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?
During metamorphism, the minerals present in the rock can recrystallize, change in size, or reorganize their structure due to the influence of the hot fluids. The chemical composition of the rock may also change as elements are exchanged between the rock and the fluids. Overall, these processes can lead to the formation of new minerals and textures in the rock.
Metamorphism involves what two conditions act on the existing rock to change it?
Metamorphism involves the combination of high temperature and pressure acting on the existing rock to change its mineral composition and texture. These conditions can alter the rock without completely melting it, leading to the formation of metamorphic rocks.
What is an agent of metamorphism related to temperature?
An agent of metamorphism related to temperature is heat. Heat causes minerals in rocks to recrystallize or change mineral composition, leading to metamorphic changes in the rock. Temperature influences the degree of metamorphism and the types of minerals that form during the process.
Which agent of metamorphism can cause the overall composition of rock to change?
Hydrothermal fluids are a common agent of metamorphism that can cause the overall composition of a rock to change. These fluids can introduce new minerals into the rock through chemical reactions, altering its composition and structure.
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.
Which is not a change that may occure during metamorphism?
The rock material melts
What are hot fluids migrating into and out of a rock during metamorphism can change the rock's what?
Hot fluids migrating into and out of a rock during metamorphism can change the rock's mineral composition, texture, and overall structure. This process, known as metasomatism, allows for the introduction of new minerals and the alteration of existing ones, leading to significant changes in the rock's properties. Additionally, these fluids can enhance chemical reactions and facilitate the recrystallization of minerals, further transforming the rock.

When a rock changes due to the surrounding pressure on all sides what has occured?
The rock has undergone metamorphism. Metamorphism is the process in which the mineral composition and texture of a rock change in response to heat, pressure, or chemical reactions. This can result in the formation of new minerals and changes in the rock's appearance and physical properties.
How does hot fluid change the mineral composition of a rock during metamorphism?
Hot fluid dissolves materials and adds other materials :)
What changes in a rock during metamorphism?
The high temperatures required for metamorphism ultimately are derived from Earth's eternal heat, either through deep burial or from nearby igneous intrusions. The high pressures required for metamorphism can be generated in two ways: from vertical pressure caused by the weight of overlying rock, or from the compressive forces generated as rocks are deformed during mountain building.

What state is metamorphic rock formed in?
Metamorphism is the name of the process (of heat and pressure) that causes the chemical; and therefore mineralogical; properties of a rock to change. Marble (changed from limestone) may represent the lowest grade of metamorphism, whilst the schists are a more common higher grade of that same process. At the extreme, the rocks will melt, but that is considered beyond the definition of metamorphism, for it will change the actual chemical nature of the rock. So - it is the application of heat and pressure; perhaps accompanied by shear; that are the metamorphic change agents. Usually caused by deep burial.
What changes when hot fluids migrating into and out of a rock during metamorphism?
grade
Why can the chemical composition of rock be changed during metamorphism?
It is an open system; atoms can move into and out of the rock.
