Basalt is considered igneous because it forms when mafic lava cools at Earth's surface.
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
Basalt is an igneous rock . . . it is pretty much hardened lava.
Yes
because it is a volcanic rock
None. Basalt is formed by the rapid cooling of mafic (silica-poor) magma. It is not formed from sedimentary rock.
Yes. Basalt is an extrusive mafic igneous rock.
Basalt is an extrusive igneous rock.
The volcanic rock can be classified as basalt. Basalt is a fine-grained igneous rock that forms from the solidification of lava flows. The smooth texture and small holes, known as vesicles, are characteristic features of basalt.
Both granite ans basalt are types of 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.
If you're not looking for anything specific, any extrusive igneous rock will have smaller crystals, if any at all. This is because they cool quickly on the surface, leaving little time for crystals to form/grow.

no because it is an igneous rock
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
Basalt and igneous rocks were formed by what we would call magma/lava
Basalt is the most common extrusive igneous rock.
