Gabbro is an example of which type of rock?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Igneous rock.
Gabbro is an example of an intrusive igneous rock. It forms when magma cools slowly beneath the Earth’s surface, allowing large crystals to develop. Gabbro is coarse-grained and composed mainly of minerals like pyroxene, plagioclase feldspar, and sometimes olivine. Its color is usually dark green to black due to its high content of mafic minerals. Gabbro is commonly found in the oceanic crust and is used as a building material, decorative stone, and in road construction because of its hardness and durability.
