What are the main characteristics of Igneous rocks? Classify Igneous rocks on the basis of place of origin and chemical composition.

Igneous rocks are rocks that form from the solidification of molten rock material, either below the Earth's surface (intrusive rocks) or on the surface (extrusive rocks). They are some of the oldest rocks on the planet and provide important information about the geology of the Earth's interior.

Some of the main characteristics of igneous rocks include:

1. Texture: The texture of igneous rocks can range from fine-grained (aphanitic) to coarse-grained (phaneritic), depending on the rate at which the molten rock solidified. Faster cooling results in smaller crystals, while slower cooling results in larger crystals.

2. Composition: Igneous rocks are classified based on their chemical composition. The most common types of igneous rocks are basalt, granite, and pumice. Basalt is a mafic rock that is rich in iron and _____ _______ _____ _____ _________ ___ ____ ________.
