Here are the steps that describe the transformations for each scenario you provided:
A. Intrusive igneous rock 🡪 sediment:
- Weathering: The intrusive igneous rock is broken down into smaller particles through physical and chemical weathering processes.
- Erosion: These particles are then transported away by wind, water, ice, or gravity.
- Deposition: The eroded materials settle in new locations, accumulating in layers.
B. Metamorphic rock 🡪 sediment:
- Weathering: The metamorphic rock is subjected to physical and chemical weathering, which breaks it down into smaller pieces.
- Erosion: The weathered material is subsequently transported by natural agents such as water, wind, or ice.
- Deposition: The sediment is deposited in new areas, contributing to sedimentary processes.
C. Sediment 🡪 sedimentary rock:
- Compaction: Loose sediment is buried under additional layers of sediment, resulting in increased pressure that compacts the particles together.
- Cementation: Mineral-rich water percolates through the sediments, precipitating minerals that act as a glue, binding the sediment grains together to form solid rock.
D. Sedimentary rock 🡪 sediment:
- Weathering: The sedimentary rock undergoes weathering processes that break it down into smaller fragments and particles.
- Erosion: These particles are then transported away by various erosion processes, including water, wind, or ice.
- Deposition: The eroded sediment is eventually deposited in various environments, accumulating layers over time.
Each transformation highlights critical geological processes that contribute to the rock cycle.
