Is basalt the most common intrusive rock?
Yes, Basalt is the most common extrusive rock
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?
Yes, Basalt is the most common extrusive rock

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.
Which magma would cool most rapidly extrusive or intrusive?
Extrusive magma cools most rapidly compared to intrusive magma. This is because extrusive magma, or lava, is exposed to the cooler temperatures of the Earth's atmosphere or water when it erupts and flows on the surface. In contrast, intrusive magma cools slowly underground, where it is insulated by surrounding rock. The rapid cooling of extrusive magma often results in the formation of fine-grained or glassy textures in volcanic rocks.
Where are most common extrusive rocks generated from?
mostly in divergent boundary is basalt.
What is the most common texture for intrusive rocks?
The most common texture for intrusive rocks is coarse-grained, or phaneritic texture. This texture occurs because intrusive rocks, formed from magma that cools slowly beneath the Earth's surface, allow large crystals to grow. Examples of coarse-grained intrusive rocks include granite and diorite. The slow cooling process results in the visible crystalline structure characteristic of these rocks.
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.
