∙ 7y agoThey are commonplaces because they have deep cracks where magma can come from. And we all know that igneous rock is molten lava that has been cooled, so this answer will make sense.

Why are rift zones a common spot for igneous rock to form?
The thinned crust in rift zones results in the formation of magma (molten rock) in the upper mantle, which then rises through the crust. As a result, rift zones often have active volcanoes, which form new igneous rocks.
Where would metaphoric rocks form?
Usually deep underground from heat and pressure, at regional metamorphic zones in areas of continental collisions, and in contact zones where parent rock is metamorphosed from proximity to an intrusive igneous body.
What are vegetation zones?
vegetation zones are zones that are made up of common vegetation characteristics
Huge igneous rock structures have zones of weakness called?
Usually referred to as a "fault".
Where are metamorphic rocks made?
Metamorphic rocks are either created at great depth, or at contact zones with magmatic intrusions.
Why are rift zones common places for igneousrock to form?
so magma can cool below earth surface to from igneous rocks.
Why are rift zones common places for igneous rocks?
The thin crust of a rift zone causes melting in the upper mantle, resulting in volcanic activity.
Why are igneous rock found in collision zones?
There are many explanation to your question. The most abundant type of rocks in collision zones are metamorphic rocks. But if there is a igneous it can as a result of convergence boundaries. In subduction zones where rising magma are penetrate through weaker rocks to form form lava and when solidified forms igneous rocks. You can also find them in accretion zones. Where 2 continental plates are accreted due to plate movement. They are not newly formed igneous. they have been there for years before accretion.

Are all lowlands are made primarily of sedimentary rocks?
Rift zones are lowlands composed of igneous rock.
Where can ignoeus rock be found?
Igneous rocks form only in certain places. Fractionation occurs mostly where tectonic plates are either moving apart at mid ocean ridges or pushing together at subduction zones.
What processes found at convergent boundary will help form the following rocks?
The processes found at convergent boundary that help in the formation of rocks are subduction zones. Igneous rocks form around convergent boundaries.
Where would metaphoric rocks form?
Usually deep underground from heat and pressure, at regional metamorphic zones in areas of continental collisions, and in contact zones where parent rock is metamorphosed from proximity to an intrusive igneous body.
What has the author Nelly Cabanes written?
Nelly Cabanes has written: 'Etude de zones de cisaillement mantellique' -- subject(s): Crust, Earth, Igneous Rocks, Inclusions, Mantle, Peridotite, Rock deformation
What are three methods of intrusive igneous rock formation?
There are three methods of intrusive igneous rock formation. Igneous rock can form at mid ocean ridges, subduction zones, and at the continental crust if it is pushed together.
What are vegetation zones?
vegetation zones are zones that are made up of common vegetation characteristics
