It is altered physically by pressure and heat and can align the existing minerals into layers or bands called foliations; new minerals may be formed from the minerals that existed before the metamorphism; aqueous solutions between rock particles are squeezed out; and existing minerals may recrystallize.

What is the original rock called before metamorphism takes place?
It is called the 'protolith' or 'parent rock'.
When changes in pressure temperature or chimical make-up alter a rock what takes place?
metamorphic rock metamorphic rock, or metamorphism
What takes place when changes in presure or temperature or chemicle makeup alter a rock?
Metamorphism. Also, learn how to spell properly.
What has to happen for metamorphism?
the parent rock must be in solid form
What is a nonfoliated rock formed by contact metamorphism of a shale or mudstone?
Contact metamorphism takes place locally near igneous intrusions. It is caused by low to moderate pressure, intense heat, and reactions to magma that is being metamorphosed. When contact metamorphism takes place with mudstone or shale (sedimentary rocks) slate is formed. The mudstone or shale is the parent rock or protolith.
What happen for metamorphism to occur?
the parent rock must be in solid form
The kind of metamorphism that occurs when rock come into contact with a heat source such as magma and the rock surrounding the heat source get cooked?
It is called contact metamorphism. It takes place when the magma at high temperature tries to break out from the magma chamber, it then comes into contact with the country rock at high pressure and temperature.
What will happen if a sedimentary rock is exposed to heat and pressure?
It would undergo metamorphism, if the heat and pressure are sufficient.
Bural metamorphism occurs when hot magma or lava comes in contact with rock?
No. This is contatc metamorphism. Burial metamorphism occurs when rock is altered due to the weight of overlying rock.
Takes place when magma intrudes rock?
It is called a dyke or dike, and could also be referred to as a discordant igneous intrusion.
How do the effects of contact metamorphism compare with those of regional metamorphism?
contact and regional metamorphic are similar because both of them happen cause of hot heat and pressure which make the rock metamorphic
Which type of metamorphism affects the greatest volumes of rock?
Regional metamorphism
