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.
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.
If a metamorphic rock were to reach the mantle and melt, it would become magma. If that magma were then to recrystallize it would be an igneous rock.
Usually it is sedimentary rock that is changed into metamorphic - however it is entirely possible for igneous rock to become metamorphic as well. Metamorphic means different form, and in the geological since it mean rock that has been changed by heat and pressure. Now there isn't too much that can be done to igneous rock to change it chemically, by heat and pressure. But it can undergo physical distortions.
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.
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.

If it is heated.
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.
If a metamorphic rock were to reach the mantle and melt, it would become magma. If that magma were then to recrystallize it would be an igneous rock.
