Detailed explanation-1: -Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Detailed explanation-2: -Limestones are formed by metamorphism of igneous rocks.

Detailed explanation-3: -Explanation: When massive amounts of heat and pressure are applied to an igneous rock, it compacts and becomes a metamorphic rock.

Detailed explanation-4: -If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock.

Detailed explanation-5: -From the Greek “to transform, ‘’ metamorphosis is the change that occurs when rocks under the earth’s surface are subjected to intense heat and pressure, turning them into metamorphic rocks. A type of extrusive igneous rock, created from lava that cools so quickly that no crystals can form on its surface.
