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 else can I help you with?
Match the type of metamorphism to its best definition.?
Contact metamorphism - the process in which a rock changes as a result of heat generated from magma Dynamic metamorphism- the process in which a rock changes due to pressure directed onto it impact metamorphism - the process in which a rock changes because of extreme heat and pressure caused by a meteorite collision with earth regional metamorphism- the process in which buried rocks in a large area are changed by heat pressure and fluids
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
Which type of metamorphism is most likely to occur along the fault line?
Dynamic Metamorphism >.<
Would you be less likely to find fossils in metamorphic rock than a sedimentary rock?
Metamorphic rock can contain fossils, but since these rocks form under intense heat and pressure where stone flows something like taffy, the fossils will be highly degraded and distorted.Sedimentary rock forms when layers of silt are Why_are_you_less_likely_to_find_fossils_in_metamorphic_rock_than_sedimentary_rockon the bottom of a body of water. When conditions are right, layers form quickly and are not disturbed and little oxygen is present, dead creatures that fall on that bottom can become entombed in preserved at the layers are increasingly compressed, eventually cementing into rock.
How do systems change over time?
depends on the tectonic events driving them, they can splay, reactivate, become locked..... any number of things, however the rupture plain will remain between the rock unless re crystalized by melting or 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 changes when hot fluids migrating into and out of a rock during metamorphism?
grade
What changes the form of existing rock?
METAMORPHISM.
What are changes in metamorphism?
The rock material melts
What is a dynamic to metamorphism?
A process that changes rock due to directed pressure on a rock
What is a dynamic metamorphism?
A process that changes rock due to directed pressure on a rock
How do chemically active fluids affect metamorphism?
Chemically active fluids can enhance metamorphism by facilitating mineral reactions and changing the mineral assemblage in a rock. These fluids can introduce new elements into the rock, catalyze reactions, and promote recrystallization, leading to the development of new minerals or changes in texture and structure of the rock during metamorphism.
What are the two changes of a rock of metamorphism?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
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 two properties of rock change during metamorphism?
During metamorphism, the texture and mineralogy of a rock can change. Texture refers to the size, shape, and arrangement of grains within the rock, while mineralogy refers to the types of minerals present in 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.
Do crystals grow larger during metamorphism?
During metamorphism, crystals can grow larger through a process called recrystallization, where existing minerals rearrange their atoms to form larger crystals. This can happen due to changes in temperature, pressure, or the presence of fluids in the rock. So, yes, crystals can grow larger during metamorphism.
