How does the sedimentar rock changes to metamorphic?

Answer 1

Sedimentary rock transforms into metamorphic rock through a process called metamorphism, which occurs under increased pressure and temperature conditions, typically deep within the Earth's crust. This alteration can involve recrystallization of minerals, foliation, or the formation of new minerals, leading to a denser and more durable rock. Factors such as tectonic activity, heat from nearby magma, and the presence of fluids contribute to these changes, resulting in rocks like schist or marble from their sedimentary predecessors.
