What is the difference of a metamorphic rock and a sedimentary rock?

Answer 1

The difference of metamorphic rocks from igneous and sedimentary rocks is on the way these rocks are formed. Igneous rocks form when magma cools down and becomes solid while sedimentary rocks form due to erosion and weathering of the Earthâ??s material, whereas, metamorphic rocks are formed as a result of rock transformation called metamorphism.

Answer 2

Metamorphic rocks are rocks changed by intense heat or pressure. They are usually shinier, harder, more consolidated than the parent rock (rock before it was metamorphosed). Metamorphic rocks are often banded and/or they have crystals. HOPE THAT HELPED! :D

Answer 3

Metamorphic rocks are cause by a pre-existing rock, either igneous or sedimentary which under extremes of heat or pressure (or both) change their form. Eg Limestone (sedimentary) undergoes metamorphism to marble (metamorphic ). Sedimentary rocks are rocks that have been formed through compaction and cementation of sediments as a result of the weathering and erosion of other sedimentary rocks, metamorphic or igneous rocks. Eg. Limestone is madeup of shells, corals and other algal and or fecal matter.

Answer 4

A metamorphic rock has gone through several changes from merging to breaking to combining unlike igneous which is fresh out of the volcano & sedimentary which changed form by water or air by itself.

Answer 5

Metamorphic rocks are formed from the alteration of pre-existing rocks under high heat and pressure, while sedimentary rocks are formed from the accumulation and cementation of sediments. Metamorphic rocks have a foliated or non-foliated texture due to the recrystallization of minerals, while sedimentary rocks often have visible layers or bedding structures.

Answer 6

Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.

Answer 7

metamorphic is formed by a volcanic eruption. sedimentary is formed by the earth.
