[BWS.06] The graph below shows the changes in the temperature of ice when it is heated from -20 °C to 100 °C. Heat curve for ice. The graph shows the changes in the temperature of ice when it is heated from negative 20 degrees Celsius to 100 degrees Celsius. Based on the graph, which of these conclusions is correct?

Change of state takes place in portions BC and DE.

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.
