What else can I help you with?
Was slate once shale?
Yes, slate was once shale. Shale is a sedimentary rock formed from the compaction of mud and clay, while slate is a metamorphic rock that forms from the metamorphism of shale. The process of metamorphism involves heat and pressure, which transforms the shale into slate by aligning the minerals and creating a foliation (layering) within the rock.
What rocks changes its form from once igneous or sedimentary?
metamorphic
What is mica called once its formed intoa metamorphic form?
Mica.
What can happen to a rock once its form?
it can turn into molten rock it can be heated and pressured and turn into metamorphic it can weather and turn to sediments
What was Once?
The metamorphic rock marble was once the sedimentary rock limestone.
What is a metamorphic rock that was once granite?
Gneiss
What was marble once?
The metamorphic rock marble was once the sedimentary rock limestone.
Can metamorphic rocks be sedimentary or igneous rocks?
there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through. -Cutegirl99
What rock was once shale?
Shale is a sedimentary rock that can transform into other types of rock through the process of metamorphism. Under heat and pressure, shale can turn into slate, while further metamorphism can result in the formation of phyllite, schist, and gneiss.
What is the definoiton of metamorphic rock?
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks.
Can a metamorphic rock change again after already being changed once?
Yes. There are degrees of rock metamorphism, where a metamorphic rock can be altered into another metamorphic rock by increased pressure and heat.
The mining of oil shale requires?
The mining of oil shale requires conversion of the solid hydrocarbons in the rock to liquid form, so that they can pumped or processed.This is done by heating the rock to a high temperature, and separating and collecting of the resultant liquid. This heating process is called retorting.
