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 is another word for change in metamorphic rocks?
Metamorphism.
What type of rocks can undergo metamorphism?
All types of rocks, including igneous, sedimentary, and metamorphic rocks, can undergo metamorphism under the right conditions. Metamorphism occurs when rocks are subjected to high temperatures, pressures, or chemical reactions, causing them to recrystallize and change in mineral composition and texture.
What processes found at hot spots will help metamorphic rock form?
When a rock is subjected to pressure greater than 1500 bars and temperatures higher than 150 - 200°C it undergoes a process known as metamorphism which causes a profound chemical and/or physical change to the rock.
What two processes can change a rock into a metamorphic rock?
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.
Can a metamorphic rock become further metamorphic?
Yes, additional pressure and heat will lead to further metamorphism. The reference used to describe this is called the 'degree of metamorphism'. For instance, the sedimentary rock shale can become the low grade metamorphic rock slate. In the next degree of metamorphism, slate can become phyllite. Phyllite can then become schist, and finally gneiss. Migmatite is the highest grade metamorphic rock, but has been partially melted.
What is another word for change in metamorphic rocks?
Metamorphism.
What signals the end of metamorphism?
Metamorphism typically ends when the external conditions (temperature, pressure, and chemical environment) that drive the process change. This change can lead to either the formation of new minerals or the cessation of metamorphic reactions, indicating the end of metamorphism. Metamorphism can also end when the rocks are uplifted to shallower depths in the Earth's crust, where conditions no longer support metamorphic processes.
What is Another word for change in metamorphic?
Metamorphism, transformation...
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
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 heat change rooks to metamorphic rocks?
Heat causes the minerals in rocks to recrystallize and rearrange, resulting in new mineral structures and textures. This process, known as metamorphism, can change the physical and chemical properties of the rock, transforming it into a metamorphic rock like marble or schist.
Can a metamorphic rock change again after already being changed once?
Yes. There are degrees of rock metamorphism, where a metamorphic rock can be altered into another metamorphic rock by increased pressure and heat.
How would a sedimentary rock change to a metamorphic rock?
Through metamorphism, as a result of increase in pressure and/or temperature.
What rock is formed when limestone goes under metamorphic change?
When limestone undergoes metamorphic change, it can be transformed into marble. Marble is a metamorphic rock that is composed of recrystallized calcite or dolomite minerals. It is known for its beautiful veining and is commonly used in architecture and sculpture.
What type of rocks can undergo metamorphism?
All types of rocks, including igneous, sedimentary, and metamorphic rocks, can undergo metamorphism under the right conditions. Metamorphism occurs when rocks are subjected to high temperatures, pressures, or chemical reactions, causing them to recrystallize and change in mineral composition and texture.
How could an igneous rock change to a metamorphic rock?
Under influence of pressure and temperature, a rock can change, the process is called deformation or metamorphism, the result is a metamorphic rock. This can happen to igneous rocks as well.
What processes found at hot spots will help metamorphic rock form?
When a rock is subjected to pressure greater than 1500 bars and temperatures higher than 150 - 200°C it undergoes a process known as metamorphism which causes a profound chemical and/or physical change to the rock.
