Which correctly lists the three zones that further divide the open-ocean zone? O deep zone, Intertidal zone, neritic zone
noritic zone, surface zone, trench zone
doop zone, surface zone, transition zone
Intertidal zono, noritic zone, surface zone

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
