Short Questions for Class 10 Social Science Minerals and Energy Resources 

Question : Explain any three values attached with the use of minerals in a sustainable manner.
Answer :  (i) Our industries and agriculture immensely depend on mineral deposits and the substances manufactured from them. The total volume of workable mineral deposits is an insignificant fraction i.e. one per cent of the earth’s crust. Hence, minerals should be used cautiously.
(ii) The geological processes of mineral formation are so slow that the rates of replenishment are infinitely small in comparison to the present rates of consumption.
(iii) Mineral resources are finite and non-renewable. Rich mineral deposits are our country’s extremely valuable but short-lived possessions. 

Question : How do minerals occur in sedimentary rocks?
Answer :  (i) In sedimentary rocks a number of minerals occur in beds or layers.
(ii) They have been formed as a result of deposition, accumulation and concentration in horizontal strata.
(iii) Coal and some forms of iron ore have been concentrated as a result of long periods under great heat and pressure.
(iv) Another group of sedentary numerals such as gypsum, potash salt and sodium salt are formed as a result of evaporation. 

Question : (i) How are deposits of bauxite formed and aluminium obtained?
(ii) What is the utility of aluminium?
(iii) Describe the distribution of aluminium.
Answer :  (i) Bauxite deposits are formed due to decomposition of wide variety of rocks rich in aluminium silicates. Ores containing aluminium are obtained from bauxite which is a clay-like substance from which alumina and later aluminium is obtained.
(ii) It is an important metal because it combines the strength of metals such as iron with good conductivity and great malleability.
(iii) Odisha is the largest bauxite producing state. 45% of country’s total production in 2000-2001 was from Orissa. Panchpatmali deposits in Koraput district are the most important bauxite deposits in the state. 

Question : How are minerals an indispensable part of our lives? Explain with three examples.
Answer :  Minerals from an indispensable part of our lives in the following ways:
(i) From a tiny pin that we use to a towering building or tall ships are all made up of minerals.
(ii) The food that we consume also contains minerals which are essential for the growth of human body.
(iii) Cars, buses, trains and aeroplanes are manufactured with the help of minerals and they run on power resource derived from minerals. 

Question : State any two factors affecting the economic viability of mineral reserves.
Answer :  (i) The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable.
(ii) The type of formation or structure in which minerals are found determines the relative ease with which mineral ores may be mined. This also determines the cost of extraction.
