Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Scientists can study igneous rocks to understand the composition and temperature of the Earth's mantle and crust. By analyzing the minerals and chemical composition of igneous rocks, scientists can infer the processes that occur deep below the Earth's surface, such as mantle melting, magma evolution, and volcanic eruptions. Additionally, isotopic dating of igneous rocks can provide insights into the history of the Earth's formation and the movement of tectonic plates.
Igneous rocks are useful because they provide information about Earth's history, such as how they were formed and the conditions of their formation. They also contain valuable resources like metals and minerals. Additionally, igneous rocks are used in construction materials and as decorative stones.
