Question

Classify igneous rocks based on their origin and give example of each ?​

Answer 1

Answer:

Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic. The diagram of Bowen's reaction series shows that differences in chemical composition correspond to differences in the types of minerals within an igneous rock.

Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface.
