in the ocean, how does water temperature change as depth increases?
o
a. water temperature decreases with depth.
b. water temperature increases and then decreases with depth.
o c. water temperature increases with depth.
o d. water temperature decreases and then increases with depth.

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.
