Can metamorphic rock change into metamorphic rock?
Many ways, really. For example, a continental plate may be submerging underneath another continental plate (a boundary interaction often associated with volcanoes), and in the process, that continental plate that is being submerged, often the ocean floor, changes into metamorphic rock, and if subjected to enough pressure and heat, may become igneous. Or, if two continental plates collide where one plate used to be ocean floor, such as with the Himalayan Mountains, the two plates would jam together. In between these plates, there may be enough heat and pressure to change the sedimentary rock into metamorphic rock.
Is lava a metamorphic rock?
no lava is a liquid that when cooled forms extrusive igneous rock Metamorphic rock is something that has been "metamorphosed" usually by being shoved down into the high temperatures and pressures inside the earth by tectonic plate movement. Sandstone (soft) can become granite (hard) in this way.
What type of rocks formed at divergent plate boundaries?
Mainly metamorphic, due the intense pressure. Some rocks will bend rather than break causing visible folds. Convergent plate boundaries can also produce igneous rocks from volcanic activity due to the subduction of the lighter crustal plate into the mantel which creates a tremendous amount of heat and pressure. Solidified magma may turn into granite. Magma which is blown out from a volcano may take the form of pumice, lava, obsidian, among others.
How does metamorphic rock get to the surface?
Plate Tectonics
What are the two processes that result in a metamorphic rock?
For metamorphic rock to change into igneous rock, it must first melt. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock. Metamorphic rock can become molten by exposure to heat and pressure from depth of burial and compression through tectonic plate subduction, or from close proximity to a magmatic heat source.The metamorphic rock could also become exposed to weathering, erosion, and subsequent deposition, compaction and cementation which would lead to the formation of sedimentary rock. Once again, the sedimentary rock could become molten by exposure to heat and pressure from depth of burial through tectonic plate subduction, or from close proximity to a magmatic heat source. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock.Igneous or sedimentary rock
Does the sun driver the processes that form igneous and metamorphic rocks?
No. Heat from the interior of the Earth trying to reach the surface drives lithospheric plate movements which are mostly responsible for the formation of igneous and metamorphic rocks.

In between these plates, there may be enough heat and pressure to change the sedimentary rock into metamorphic rock.
What processes change igneous rock into metamorphic rock?
Directional pressure and high temperatures are two factors that could cause an igneous rock to metamorphose. Processes that lead to these factors could be tectonic plate movements, depth of burial, or proximity to an intrusive body.
How can sedimentary rock change into metamorphic rock?

For example, a continental plate may be submerging underneath another continental plate (a boundary interaction often associated with volcanoes), and in the process, that continental plate that is being submerged, often the ocean floor, changes into metamorphic rock, and if subjected to enough pressure and heat, may become igneous.

When plate movements cause the crust to bend downward what is formed?
Metamorphic rock i think?
Is a sapphire a igneous metamorphic or sedimentary?
The presence of intrusive magma in an area (known as contact metamorphism), or of tectonic plate interactions on a larger scale (known as regional metamorphism) puts the igneous and sedimentary rocks and minerals under heat or pressure which may cause changes in their chemistry and crystal structure. The result is the creation of metamorphic rocks. Gemstones associated with metamorphic rock include the beryls, jade, lapis lazuli, turquoise, spinel, ruby, sapphire and zircon.
What type of rocks formed at divergent plate boundaries?
Mainly metamorphic, due the intense pressure. Some rocks will bend rather than break causing visible folds. Convergent plate boundaries can also produce igneous rocks from volcanic activity due to the subduction of the lighter crustal plate into the mantel which creates a tremendous amount of heat and pressure. Solidified magma may turn into granite. Magma which is blown out from a volcano may take the form of pumice, lava, obsidian, among others.
Where can you locate sedimentary metamorphic and igneous rocks in a plate boundary?
At a convergent plate boundary, where you get partial melting of the subducting slab. This partial melt rises and pools, forming a magma chamber. When a magma chamber crystallises, the interior will be igneous (probably felsic/ acidic in composition), around the igneous intrusion you will get contact metamorphosed sediments creating a metamorphic aureole, and at the accretion zone you get the accretionary wedge, which is basically sediment which has been scraped off the subduction oceanic slab.
How are metamorphic sedimentary and igneous rocks continues?
Igneous rocks are formed from the cooling of magma that rises up from the mantle. Sedimentary rocks are formed from the compaction of small grains of weathered igneaous or metamorphic rock. Metamorphic rocks are formed from the action of heat and/or pressure on igneous or sedimentary rocks. Finally, subduction process at certain plate boundaries return all three rock types to the mantle. So there exists a contiuous cycle between the three types of rock; starting with igneous rocks, perhaps becoming sedimentary rock or metamorphic rock or both, then returning to the mantle.
Why is sedimentary rock more common on earths surface than metamorphic or igneous rock?
== == == Erosion and weathering of igneous, metamorphic, and sedimentary rocks eventually leads to formation of more sedimentary rock. Additionally, huge areas of continents have been covered by inland seas at one time or another in geologic time creating vast amounts of sedimentary rock. Plate tectonics also plays a role in the thrusting upward of areas that once were ocean floor.
What is magmatism?
The formation of igneous rock from magma For example the formation of volcanoes or island arcs at convergent plate boundaries. Or mid-ocean ridges and therefore ocean-floor spreading at divergent plate boundaries.
