What else can I help you with?
Are most plate boundaries on continents or in ocean basins?
Most plate boundaries are located in ocean basins rather than on continents. This is because oceanic plates are denser than continental plates, leading to subduction zones and mid-ocean ridges where most of the plate boundaries are found in the oceans.
What is the most extrusive igneous rock?
Basalt is the most common extrusive igneous rock.
Which is not a common extrusive igneous rock?
There are so many rocks that can be classified as not a common extrusive igneous rock. The most common extrusive igneous rock is basalt. Extrusive rocks are formed as a result of lava solidifying.
What type igneous rock makes up most of the ocean floor?
Basalt

Are igneous rocks the most common rocks?
Igneous rock is by far the most common rock of the crust.
What is the most common igneous rock on the ocean floor?
Basalt is the igneous rock which makes up most of the ocean floors. It is smooth and velvety-black in appearance and very hard. New seafloor is constantly produced at the mid-ocean rifts, where areas between spreading tectonic plates are infilled with rapidly cooling lava.
What is the most extrusive igneous rock?
Basalt is the most common extrusive igneous rock.
Is granite in the igneous family?
Yes. Granite is one of the most common igneous rocks.
The most common continental igneous rock?
Granite
What is the most common mineral in igneous rocks?
calcite
What is the most common type of intrusive?
igneous rock
Is basalt a most common intrusive rock?
No. Basalt is the most common extrusive igneous rock.
What is the most common extrusive igneous rock?
Basalt
What is the most common rock found in Iceland?
Iceland, an exposed area along the mid-ocean ridge would consist largely of the extrusive igneous rock basalt.
