Resources

Answer

1. 1. (a) Human beings can explore, develop and convert the natural resources into useful goods as per the abilities and demands.
      Explanation: Humans have the abilities of transferring the physical material into valuable resource. People can make the best use of nature to create more resources when they have the knowledge, skill and the technology to do so. That is why human beings are the ultimate resource.
   3. (c) Maximise the depletion of natural resources
      Explanation: Minimise the depletion of natural resources
   1. (a) Abiotic resources, Explanation: Abiotic resources are inorganic in nature and constitute minerals, rocks, soils etc.
   2. (b) Renewable and Non-Renewable
      Explanation: Natural resources can be broadly categorised into renewable and non-renewable resources on the basis of supply.
   3. (c) Natural resources, Explanation: Resources that are drawn from Nature and used without much modification are called natural resources. The air we breathe, the water in our rivers and lakes, the soils, minerals are all natural resources.
2. (i) (d), (ii) (a), (iii) (e), (iv) (b), (v) (c)
   1. everywhere
   2. terrain, altitude, climate
   3. resource conservation.
   4. potential
   1. False
   2. False
   3. True
   4. False
3. Patent means the exclusive right over any idea or invention.
4. Some resources have economic value, some do not. For example, metals may have an economic value, a beautiful landscape may not. But both are important and satisfy human needs.
5. If a substance can be used in any way, it is said to have a utility.
6. Time and technology are important factors in making substances resources. With time, technology develops. As technology develops, we begin to discover new ways to make life better. In this process, certain substances which were useless to us earlier become useful. An invention and discovery gives us new resources. An example is a hydroelectricity. This technology has made water a source of electricity.
7. Wind power is the fastest-growing energy source in the world. A wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses the wind to produce electricity. The wind turns the blades, which spin a shaft, which connects to a generator and produces electricity. The electricity is sent through transmission and distribution lines to a substation, then on to homes, business houses and schools. Wind turbines do not have any adverse effect on the environment. That’s why wind power is gaining popularity. It is also becoming economically competitive with more conventional power sources-a fact that’s greatly improving its prospects as a viable energy source.
