There is a requirement for either an increase in temperature or pressure, or a combination of these two things.
igneous
gravel is a limestone which can be igneous or metamorphic but almost all is metamorphic
The process that can change an igneous rock into a metamorphic rock is called metamorphism. This occurs when the igneous rock is subjected to high temperatures and pressure deep within the Earth's crust. These conditions cause the minerals in the rock to recrystallize and realign, forming a new metamorphic rock with different physical and chemical properties.

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.
An igneous rock can be metamorphosed (changed) into a metamorphic rock but will no longer be an igneous rock. An igneous body can be intruded into metamorphic rocks but will still be an igneous rock that is different from the surrounding metamorphic rocks. Ethier answer work depending on how the question is read.
Great pressure and heat, but short of the temperature that would completely melt the rock.
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
A metamorphic rock can become a igneous rock by melting and cooling
Weathering and erosion turn igneous rock to metamorphic rock.
Any metamorphic rock can melt and recrystallize and become an igneous rock.
The metamorphic rock melts into magma then cools into igneous rock
No, metamorphic can be formed by either igneous or sedimetary rock.
Yes. A metamorphic rock can melt and the re-solidify as an igneous rock.
if the igneous rock is put under heat and pressure it turns into a metamorphic
Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.
