Some common intrusive rocks include granite, diorite, and gabbro, while common extrusive rocks include basalt, andesite, and rhyolite. Intrusive rocks form beneath the Earth's surface from slowly cooling magma, while extrusive rocks form from rapidly cooling lava on the Earth's surface.

Is basalt the most common intrusive rock?
No, basalt is actually a type of extrusive igneous rock. The most common intrusive rock is granite.
What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
What are some geographic settings where intrusive and extrusive igneous rocks form?
Intrusive igneous rocks form beneath the Earth's surface in settings like magma chambers and batholiths. Extrusive igneous rocks form on the Earth's surface from volcanic eruptions, such as at mid-ocean ridges, subduction zones, and hot spots.
What is the most common extrusive igneous rock?
Basalt
What 2 types of rock are most common beneath the earths crust?
The two most common types of rock beneath the Earth's crust are basalt and granite. Basalt is an extrusive igneous rock that forms from the cooling of magma on the Earth's surface, while granite is an intrusive igneous rock that forms from the slow cooling of magma beneath the Earth's surface.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
Is basalt the most common intrusive rock?
No, basalt is actually a type of extrusive igneous rock. The most common intrusive rock is granite.

Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
Is basalt a most common intrusive rock?
No. Basalt is the most common extrusive igneous rock.
What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
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.
Is granite rock a extrusive rock?
No, granite is the most common intrusive igneous rock.
Are felsic rocks usually intrusive or extrusive?
Felsic rocks are usually intrusive, meaning they form below the Earth's surface from magma that cools and solidifies slowly. This slow cooling allows minerals such as quartz and feldspar to crystallize and form coarse-grained textures commonly seen in intrusive rocks like granite.
Where are most common extrusive rocks generated from?
mostly in divergent boundary is basalt.
What are some geographic settings where intrusive and extrusive igneous rocks form?
Intrusive igneous rocks form beneath the Earth's surface in settings like magma chambers and batholiths. Extrusive igneous rocks form on the Earth's surface from volcanic eruptions, such as at mid-ocean ridges, subduction zones, and hot spots.
Is micro granite intrusive or extrusive?
Granite is an intrusive type of igneous rock Also since it is intrusive it cools very slowly and forms large crystals and coarse (large) grained igneous rock.
What rocks are formed belows Earth's surface?
Most sedimentary rocks, most metamorphic rocks, and intrusive igneous rocks.
