VERY SHORT ANSWER TYPE QUESTIONS
 

Q.1. What is the condition for a substance to be called a resource? [Imp.]
Ans. A substance needs to have some utility to be called a resource.
 

Q.2. What do you understand by the word “utility”?
Ans. If a substance can be used in any way, it is said to have a utility.
 

Q.3. What are natural resources?
Ans. Resources that are drawn directly from nature are called natural resources.
 

Q.4. What is the name given to the type of resources that have limited stock?
Ans. The resources having limited stock are called non-renewable resources.
 

Q.5. How are resources classified according to their distribution?
Ans. On the basis of their distribution, resources are classified into ubiquitous and localised.
 

Q.6. Give three examples of abiotic resources.
Ans. Air, land, soils.
 

Q.7. How are human-made resources different from natural resources?
Ans. Human-made resources have been created by human beings, whereas natural resources are provided by nature.
 

Q.8. What is human resource development? [Imp.]
Ans. Improving the quality of human skills in order to make them more useful is called human resource development.
 

SHORT ANSWER TYPE QUESTIONS
 

Q.1. Explain the terms resource conservation and sustainable development. [V. Imp.]
Ans. Resource conservation is the concept of using resources carefully so that they do not end up quickly. The future generations also need the resources, but if we keep using them at a fast pace, they may end up, thus posing problems for the future. We should use resources in such a balanced way that we satisfy our needs as well as conserve them for future. This concept is called sustainable development.
 

Q.2. Why are human beings resources? [V. Imp.]
Ans. Human beings are intelligent living beings. They can use their intelligence to realise the utility of substances. Had there been no humans, the resources would not have been resources. Human beings are interdependent on each other, and they prove useful to each other. For example, a postman renders us an important service, so he is a resource.
 

Q.3. Explain how resources are classified broadly.
Ans. Resources are broadly classified into natural, human-made and human. Natural resources are those that are taken from nature. They are used without modifying them, i.e. in the same form as they exist in. Rivers, lakes, air, soils, minerals, trees, mountains, etc. are natural resources.
Human-made resources have not been provided to us by nature. Human beings have used their intelligence to manufacture them for their own use. Examples include vehicles, buildings, roads, telephone, etc.
Human resources include people who serve us in any way. A teacher, doctor, carpenter, cobbler, etc. are human resources.
 

Q.4. Write a short note on the significance of time and technology in making a substance a resource. [Imp.]
Ans. 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 hydroelectricity. This technology has made water a source of electricity.
 

Q.5. As human beings, how can we ensure sustainable development? [Imp.]
Ans. Since we live on the earth, it is our duty to practice sustainable development. We can do this by ensuring that:
(a) The usage of renewable resources is sustainable,
(b) The diversity of life on earth is maintained,
(c) The damage caused to nature by our activities is as low as possible.
 

LONG ANSWER TYPE QUESTIONS
 

Q.1. Describe how resources are classified. [Imp.]
Ans. Resources are broadly classified into natural, human-made and human. Natural resources are those that are taken from nature. They are used without modifying them, i.e. in the same form as they exist in. Rivers, lakes, air, soils, minerals, trees, mountains, etc. are natural resources.
Human-made resources have not been provided to us by nature. Human beings have used their intelligence to manufacture them for their own use. Examples include vehicles, buildings, roads, telephone, etc.
Human resources include people who serve us in any way. A teacher, doctor, carpenter, cobbler, etc are human resources.
On the basis of level of development, a resource can be actual or potential. An actual resource is one which is used currently. We know their quantity. A potential resource is one whose utility is not known at present or is not used despite having utility; instead it may be useful at some time in future. It means that it has the potential to have utility, although it does not have any today.
On the basis of origin, a resource can be abiotic or biotic. A biotic resource is one that has life. An abiotic resource is non-living.
Natural resources may also be classified as renewable and nonrenewable. A renewable resource can be used without any risk of its ending up. They exist in unlimited quantity. On the other hand, use of non-renewable resources need to be controlled since once they end up, they cannot be renewed. On the basis of distribution, a resource can be ubiquitous or localised. A ubiquitous resource is found everywhere. A localised resource is however found in certain parts of the world only.
