When the majority of its constituents become melted then cool and solidify.
Any rock can become a metamorphic rock. To become a metamorphic rock the rock must undergo heat and/or pressure, but not so much that the rock melts. Should the rock melt it would become an igneous rock.
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
By a process of melting and re-solidification of the melt produced..
by going under heat and pressure
no lava is a liquid that when cooled forms extrusive igneous rock Metamorphic rock is something that has been "metamorphosed" usually by being shoved down into the high temperatures and pressures inside the earth by tectonic plate movement. Sandstone (soft) can become granite (hard) in this way.
A metamorphic rock can become a igneous rock by melting and cooling
Metamorphic rock can not become igneous rock, however igneous rock can become metamorphic. This process happens over time as the rocks are shifted, compressed and heated by the Earth.
Any metamorphic rock can melt and recrystallize and become an igneous rock.
A pre-existing, igneous, sedimentary and metamorphic rock.
Igneous rock can weather and become sedimentary rock . Metamorphic rock can be melted in a volcano and become igneous rock. Igneous rock and sedimentary rock can be heated and pressurized to form metamorphic rock.
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.
by melting and cooling
Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. As the lava cools it hardens and becomes igneous rock.
Metamorphic rock can melt under the surface of the earth, and the harden into an Igneous rock. As an Igneous, it could crystalize, or break down into sediment where it can become either Igneous or Sedimentary.
Any rock can become a metamorphic rock. To become a metamorphic rock the rock must undergo heat and/or pressure, but not so much that the rock melts. Should the rock melt it would become an igneous rock.
no
If it is heated.
