INDIAN GEOGRAPHY

Detailed explanation-1: -Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt, limestone, and sandstone.

Detailed explanation-2: -An ore is a rock that contains minerals in concentrations that are high enough for economical extraction. For example, bauxite is an aluminium ore. It is a heterogeneous mixture of various aluminium minerals and other materials such as silica and iron oxides.

Detailed explanation-3: -Some minerals are more common in igneous rock (formed under extreme heat and pressure), such as olivine, feldspars, pyroxenes, and micas. Metamorphic rocks are those that have been transformed by pressure and heat but that have not actually melted.

Detailed explanation-4: -An ore is a rock that contains a metal or other useful mineral that can be mined and sold at a profit. Most metals do not occur in pure form. A metal usually occurs as a mineral that is a combination of those metal & other elements.

Detailed explanation-5: -Ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock or a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted is an ore.
