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.
Does metamorphism usually involve melting?
No, metamorphism usually does not involve melting. Instead, it involves changes in temperature and pressure that alter the mineral composition and texture of rocks without causing them to melt completely.
What type of metamorphism would result in a schist?
Regional metamorphism would result in the formation of schist. This type of metamorphism occurs under high pressure and temperature conditions over large areas, such as during the collision of tectonic plates. Schist forms from the recrystallization of existing rocks like shale or slate, resulting in distinct foliation and often containing minerals like mica or quartz.
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
Under great heat and pressure limestone can form marble What correctly describes this change in rock type?
Metamorphism. The heat and pressure can be from depth of burial or from regional metamorphic processes, such as those that would be due to plate collisions Because limestones (the parent rock of marble) are largely made up of one mineral, calcite, and calcite exhibits stability over a wide range of temperatures and pressures, metamorphism of limestone only causes the original calcite crystals to grow larger. Therefore, the limestone can change to marble either by contact metamorphic processes (from proximity to, or contact with, a molten intrusion into a limestone parent rock) or regional processes due to tectonic plate movements, or from depth of burial.

Why doesn't metamorphism occur when rocks come in contact with magma?
Metamorphism does occur when rocks come in contact with magma but it is very localised. It is contact metamorphism and a close look with a hand lens will normally show a change to the rock, sometimes only millimetres wide.
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.
Why does metamorphic rock rarely forms at earth's surface?
All metamorphism (in Geological terms) requires heat, whether it is Thermal or Regional:Thermal is heat only. It happens at the surface mainly. This happens upon contact with an igneous intrusion, and in a burnt margin in an extrusion/unconformity like a lava flow.Regional is both heat and pressure. It happens deep beneath the surface only.
Metamorphic rock that consist of only mineral that forms large interlocking crystals often have what type of texture?
Metamorphic rocks that consist of only one mineral and have large interlocking crystals often have a coarse-grained texture. This means that the individual mineral grains are easily visible to the naked eye. Examples of such rocks include quartzite (formed from quartz) and marble (formed from calcite).
Does metamorphism usually involve melting?
No, metamorphism usually does not involve melting. Instead, it involves changes in temperature and pressure that alter the mineral composition and texture of rocks without causing them to melt completely.

What is the past tense of forms be?
was, were (the only verb with 2 forms).
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
Where do you print a girl scout cookie order form?
Since the 2009 Girl Scout Cookie Sale is now over, the only way to possibly find a cookie order form would be to contact someone who collects Girl Scout items or contact a Girl Scout council and ask if they might have saved any forms.
