Why do minerals change composition as they undergo metamorphism?

The minerals in the rock have been realigned into parallel bands in response to pressures exerted on the rock from a particular direction. The banding forms perpendicularly to the direction of the force.

∙ 11y agoFoliated rock can form in one of two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foliation also occurs as minerals that have different compositions separate to produce a serious of alternating dark and light bands.

What agent of metamorphism can cause the overall composition of the rock to change?
hydrothermal solutions
Metamorphism occurs at hotspots where magma rises up through Earth.?
Contact
What does undergo physical or chemical changes mean?
if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
What is the most common type of metamorphism?
The most common type of land metamorphism is Regional metamorphism. The most common rocks are slates, schists, and gneisses. This occurs within the folds of mountain belts and cratonic areas.
Which type of metamorphism is most likely to change shale to hornfels?
Contact Metamorphism
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 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.
What is the most important agent(s) of metamorphism?
Metamorphism is the change in the structure or composition of rocks. The most important agents of metamorphism are heat and pressure.

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
What process causes the mineral composition of the rock to change?
The process is called metamorphism, the alteration of chemical composition or structure due to heat and/or pressure.
Minerals in rock near a volcano recrystallize as lava covers the area--the minerals change due to the lava's?
The minerals in the country rock might change due to the effects of the heat in a process known as contact metamorphism.
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
Metamorphism occurs at hotspots where magma rises up through Earth.?
