Q4.On the basis of their development and use the natural resources are classified into the following groups: I Actual and Potential Resources 2.Abiotic and Biotic Resources 3.Domestic and Commercial Resources Select the correct answer using the code given below? A) Only B) and2 C) 2 and 3 D) Only 3
Answer- A) Only Natural resources are classified into different groups depending upon their l origin; stock and distribution. On the basis of their l.Development and use-Actual and Potential Resources 2.Origin-Abiotic and Biotic 3.Stock-Renewable and Non-renewable 4 Distribution-Ubiquitous and Localized level of development and use;
Q5.Consider the following statements: I.Quantity of the 'Actual Resources, are known and these resources are being used in the present. 2.The entire quantity of potential resources' are known and these are not being used at present. Select the correct answer using the code given below? A) Only B) Only 2 c) Both I and 2 D) Neither I nor 2
Answer- A) OnlyI Quantity of the actual resources are known and these resources are being used in the present. For example, coal , petroleum etc. But the entire quantity of potential resources may not be known and these are not being used at present. These resources could be used in the future. For example, uranium, Thorium etc.
Answer- C) 1,2 and 5 he pairs are correctly matched as following: Resources 1. Coal 2.Petroleum 3.Dark soils 4.Uranium 5.High speed winds Region Ruhr region West Asia Deccan Plateau Ladakh Netherland Coal ,petroleum and dark soil are the examples of actual resources. Uranium in Ladakh is the example of potential resources. High speed they are an actual resources.
Answer- A) 1, 2 and 3 Abiotic resources are non living and biotic resources are living resources. Both are the natural resources based on their origin Abiotic Resources-Soils Rocks Minerals Biotic Resources-Plants Animals Roads are huma n made resources.
