How can an igneous rock turn into a sedimentary rock?
A. through erosion, pressure and cementation
B. through cementation, pressure and erosion
C. through heat, erosion and pressure
D. through erosion, heat and pressure
B. through cementation, pressure and erosion
The correct answer is D. through erosion, heat, and pressure.
Here is a step-by-step explanation:
1. Erosion: Weathering agents like wind, water, and ice break down the igneous rock into smaller particles or sediments.
2. Transport: The sediments are then transported by agents like rivers, glaciers, or wind and deposited in a different location.
3. Compaction: The weight of the overlying sediments exerts pressure on the deposited sediments, causing them to compact.
4. Cementation: Minerals dissolved in water fill the spaces between the compacted sediments and act as cementing agents. Over time, these minerals crystallize, binding the sediments together to form a solid rock.
5. Heat and Pressure: Overlying sediments and other geological processes can subject the sedimentary rock to heat and pressure, which can further transform it into a metamorphic rock, if the conditions are right.
