Answer:
C. basalt
Explanation:
Basalt -
It is a type of mafic extrusive igneous rock which is composed of magnesium and iron lava , is called as a basalt .
Around 90% of the rocks of the Volcanoes are made up of Basalt .
The texture of this Basalt is , finely grained , because , the rocks are found by rapid cooling .
The viscosity of Basalt is low , due to its low content in silica .
The Basalt is only the one extrusive igneous rock with a fine grained-texture, low silica content and dark color.
Basalt is known as the aphanitic extrusive igneous rock, which was formed from the fast cooling of low-viscosity lava rich in magnesium and iron exposed at or very near the surface of a rocky planet or moon. Basalt can be made into fiber, and the basalt fiber is frequently used as a safe substitution for asbestos.
More than 90% of all (volcanic)mountain rock on Earth is basalt. It is a fine grained-texture, low silicon oxide content and dark in color. Basalt has also constituted on the earth of Moon, Mars, Venus, and even on the angular Vesta.
Therefore, option C is correct.
