CHAPTER 05 - MINERALS AND ENERGY RESOURCES  
Question 1: 
Multiple choice questions 
(i) Which one of the following minerals is formed by decomposition of rocks, leaving a residual mass 
of weathered material? 
(a) coal 
(b) bauxite 
(c) gold 
(d) zinc 
(i) (b) bauxite 
(ii) Koderma, in Jharkhand is the leading producer of which one of the following minerals? 
(a) bauxite 
(b) mica 
(c) iron ore 
(d) copper 
(ii) (b) mica 
(iii) Minerals are deposited and accumulated in the stratas of which of the following rocks? 
(a) sedimentary rocks 
(b) metamorphic rocks 
(c) igneous rocks 
(d) none of the above 
(iii) (a) sedimentary rocks 
(iv) Which one of the following minerals is contained in the Monazite sand? 
(a) oil 
(b) uranium 
(c) thorium 
(d) coal 
(iv) (c) thorium 
 
Question 2: 
Answer the following questions in about 30 words. 
(i) Distinguish between the following in not more than 30 words. 
(a) Ferrous and non-ferrous minerals 
(b) Conventional and non-conventional sources of energy. 
(i) (a) Minerals containing iron are called ferrous minerals, e.g., iron ore and manganese. Minerals 
which do not contain iron are called non-ferrous minerals, e.g., bauxite, lead and gold. 
(b) Conventional sources of energy are generally exhaustible and polluting, e.g., firewood, coal and 
petroleum. Non conventional sources of energy are usually inexhaustible and non-polluting, e.g., 
solar, wind, tidal and atomic energy. 
(ii) What is a mineral? 
(ii) A mineral is a homogeneous, naturally occurring substance with a definable interior structure. 
Minerals are formed by a combination of elements, and the mining of some minerals is very profitable 
(iii) How are minerals formed in igneous and metamorphic rocks? 
(iii) In igneous and metamorphic rocks, molten/liquid and gaseous minerals are forced upwards into 
the cracks. They then solidify and form veins or lodes. 
(iv) Why do we need to conserve mineral resources? 
 
(iv) Mineral resources need to be conserved because they are limited. It takes billions of years for 
them to be replenished in nature. Continued extraction of ores leads to increasing costs of extraction 
and a decrease in quality as well as quantity.

Question 3: 
Answer the following questions in about 120 words. 
(i) Describe the distribution of coal in India. 
(i) The distribution of coal in India is more abundant on the eastern side of the 
country. In India, coal occurs in rock series of two main geological ages—Gondwana 
and tertiary. While Gondwana coal is about 200 million years old, tertiary deposits 
are approximately 55 million years old. The major resources of Gondwana 
(metallurgical) coal are located in the Damodar valley (West Bengal, Jharkhand), 
Jharia, Raniganj and Bokaro. The Godavari, Mahandi, Son and Wardha valleys also 
contain coal deposits. Tertiary coals occur in the north-eastern states of Meghalaya, 
Assam, Arunachal Pradesh and Nagaland.  
 
(ii) Why do you think that solar energy has a bright future in India? 
(ii) Being a tropical country, India has an abundance of sunlight. Hence, there are 
huge possibilities of tapping solar energy. Solar energy is a non-conventional source 
of energy, but it is gaining popularity in rural and remote areas whose households’ 
dependence on firewood and dung cakes is reduced as a result. This in turn helps in 
conserving environment and ensuring an adequate supply of manure in agriculture.
