What should a modelnod the rock cycle show as the process that changes sedimentary rock to metamorphic rock
A model of the rock cycle should show the process of changing sedimentary rock to metamorphic rock as follows:
1. Weathering: The model should depict the breaking down of sedimentary rock by physical, chemical, or biological processes. This can include the action of wind, water, ice, or plant roots.
2. Erosion and Transportation: The model should illustrate how the broken-down sedimentary rock particles are carried away by wind, water, or ice, and transported to new locations.
3. Deposition: The model should show the deposition of these transported sedimentary rock particles in layers, forming new sedimentary deposits.
4. Lithification: The model should demonstrate how these layers of sedimentary deposits undergo compaction and cementation over time, transforming them into sedimentary rock.
5. Burial and Heat/Pressure: The model should illustrate the process of burial of sedimentary rock layers under additional sediment, which increases the pressure and temperature.
6. Metamorphism: The model should show how the increased pressure and temperature cause the mineral composition and texture of the sedimentary rock to change, transforming it into metamorphic rock.
It's important to note that the rock cycle is a continuous process, and the model should highlight that the newly formed metamorphic rock can then be subjected to weathering, erosion, transportation, and deposition, starting the cycle anew.
