What is the planar alignment of minerals due to differential stress during metamorphism?
Foliation
What does the radiometric date of metamorphic rock most likely represent?
heated during metamorphism
The makeup of rocks is changed during?
The make up is changed when the mineral composition undergo metamorphism.
What is recrystallization process?
A process by which bonds between atoms in minerals break and reform in new ways during metamorphism.
Where does the water involved in melting at subduction zones come from?
Water contained within minerals in the subducting plate is released during metamorphism.
What do rock depend on during metamorphism?
Rocks just "are", they are not alive and therefore they do not depend on anything.
What two properties of rock change during metamorphism?
The properties of temperature and pressure both change when rocks undergo metamorphism. Re-crystallization and chemical reactions also occur during metamorphism.
The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
What are the three main types of metamorphism Compare and contrast the factors that cause each type?
The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers. Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance. Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.
What process can occur during metamorphism?
everything
Do minerals partly melt during metamorphism?
no
Why does the color of sedimentary rock change during metamorphism?
The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.
What is responsible for the increase in temperature during contact metamorphism?
mr.mosser
What physical change in metamorphic rock signals the end of metamorphism?
from what i know there is no physical change that signals the end of metamorphism but there is a physical change during the process of metamorphism. during metamorphism the shape of the rock changes due to force of stress this is a physical change. (a physical change is when the shape or composition ofa substance e.g. rock has changed). by the way i am only 12
When hot fluids migrate into and out of a rock during metamorphism what will change?
grade
What is the process in which a mineral changes composition during metamorphism's called?
recrystallization
Which is not a change that may occure during metamorphism?
The rock material melts
