What are the processes involve in the formation of rocks?
Heating, pressurization, deformation, recrystallization, and metamorphism.
How does (prograde) occur?
In general, the changes in mineral assemblage and mineral composition that occur during burial and heating are referred to as prograde metamorphism.
What are some types metamorphic rock?
These rocks get their name from the Greek words 'meta' and 'morph', meaning 'change of form'. Metamorphic rocks are produced by the alteration of pre-formed rocks by pressure, temperature and migrating fluids, often in environments deep in the Earth's crust. Because of the severe conditions which rocks undergo during metamorphism, the original minerals may become unstable and change to maintain equilibrium with the new environment. This can involve changes in mineralogy (recrystallization of existing minerals or formation of new ones) and usually changes in texture from the original rock. Three main types of metamorphism are recognized. Regional metamorphism results from mountain-building events with large scale folding and burial of pre-formed rocks. Contact metamorphism is produced by direct heating of rocks around an igneous intrusion, baking the surrounding country rocks. Dynamic metamorphism occurs where large scale faulting breaks and deforms rocks next to the fault.
Why are metamorphic rocks formed by contact metamorphism usually not dense or resistant?
Metamorphic rocks formed by contact metamorphism are usually not dense or resistant because they are formed at relatively low pressures and temperatures compared to regional metamorphism. The short duration of the heating process in contact metamorphism does not allow for the recrystallization and reorganization of mineral structures that contribute to denser and more resistant rocks. Additionally, the presence of fluids and gases in contact metamorphism can facilitate alteration and weakening of the original rock material.
How does contact (prograde) occur?
In general, the changes in mineral assemblage and mineral composition that occur during burial and heating are referred to as prograde metamorphism.
How does a mineral get its shape?
minerals get its crystal shape by the heating and pressure from rock
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
What happens to heated water after the heating?
Evaporates
What happens when heating a magnet?
it will loose its magnesium
What happens when you heat copper over a Bunsen flame?
Heating copper over a Bunsen flame will cause it to change color from its original reddish-brown to a dark brown/black color due to the formation of copper oxide on its surface. Continued heating can cause the copper to eventually melt and form a molten liquid.
What happens if you use kerosene instead of heating oil?
Kerosine and heating oil are the same thing
How does a mineral gets its crystal shape?
minerals get its crystal shape by the heating and pressure from rock
