Subduction is the geological process where one tectonic plate moves under another and sinks into the mantle, leading to significant geological activity. As the subducting plate descends, it generates heat and pressure, causing the release of fluids that can lower the melting point of the overlying mantle. This results in the formation of magma, which can rise to the surface and solidify as igneous rocks, often leading to volcanic activity. Therefore, subduction zones are critical locations for the generation of igneous rocks, particularly in volcanic arcs.
What else can I help you with?
Is it true Andesitic rock is an igneous rock with a composition in between that of basaltic and granitic igneous rock.?
Yes, andesitic rock is indeed an igneous rock that has a composition situated between basaltic and granitic rocks. It typically contains a moderate amount of silica, ranging from about 57% to 63%, which gives it characteristics that are intermediate between the two. Andesitic rocks are commonly found in volcanic arcs and are often associated with subduction zones.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
Is Andesitic rock is an igneous rock with a composition in between that of basaltic and granitic igneous rock.?
Yes, andesitic rock is an igneous rock that has a composition intermediate between basaltic and granitic rocks. It typically contains a mix of minerals such as plagioclase feldspar, amphibole, and sometimes biotite or quartz. Andesitic rocks are commonly associated with volcanic arcs and are often found in subduction zone environments. Their formation occurs from the partial melting of the Earth's mantle and the mixing of different magma types.
How do igneous rocks change into 'sedimentary rocks?
AnswerUsually by subduction of sedimentary rock at plate boundaries, melting, and deposition as solidified crustal igneous rock, either extrusive or intrusive.

How does the subduction of crustal plates influence the rock cycle?
The subduction of crustal plates plays a crucial role in the rock cycle by driving the recycling of Earth's materials. As an oceanic plate descends beneath a continental plate, it melts and contributes to magma formation, leading to igneous rock creation. Additionally, the intense pressure and heat at subduction zones can transform sedimentary and igneous rocks into metamorphic rocks. This process continually reshapes the Earth's crust, facilitating the transition between different rock types.
When molten rocks cools what rocks form?
igneous rocks
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.
What does cycle?
cycle means it cycles between sedimentary,metamorphic and igneous rocks. cycle means it cycles between sedimentary,metamorphic and igneous rocks. -Mrs.Zalenski
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What processes found at convergent boundary will help form the following rocks?
At a convergent boundary, the processes of subduction, where one tectonic plate is forced beneath another, can lead to the formation of metamorphic rocks such as schist and gneiss. Additionally, the intense heat and pressure generated by the collision of two plates can cause the melting of rocks, leading to the formation of igneous rocks like granite.

Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
What is the name for rocks changing between sedimentary metamorphic and igneous rocks?
The rock cycle.
What is the similarity between granite and basalt?
Both are igneous rocks.
