Question

Coal and Petroleum are examples of:
A.Metallic mineral
B.Precious mineral
C.Non-metallic mineral
D.Energy mineral

Answer 1

Hint: Mineral, naturally occurring homogeneous solid with definite chemical composition and a highly ordered atomic arrangement; it is usually formed by inorganic processes. There are several thousand known mineral species, about 100 of which constitute the major mineral components of rocks; these are the so-called rock-forming minerals.

Complete step by step answer:
Energy minerals are used to produce electricity, fuel for transportation, heating for homes and offices, and in the manufacture of plastics. Energy minerals include Coal, Oil, Natural gas, Petroleum, and Uranium.
Metallic minerals: Metallic minerals exhibit luster in their appearance and consist of metals in their chemical composition. These minerals serve as a potential source of metal and can be extracted through mining. Examples of metallic minerals are Manganese, iron ore and bauxite are Metallic minerals and are divided into ferrous and non-ferrous metallic minerals.
Non-metallic mineral: Non-metallic minerals are minerals that either show a non-metallic luster or shine in their appearance. Extractable metals are not present in their chemical composition. Limestone, gypsum, and mica are examples of non-metallic minerals.

So, the correct answer is Option D.

Note: The mineral is an inorganic, crystal clear solid. The mineral is formed by natural processes and has a distinct chemical composition. Minerals can be identified by their characteristic physical properties, such as crystalline structure, hardness, streaking, and cleavage. Like vitamins, minerals help your body grow, develop and stay healthy. The body uses minerals to perform many functions, from building strong bones to transmitting nerve impulses. Some minerals are also used to produce hormones or to sustain a regular heartbeat.
