What should a model of rock cycle show as the process that changes sending Arie rock to metamorphic rock?
A model of the rock cycle should show the process of changing sedimentary rock to metamorphic rock through metamorphism. This process involves the following steps:
1. Sedimentation: Sediments such as sand, silt, clay, and organic materials accumulate and undergo compaction and cementation to form sedimentary rock over time.
2. Burial and Heat/Pressure: The sedimentary rock gradually gets buried deeper into the Earth's crust due to tectonic forces. As it gets buried, it experiences increased temperature and pressure.
3. Metamorphism: The increased temperature and pressure induce changes in the sedimentary rock's mineral composition, texture, and structure. The rock undergoes recrystallization, where minerals may reorganize or grow larger, resulting in the formation of metamorphic rock.
4. Transformation into Metamorphic Rock: The metamorphic rock can display various textures, such as foliated or non-foliated, depending on the intensity of heat and pressure. Foliated textures have a layered or banded appearance due to the alignment of minerals, while non-foliated textures lack this alignment.
Thus, a model of the rock cycle should demonstrate how sedimentary rock undergoes metamorphism, resulting in the formation of metamorphic rock with different mineral compositions and textures.
