At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
Bural metamorphism occurs when hot magma or lava comes in contact with rock?
No. This is contatc metamorphism. Burial metamorphism occurs when rock is altered due to the weight of overlying rock.
The kind of metamorphism that occurs when rock come into contact with a heat source such as magma and the rock surrounding the heat source get cooked?
It is called contact metamorphism. It takes place when the magma at high temperature tries to break out from the magma chamber, it then comes into contact with the country rock at high pressure and temperature.
What kind of rock is formed by metamorphism of limestone or dolomite?
marble
Is a rock called shale formed from the skeletons of the ancient coral animals?
No . Shale is formed my the metamorphism of the rock - Slate

What is a nonfoliated rock formed by contact metamorphism of a shale or mudstone?
Contact metamorphism takes place locally near igneous intrusions. It is caused by low to moderate pressure, intense heat, and reactions to magma that is being metamorphosed. When contact metamorphism takes place with mudstone or shale (sedimentary rocks) slate is formed. The mudstone or shale is the parent rock or protolith.
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by regional metamorphism?
Contact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.
What rocks are formed by magma?
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
Why are metamorphic rocksformed by contact metamorphism usually not as dense as those formed by regional metamorphism?
Because contact metamorphism usually occurs because of an increase in temperature. In contrary, regional metamorphism is usually the result of compression. Compression makes a rock more dense.
What is the difference between contact and metamorphism?
Contact metamorphism is metamorphism that happens when preexisting rock comes in contact with a molten rock or magma and it melts locally.Regional metamorphism is metamorphism happens when two plates collide the plate that subducts can melt by the heated area.
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.
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.
Is metasedimentary rock intrusive?
No, its a metamorphic rock formed by metamorphism of sedimentary rock.
What process forms hornfels?
Hornfels is formed when mudstone or shale come in contact with a hot igneous body and metamorphic rock. This process is called contact metamorphism.
Bural metamorphism occurs when hot magma or lava comes in contact with rock?
No. This is contatc metamorphism. Burial metamorphism occurs when rock is altered due to the weight of overlying rock.
