Does sedimentary rock become metamorphic rock after millions of years?
Yes, sedimentary rock can undergo metamorphism to become metamorphic rock over millions of years due to high temperatures and pressures deep within the Earth's crust. This process can cause the minerals in the sedimentary rock to recrystallize and form new minerals, resulting in a metamorphic rock with a different texture and mineral composition.
Is coal metamorphic?
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
What type of rock takes the longest to form?
Metamorphic rocks typically take the longest to form, as they are created from existing rocks that undergo extreme heat and pressure over long periods of time in the Earth's crust. This process can take millions of years to transform the original rock into a metamorphic rock.
What metamorphic rock is commonly known as coal?
Anthracite is a metamorphic rock commonly called coal ,whose protolith or parent rock is bituminous coal.
Who is correct a metamorphic rock is formed from a sedimentary rock or a metamorphic rock can form from an igneous rock?
A metamorphic rock can form from either a sedimentary rock or an igneous rock. When subjected to high heat and pressure, existing rocks can recrystallize and change into new types of rocks, resulting in the formation of metamorphic rocks.
Does sedimentary rock become metamorphic rock after millions of years?
Yes, sedimentary rock can undergo metamorphism to become metamorphic rock over millions of years due to high temperatures and pressures deep within the Earth's crust. This process can cause the minerals in the sedimentary rock to recrystallize and form new minerals, resulting in a metamorphic rock with a different texture and mineral composition.
Sedimentary rock becomes metamorphic rock after millions of years True or False?
It must be false, because the statement in question is not valid all the time. Sedimentary rock might become metamorphic rock after millions of years, but it might take less time, more time, or not happen at all.
How long does it take for each type of rock to form?
Igneous rocks can form quickly in days to months from cooling magma, sedimentary rocks can take hundreds to millions of years from weathering and deposition of sediments, and metamorphic rocks can form over millions of years from existing rocks under high heat and pressure.
Can metamorphic rock form out of other metamorphic rock?
No.
Is coal metamorphic?
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
What are the steps needed to form metamorphic rock from magma?
To form metamorphic rock from magma, first magma must intrude into existing rock layers. The heat and pressure generated by the magma will cause the surrounding rocks to recrystallize and change mineral composition, transforming into metamorphic rock. This process occurs deep within the Earth's crust and can take millions of years.
What type of rock takes the longest to form?
Metamorphic rocks typically take the longest to form, as they are created from existing rocks that undergo extreme heat and pressure over long periods of time in the Earth's crust. This process can take millions of years to transform the original rock into a metamorphic rock.
How does metamorphic rock become molten material?
metamorphic rocks become molten when over millions of years of compaction they come in contact with the magma which melts the rock and if near a volcano the volcano will remove it forming a igneous rock when cool

What type of rock is anthracite coal?
Anthracite coal is a type of metamorphic rock that is formed from the compression of plant material over millions of years. It has a high carbon content and a lustrous appearance, making it a valuable source of energy.
Can heat form an igneous rock or a metamorphic rock?
metamorphic because it melts the rock and forms another
