compaction and cementation
compaction and cementation
cooling
heat and pressure
The correct answer is: heat and pressure
A model of the rock cycle should show the process that changes sedimentary rock to metamorphic rock as heat and pressure. Heat and pressure are the main agents responsible for transforming sedimentary rock into metamorphic rock.
To understand this concept, it is helpful to have some background knowledge about the rock cycle. The rock cycle is a continuous process by which rocks are formed, broken down, and transformed into different types of rocks over time. It involves various geological processes, such as weathering, erosion, deposition, compaction, cementation, heat, and pressure.
In the case of transforming sedimentary rock into metamorphic rock, it typically occurs in the deeper layers of the Earth's crust where temperatures and pressures are high. As sedimentary rock is buried beneath the Earth's surface, it is subjected to increasing heat and pressure. These external forces cause the minerals within the sedimentary rock to recrystallize and rearrange, forming new mineral structures and textures characteristic of metamorphic rocks.
Therefore, to accurately depict the process of changing sedimentary rock to metamorphic rock in a model of the rock cycle, it should include heat and pressure as the key factors involved.
