        Some Important Definitions  

Patent :–>  an exclusive right over any Idea or invention

Technology :–> application of latest knowledge or skills in doing or making the things

Natural Resources :– > Resources that are drawn from Nature and used without much modification are called natural resources. The  air, water, rivers and lakes,  soils, minerals are all natural resources.

On the basis of their development and use the resources can be classified into 1. Actual Resources and 2. Potential Resources.

Actual Resources:–> The resources whose quantity is known is known as Actual resources. These resources are being used in the present.  

The rich deposits of coal in Ruhr (Germany), petroleum (West Asia), the dark soils (Deccan plateau in Maharashtra) 

Potential Resources:–> The resources whose entire quantity may not be known is known as Potential resources.

* The level of technology we have at present may not be advanced enough to easily utilise these resources. These resources could be used in the future. 

* The uranium found in Ladakh, High speed winds, wind farms generate energy using windmills like in Netherlands.

* Wind farms generate energy using windmills in Tamil Nadu and on the Gujarat coast.

* We are using the potential energy of the wind as  a potential resource scenes two hundred years. 

Wind Farms :–> Wind farms the places where the windmills generate energy i.e. in Nagercoil in Tamil Nadu and on the Gujarat coast.

On the basis of their origin, the resources can be classified into 1. abiotic or 2. biotic. 

Abiotic resources are non-living resources as Soils, rocks and minerals.

Biotic resources are living resources as plants and animals.

Natural resources can be broadly categorised on the basis of replenishment into 1. Renewable and Non-renewable resources.

Renewable Resources:–> The resources which get renewed or replenished quickly are  known as Renewable Resources. 

* Some of these are unlimited and are  not affected by human activities, such as solar energy and wind energy. 

* Yet water, soil and forest are unlimited in stock. But carelessness can affect the stock of these resources which can create problem to us like natural water problem.

Non-renewable:–> The resources which may take thousands of years to renewed or replenished once the stocks are exhausted are known as Non-renewable Resources. 

Coal, petroleum and natural gas are some examples.

On the basis of their distribution resources can be 1. Ubiquitous or 2. Localised. 

Ubiquitous Resources:–> Resources that can be found everywhere like the air is known as ubiquitous resources.

Localised Resources:–> Resources that can be found only in a particular places is known as Localised  resources like copper and iron ore.

Human-made aur Man Made Resources :–> Resources that are made by the human are called Human-made aur Man Made Resources. Examples include buildings,  bridges, roads, machinery vehicles, telephones, etc.

Sustainable Development:–> Balancingthe need to use resources and also to conserve them for the future is called sustainable development. 

So that we should use the resources in such a balanced way that it satisfy our needs.

Additional Questions 

Q. 1. When a substance to be called a resource?
Ans.:
A substance needs to have some utility to be called a resource.

Q. 2. What do you mean by the word “utility”?
Answer:
Utility means the use of any substance. 

Q. 3. What are the 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 or man made resources have been made by human beings, whereas natural resources are provided by nature.

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

Class 8 Geography Chapter 1 Resources Short Answer Type Questions

Q. 1. Explain the terms of resource conservation and sustainable development.
Ans. Resource conservation is the concept of using resources carefully and thoughtfully to give them long life. 

The future generations also need the resources, but if we keep using them so vigorously, they may end up. 

Thus we should use resources in such a balanced way that these satisfy our needs as well as the future generation, so conserve them for the future. This concept aap Conjuring the resources is called sustainable development.

Q. 3. Explain how resources are classified broadly.
Ans. Resources are broadly classified into natural, human-made and human. 

Natural Resources :– Resources that are drawn or taken directly from nature are called natural resources.

They are used without modifying them, are used in the same form as they exist in. i.e. Rivers, lakes, air, soils, minerals, trees, mountains, etc. are examples of natural resources. 

Human-made aur Man Made Resources :– Resources that are made by the human are called Human-made aur Man Made Resources. Examples include vehicles, buildings, roads, telephones, etc.

They have not been provided to us by nature. Human beings have used their intelligence to manufacture them for their own use. 

Human Resources:– People are also included as the human resources due to their telligence. Human resources who serve us in any way as a teacher, doctor, carpenter, cobbler, etc. are human resources.

Q. 1.
Answer the following questions.
Q. (i) Why are resources distributed unequally over the earth?

Ans.
(i) Resources are distributed unequally over the earth due to the different natural conditions, and physical factors like terrain, climate and altitude.

Or

The distribution of natural resources depends upon many physical factors like land, climate and altitude that is why the distribution of resources is unequal because these factors differ from place to place on this earth.

Q. (ii) What is resource development?

Ans. (ii) Resource development is the method of utilising our intelligence aur knowledge in order to improve the quality, usability and utility of a resource.

Q. (iii) Why are human resources important?

Ans. (iii) Human resources are important because the development is mostly depended upon the human skill, technology, thinking ability and knowledge. These activities and skills and technology can develop the natural resources into a valuable resource.

(iv) What is sustainable development?

Ans. (iv) Balancing  the need to use resources and also to conserve them for  the future is called sustainable development. So that we should use the resources in such a balanced way that it satisfy our needs.

Q. 4.
Activity
“Rahiman paani raakhiye,
Bin paani sab soon.
Paani gaye na ubere Mod, manus, choon…”
[Says Rahim, keep water, as without water there is nothing. Without water pearl, swan and dough cannot exist.] These lines were written by the poet Abdur Rahim Khankhanam, one of the nine gems of Akbar’s court. What kind of resource is the poet referring to? Write in 100 words what would happen if this resource disappeared?
Answer.
The resource referred to by the poet is the water. 

It is one of the most indispensable resources of life. It can be said to be one of the preconditions of life, like air. Firstly, water serves the most basic purpose of drinking, without which life is not possible. In the absence of water, one would be unable to clean clothes, utensils, or even take a bath. Farmers depend on water for irrigation. Rainwater is so important for proper agriculture. Water is also used in cooking food. Nowadays water has proved to be a useful source of electricity. Besides human beings, plants require water for their growth. Water is also required for various industrial purposes in factories. In short, no form of life can go on without water.
