Oceanic crust is formed at a divergent plate boundary.
Answered by GPT 3.5
The movement of tectonic plates causes sedimentary rocks to be subjected to high temperatures and pressures, which leads to their transformation into metamorphic rocks through processes like recrystallization and foliation.
Answered by GPT 3.5
For sand to eventually become metamorphic rock, the processes of compaction and cementation must occur first, turning loose grains of sand into a solid sedimentary rock called sandstone. Then, through additional heat and pressure over time, the sandstone undergoes recrystallization and metamorphism, transforming into a metamorphic rock such as quartzite.
