What is a dynamic to metamorphism?
A process that changes rock due to directed pressure on a rock
What is the difference between regional and contact metamorphism?
Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.
What kind of metamorphism occurs when intrusive magma forms a sill between two sedimentary rock strata?
contact metamorphism
How does a sedimentary rock turn into a metamorphic rock then into an igneous rock?
First, through metamorphism, then by melting and magmatism.
Why is sedimentary rock converted into metamorphic rock?
Sedimentary rock is formed generally at low temperature and pressure conditions.Therefore a change in this conditions to higher levels triggers mineralogical change.The driving forces for metamorphism are changes in temperature, pressure, and composition of the environment or strong deformation.These changes cause recrystallization in the solid state as the rock changes toward equilibrium with the new environment.Hence, formation of metamorphic rocks.
Metamorphism involves what two conditions act on the existing rock to change it?
Metamorphism involves temperature and high pressure and chemical changes. The high pressure, chemical changes and temperature are the metamorphism that act on a rock that makes it change.
What changes the form of existing rock?
METAMORPHISM.
What are changes in metamorphism?
The rock material melts
When a rock changes due to surrounding pressure on all sides?
Burial metamorphism
How can a rock become another rock?
By undergoing changes, such as weathering and metamorphism.
What is a dynamic metamorphism?
A process that changes rock due to directed pressure on a rock
What is a dynamic to metamorphism?
A process that changes rock due to directed pressure on a rock
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
When a rock changes because of surrounding pressure?
Burial Metamorphism :) <3
Which term indicates changes in rock due to the injection of magma?
Igneous metamorphism
What two geological processes are involved in changing sedimentary rock to 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.
