both are correct metamorphic rock can form from both.
There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)
composition, how it is formed
Igneous, metamorphic, and sedimentary are the three types of rocks. Sedimentary is formed when layer of mud or silt build up gradually. Igneous is formed when molten magma cools. Metamorphic is formed when a type of rock changes to another type
Gneiss is a metamorphic rock formed from either igneous or sedimentary deposits.
there are 3 types of rocks- Igneous Rocks, Sedimentary Rocks, and Metamorphic RocksThere are three main type of rocks in the world. The names are Igneous, Sedimentary, and Metamorphic.The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary.
metamorphic
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.

It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
composition, how it is formed
yes
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
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.
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
igneous metamorphic and sedimentary
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
