What is the main type of energy to help convert rocks into metamorphic rocks?
The melting and cooling of a metamorphic rock will allow it to turn into an Igneous rock.
Can metamorphic rocks be created by melting?
Nope, because they are created when the Earth pressurizes and heats it (but not to the point of melting). Igneous rocks are created when rocks melt.

The melting and cooling of a metamorphic rock will allow it to turn into an Igneous rock.
Does melting rocks cause earthquakes?
no
What rocks result from heat and pressure melting into magma?
sedimentary rocks
What pr ocesses change sedimentary rocks into metamorphic rocks?
heat and pressure, but without melting.
Which two factors affect the temperature that rocks melt at?
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.

When rocks are subjected to extreme pressure and heat without melting within earths crust they may become?
Magma
Can metamorphic rocks be created by melting?
Nope, because they are created when the Earth pressurizes and heats it (but not to the point of melting). Igneous rocks are created when rocks melt.
How do rocks change from metamorphic or sedimentary rocks to igneous rocks?
By melting and then solidifying.

What forms when high temperatures and pressures combine to alter mineralogy or chemical composition of a rock without melting it?
metamorphic rocks
Does melting rocks cause earthquakes?
no
What rocks result from heat and pressure melting into magma?
sedimentary rocks
What steps lead to forming a metamorphic rock?
Existing rocks are buried and subjected to heat and pressure. This causes them to recrystallise without melting.
What temperature do rocks change back to magma?
It depends on the composition of the rock. Felsic (low iron and magnesium, high silica) rocks have a melting temperature closer to 700 degrees C, while mafic (medium silica, high iron and magnesium) and ultramafic rocks have melting temperatures approaching 1200 degrees C. Rocks with intermediate compositions will fall somewhere in between. If you can identify the minerals present in your rock sample, you can predict its melting temperature more accurately. Other factors, including the presence of volatiles such as water vapor or carbon dioxide, or pressure, can influence the melting temperature of a rock.
