as wind, water, or ice, break down the igneous rocks into smaller fragments called sediment. These sediments can include particles of various sizes, such as sand, silt, and clay.
2. Pressure: As sediment accumulates, it gets deposited in layers. Over time, the weight of the overlying sediment causes the lower layers to become compacted. The pressure from the weight of the layers above compacts the sediments, squeezing out any remaining air or water between the particles.
3. Cementation: As the compacted sediments undergo further burial, the minerals present in groundwater can act as cementing agents. These minerals crystallize and bind the sediment particles together, forming a solid rock. Common cementing minerals include calcite, silica, and iron oxides.
So, the correct answer is: An igneous rock can turn into a sedimentary rock through erosion, pressure, and cementation.
