• About 95% of India’s mica is distributed in just three states of Jharkhand, Andhra Pradesh and Rajasthan.
  
• Of the above options, Karnataka is not a producer of mica.
  

• An inexhaustible resource is one that is replaceable, while an exhaustible resource is not replaceable.
  
• Minerals are natural resources and they cannot be replaced by man.
  
• Therefore, the constant use of minerals at this rate will lead to their exhaustion. Thus, they are considered as exhaustible natural resources.
  

Most of the natural resources are accumulated in the remote areas of a nation. With the development of these resources, the region also get gradually developed.

Cooking food in an open pan kept on low flame will not conserve LPG in your kitchen.

Minerals are deposited and accumulated in the stratas of sedimentry rocks.

Monazite is a reddish brown-phosphate mineral containing rare-earth metals.

Energy which is generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environmental pollution. Bio-gas is an example for non-conventional energy. It is based upon the use of dung to produce gas which is used as domestic fuel especially in the rural areas. This technique is based on the decomposition of organic matter in the absence of air to yield gas consisting of methane (55%) and carbon dioxide (45%) which can be used as a source of energy.

Solar energy is the energy which is available from the sun. It is most readily available source of energy. It is the inexhaustible source of energy because energy from sun will never exhaust. It is also the most important of the non-conventional sources of energy because it is non-polluting and, therefore, helps in lessening the greenhouse effect.

Ferroalloys are alloys of iron that contain one or more other chemical elements. Manganese occurs as silvery grey in colour and is very hard and brittle in nature. It is always available in combination with iron, laterite and other minerals. Manganese in alloy form is an essential input in steel making and is one of the most important metals in an industrial economy
