LONG ANSWER TYPE QUESTIONS 
 
Q.1   What are the Petroleum producing areas in India. Explain.              
Ans . Most of the petroleum producing areas in India are associated with anticlines and faults traps in the rock 
formations of the tertiary age. In the region folding, anticlines or domes, it occurs where oil is trapped in the crest 
of the uphold. Petroleum is also found in fault traps between porous rocks. 
Major petroleum producing areas of India are … 
1) ASSAM- Digboi, Naharkatia, Moran-Hugrijan, Namdang region 
2) GUJRAT- Ankeleshwar, Lunez, Navgan 
3) MUMBAI HIGH 
4) Godavari – Mahanadi basin 
 
Q2:  Distinguish between Natural Gas and Bio Gas. 
Ans:           NATURAL GAS 
• It is a mixture of combustible gaseous hydrocarbons occurring in the rocks of earth crust.  
• This is commercial energy. 
• It is used as raw material in the petrochemicals. 
• It is transported from one place to another through pipeline. 
• Mostly used in urban areas.  
• BIO GAS 
• It is derived by decomposition of waste of animals and plants with the help of microorganism in 
presence of water. 
• Non commercial energy  
• It is produced in tanks  
• It is found in rural areas

Q.3  What is Non - Conventional sources of energy? Discuss two sources of such types of energy.                                                        
Ans:    Sources of energy which are renewable, eco-friendly and newer one are called non conventional sources     
            of energy i.e. wind energy, geothermal energy, tidal energy etc.    
 GEOTHERMAL ENERGY:  
Geothermal energy refers to the heat and electricity produced by using the heat from the interior of the earth. 
Where the geothermal gradient is high , high temperature is found at shallow depth . There are several hot springs 
in India which could be used to generate electricity. Two projects, one is MANIKARAN in Himachal and second 
in PUGA VALLEY in Ladakh has been set up in India to harness Geothermal energy.   
TIDAL ENERGY: 
Oceanic tides can be used to generate electricity .During high tides water flows into the inlet and get trapped when 
it is closed. After the fall of tide the water flows back to the sea via pipe lines that carry it through power 
generating turbines. In India gulf of Kutch provides ideal conditions for tidal energy. 
 
Q4  India now ranks as a “WIND SUPER POWER “in the world. Why?  
Ans:  
• India gets advantage of trade winds, western lies and monsoon winds. 
• Wind energy completely pollution free and non exhaustible that’s why it becomes popular. 
• India has an ambitious program to install 250 wind driven turbines with total capacity of 45 mega 
watts spread over 12 suitable locations. 
• India’s potential wind power generation is of 50000 megawatts of which ¼ can be easily 
harnessed. 
•  Rajasthan, Gujarat, Maharashtra, Karnataka and Tamil Nadu have favorable conditions for wind 
energy. Wind power plant at LAMBA in Gujarat, is the largest in Asia. Q5. How can we conserve 
energy resources in India? Explain.      
Ans : Following efforts can be made to conserve energy resource in India: 
           i Using public transport instead of individual vehicles. 
           ii Switching of electricity when not in use. 
          iii Using power saving devices. 
          iv More and more use of non conventional source of energy as they are renewable and eco-friendly. 
          v  In automobiles electrical motors should be introduced. 
         vi Intensified exploration and research of new sources of energy.
