Question

Which of these would BEST explain a piece of metamorphic rock that was formed from a 5000 kg igneous rock under extreme heat and pressure?

A) Metamorphic rock cannot form from igneous rock under any conditions.
B) The new metamorphic rock would have a much larger mass than the igneous rock.
C) The new metamorphic rock would have a much smaller mass than the igneous rock.
D) The new metamorphic rock would have the approximate same mass as the igneous rock.

Answer 1

D) The new metamorphic rock would have the approximate same mass as the igneous rock.

Explanation:A metamorphic rock is a type of rock formed under a high temperature of above 150-200 degrees and pressure of over 1000bar, this process of Subjecting certain rock types to very high temperature in order to lead to the formation of a new Rick known as metamorphic rock is called METAMORPHISM. example inclutes

Granulite,slate, marble etc.

Igneous rocks are rocks formed as a result of the solidification of molten magma.
