Where regional (prograde) occur?

Retrograde metamorphism involves the reconstitution of a rock via revolatisation under decreasing temperatures (and usually pressures),


What are the 4 ways by which metamorphism may occur?

Metamorphism can occur through contact metamorphism, where rocks are altered by heat from nearby magma; regional metamorphism, where rocks are subjected to high pressure and temperature over a large area; burial metamorphism, where rocks are subjected to increased pressure from being buried deep underground; and dynamic metamorphism, where rocks are deformed under high pressure but low temperature conditions along faults or shear zones.


What type of metamorphism contact or regional would result in a schist explain your choice?

Regional metamorphism would result in the formation of schist. Schist is a metamorphic rock that forms under high pressure and temperature conditions over a large area, which is characteristic of regional metamorphism. This process causes the original minerals in the rock to recrystallize into new minerals, giving schist its foliated texture.


Regional metamorphism of limestone produce?

Regional metamorphism of limestone can produce marble, a metamorphic rock with crystalline structure and interlocking grains. This process involves the recrystallization of the limestone minerals under high temperature and pressure, resulting in the formation of a more compact and durable rock with distinct colors and patterns.


What is the difference between thermal metamorphism and regional metamorphism?

Thermal metamorphism is a type of metamorphism that occurs due to the heat from a nearby igneous intrusion, leading to changes in the mineralogy and texture of rocks. Regional metamorphism, on the other hand, is caused by high pressure and temperature over a large area, typically associated with tectonic plate collision or subduction. The main difference lies in the scale and mechanism of metamorphic changes, with thermal metamorphism being more localized and regional metamorphism affecting larger regions.


Is gneiss contact or regional metamorphism?

whatever the f*** it is, nobody gives a darn


What rock is only formed by regional metamorphism?

Schist is a type of rock that is primarily formed through regional metamorphism. This process occurs over large areas under high pressure and temperature, typically associated with tectonic forces. Schist is characterized by its well-developed foliation and often contains visible mineral grains, such as mica, which give it a shiny appearance. Other metamorphic rocks can form through different processes, but schist is distinctly linked to regional metamorphism.


Which sedimentary rock is most likely to be changed to slate during regional metamorphism?

Shale is the most likely sedimentary rock to be changed into slate during regional metamorphism. Shale is a fine-grained sedimentary rock composed of clay minerals, which are easily recrystallized under heat and pressure to form the dense, foliated texture characteristic of slate.


Are volcanoes made by plates sliding away from each other?

Many are but many others are not. Most volcanoes on land occur where two plates press into each other and one slide slides under the other. Some volcanoes occur at hot spots, which are not related to plate boundaries.


What type of rock can only form deeply underground?

Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.


Where does the eruption of lava occur?

right beneath the thin crust of the lava that was dried and under the volcanoes in alot of cavities


Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by reg?

Because in contact the rock actually comes in contact with magma, this joins with the rock, so when it cools and become igneous rock, it's denser. In regular, or regional, the rock is formed from intense heat and pressure, but does not actually come in contact with magma.
