The process of transformation:
1. Weathering and Erosion: Igneous rock is exposed to the elements (rain, wind, ice, temperature changes). This breaks down the rock into smaller pieces (sediments).
2. Transportation: The sediments are carried away by wind, water, or ice to a new location.
3. Deposition: The sediments settle in a new location, usually in layers.
4. Compaction and Cementation: Over time, the weight of overlying sediment compacts the layers, squeezing out water and air. Minerals dissolved in the water precipitate between the sediments, acting as a "cement" and binding them together.
It's a Cycle, not a Direct Transformation:
The process described above is part of the rock cycle. It's a continuous process where rocks are constantly being transformed from one type to another.
So, while igneous rock doesn't directly turn into sedimentary rock, it's a key ingredient in the process. The broken-down pieces of igneous rock become the sediments that eventually form sedimentary rock.
