For metamorphic rock to change into igneous rock, it must first melt. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock. Metamorphic rock can become molten by exposure to heat and pressure from depth of burial and compression through tectonic plate subduction, or from close proximity to a magmatic heat source.
The metamorphic rock could also become exposed to weathering, erosion, and subsequent deposition, compaction and cementation which would lead to the formation of sedimentary rock. Once again, the sedimentary rock could become molten by exposure to heat and pressure from depth of burial through tectonic plate subduction, or from close proximity to a magmatic heat source. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock.

If a metamorphic rock contains and intrusion of igneous rock which rock is the oldest?
In this scenario, the igneous rock intrusion is the youngest rock, as it formed after the metamorphic rock was already in existence. The metamorphic rock must have been present before the igneous rock intruded into it, making the metamorphic rock the oldest of the two. Thus, the metamorphic rock is the oldest in this context.
What is the name of a rock when it is formed as a result of deposits from weathering and erosion?
I think you are referring to a classification of rock called sedimentary. the other two main types are metamorphic and igneous.
What metamorphic rock is currently known as coal?
Anthracite coal is classified as a metamorphic rock. I've included two wikipedia links on this subject.
What two factors can change sedimentary rock into metamorphic rock?
Sedimentary rock can be transformed into metamorphic rock primarily through heat and pressure. Increased temperature can cause the minerals within the sedimentary rock to recrystallize, while elevated pressure can lead to foliation and changes in texture. These conditions often occur deep within the Earth's crust during tectonic activity. Additionally, the presence of chemically active fluids can also facilitate metamorphic processes.
What two processes can change a rock into a metamorphic rock?
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.

What are the two types metamorphic rock?
The two groups of metamorphic rock are foliated and nonfoliated. Metamorphic rocks can also be classified as contact and regional.
Is metamorphic rock sedimentary?
No, metamorphic rock is not sedimentary; those are two different types.

What are the two types of metamorphic rock?
The two classifications of metamorphic rock are foliated and non-foliated:1. Foliated metamorphic rock such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure. The pressure is usually related to tectonic plate collisions. Schist is another type of foliated rock that exhibits thin layering of micaceous minerals, once again due to pressure and heat. The difference between these two types of foliated rock lies in the rock from which they were derived.2. Non-foliated metamorphic rock such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks.Metamorphic rock can also be classified as regional (from broad processes such as plate tectonics) or contact (from proximity to an invading heat source).
What two things can metamorphic rock change into?
Metamorphic rock can change into igneous rock through melting and solidification, or into sedimentary rock through weathering, erosion, and lithification.
What is basalt sedimentary ignous or metamorphic?
actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
