A metaporphic rock is formed when a rock is put under extreame heat and preasure for many (often thousands or millions) of years. This changes it into a new type of rock. This new rock is called a Metamorphic rock.

What causes contact metamorphism?
contact metamorphism occurs when hot magma bakes rocks
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by regional metamorphism?
Contact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.
If metamorphism causes a rock to melt would the rock that results still be consider a metamorphic rock?
=== === Metamorphism does not cause a rock to melt. If a rock melts, then solidifies, it is by definition an igneous rock. There are rocks called granulites which represent the highest grade of metamorphism, and some may have experienced a partialmelting.
What causes regional metamorphism?
Regional metamorphism occurs due to the change in pressure and temperature over a large region of the crust. It is the result of high pressure and elevated temperatures that are associated with deep burial in an organic belt.
What are the Three types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
What causes contact metamorphism?
contact metamorphism occurs when hot magma bakes rocks
What is the process other than heat that causes metamorphism?
pressure.
What are two processes to cause metamorphism?
what are the physical conditions that causes metamorphism?
What is the process called other than heat that causes metamorphism?
pressure.
What are two sources of heat and pressure that causes metamorphism?
maybe heat can make have the pressure
What occurs when heat from nearby magma causes changes in the surrounding rocks?
intrusive metamorphism
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by regional metamorphism?
Contact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.
What are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
What limits the maximum temperatures possible in metamorphism?
The maximum temperature that creates metamorphism is the temperature just below that which causes a rock to melt. Once a rock melts, then solidifies, it is considered an igneous rock.
If metamorphism occurs due to heat generated by magma it is called metamorphism?
It is called contact metamorphism.
