What percentage of the earth's crust is metamorphic rock?
Metamorphic rocks are created from intense heat and pressure being applied to an existing rock. The existing rock is called the protolith. They can also be formed from lava being poured over the top of the earth's surface, where rocks lay underneath. Metamorphic rocks make up a large part of our earths crust. It is around 40-60% of the earts crust.
How Metamorphic are form?
Weathered products of existing rocks are transported , deposited , compacted , and cemented.
What makes up about 95 percent of the rocks in earths crust?
Igneous and metamorphic rock make up 95% of the rocks in Earth's crust. Only a thin layer is made up of sedimentary rock.
What percentage of earth's crust is composed of igneous and metamorphic rock?
Approximately 95% of Earth's crust is composed of igneous and metamorphic rock. This includes rocks like granite, basalt, and schist, formed from the cooling and solidification of magma and the alteration of existing rocks under high heat and pressure. Sedimentary rocks make up the remaining 5% of the crust.
Is a metamorphic rock made in earths crust?
Yes, metamorphic rocks are formed in Earth's crust through the process of metamorphism, which involves the alteration of existing rocks through heat, pressure, or chemical processes. This leads to the formation of new rock types with different mineral compositions and textures.
Is most of the earths crust made up of a mix of metamorphic and igneous rock?
This is true!

Why is there no sedimentary rock deep in the earths crust?
Sedimentary rocks get transformed into metamorphic and eventually igneous rocks in deep earth's crust.
How does a metamorphic rock becomes an igneous rock?
If a metamorphic rock is buried deeply in the earths' crust it comes under great pressures and temperatures. If these are great enough to re-melt the rock it ceases to be metamorphic and when it cools, it re-crystallizes into an igneous rock.
How does a metamorphic rock turn into a igneous rock?
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.
What rock makes up most of earths crust and what percentage is it?
90 persent and lava

What two things deep beneath the earth's surface can change any rock into a metamorphic rock?
heat and pressure in the earths crust with little if any chemical change.
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
Is the crust made up of rock?
Yes. The crust is made of igneous, sedimentary, and metamorphic rock.
