Answered by GPT 3.5
The movement of tectonic plates causes sedimentary rocks to be subjected to extreme heat and pressure, which leads to the recrystallization of the minerals within the rock, transforming them into metamorphic rocks.
Answered by GPT 3.5
For sand to eventually become metamorphic rock, the process of lithification first occurs as the sand grains are compacted and cemented together. Then, with the application of increased heat and pressure deep underground, the sand undergoes recrystallization, transforming into metamorphic rock.
