Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
Is anthracite an igneous metamorphic or sedimentary?

How are rocks classified into one of these three groups?
Rocks are classified into three groups based on how they are formed. Igneous rock is formed when magma cools and crystallizes. Sedimentary rock is formed when the products of weathering and erosion are compacted and cemented to form new rock. Metamorphic rock is formed when existing rock is changed by heat, pressure or chemical change into a new kind of rock.
What percent of rocks are metamorphic sedimentary or igneous?

What type of rocks are metamorphic rocks formed from?

The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
How are metamorphic and sedimentary igneous rocks formed?
Igneous- Formed from hot molten magmaSedimentary- formed from sediments piling up creating layersMetamorphic- Formed when intense heat AND pressure are applied to an igneous or sedimentary rock.
