To understand how an igneous rock can turn into a sedimentary rock, we need to understand the processes involved. Sedimentary rocks are formed by the accumulation of sediments that have been weathered and eroded from pre-existing rocks. Here is a step-by-step explanation of how an igneous rock can transform into a sedimentary rock:
1. Erosion: The first step is the erosion of the igneous rock. Erosion occurs when wind, water, or ice break down and transport the fragments of the rock. Erosion can happen over long periods of time due to factors like weathering and water movement.
2. Transport: Once the igneous rock is eroded, the rock fragments are transported by agents like rivers, streams, or glaciers. These agents of transport move the rock particles away from their original location.
3. Deposition: When the transporting agent loses energy, it can no longer carry the rock particles. As a result, the sediments are deposited and accumulate in layers.
4. Compaction: Over time, the accumulated sediments become compacted under the weight of additional deposits. The pressure from above compacts the sediments, squeezing out any remaining air or water between the particles.
5. Cementation: The final step is cementation, where minerals in groundwater crystallize and bind the sediments together. These cementing minerals act like glue, sticking the particles together and transforming them into a solid sedimentary rock.
Therefore, the correct answer is "through erosion, pressure, and cementation" as these are the processes involved in the transformation of an igneous rock into a sedimentary rock.
