Solution(By Examveda Team)

Basalt rock is volcanic (extrusive) in nature.
Extrusive igneous rock is also known as volcanic rock and is formed by the cooling of molten magma on the earth's surface.
Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity and forms thin flows that can travel long distances.
