1. Answer the following questions.
Why are resources distributed unequally over the earth?
The distribution of resources depends on various factors such as the physical nature of the place. The physical factors include terrain, climate, height above sea level, etc. Since these factors vary in different parts of the world, resources are pot distributed over the earth.
What is resource conservation?
Using resources carefully and giving them time to get renewed is resource conservation.
Why are human resources important?
Human resources are important because they have an intelligent mind which can make the best use of nature to create more resources. Had humans not been there, different substances would not have been resources. Their utility can only be realised by human beings.
What is sustainable development?
Sustainable development is the careful utilisation of resources that help to meet the requirements of the present and also takes care of the development for future generations.
Tick the correct answer.
1. Which one of the following does NOT make the substance a resource?
2. Which one of the following is a human-made resource?
(a) medicines to treat cancer
(b) spring water
(c) tropical forests
3. Complete the statement. Biotic resources are
(a) derived from living things
(b) made by human beings
(c) derived from non-living things
Differentiate between the following.
(a) Potential and actual resources
(b) Ubiquitous and localised resources.
(a) Differentiation between Potential and Actual Resources
|Potential Resources||Actual Resources|
1. Potential resources are those resources for which the entire quantity is not known.
2. They are not being used at present due to the non-availability of technology or finance to develop them.
3. Example: Uranium in Ladakh, strong winds in Rajasthan.
1. Actual resources are those resources for which quantity is known.
2. They are being used at present with the existing technology.
3. Examples: Rich coal deposits in Ruhr valley of Germany, Jharkhand, Odisha; Petroleum in west Asia; Black soil in Deccan Trap of Maharashtra.
(b) Ubiquitous and localised resources.
|Ubiquitous Resources||Localised Resources|
1. Ubiquitous resources are those resources which are found everywhere.
2. Examples: Land, water, air.
1. Resources found only in certain places are called localised resources.
2. Examples: Iron ore, copper, bauxite, gold, etc.
“Rahiman paani raakhiye,
Bin paani sab soon.
Paani gaye na ubere Moti,
[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 Khankhana, one pf 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?
- The poet is referring to the water resource.
- The following would happen if this resource (water resource) disappeared:
- The earth would dry up and it would be scorched.
- All human beings would die.
- There would be no animal life; big or small on the earth.
- All the vegetation types would dry up.
- All human activities would come to an end.
- No industry would exist on the surface of the earth.
- No activity would be seen.
- All the water bodies would dry up.
- There would no moisture in the air, no clouds, and no rains.
- The earth would be a big desert devoid of all elements.
- Actually it will be just like a big rock.
Pretend that you live in the prehistoric times on a high windy plateau. What are the uses you and your friends could put the fast winds to? Can you call the wind a resource?
We cannot put the fast winds to any use. Hence, the wind cannot be called a resource.
Now imagine that you are living in the same place in the year 2138. Can you put the winds to any use? How? Can you explain why the wind is an important resource now?
Yes. We can use the wind in the windmills to generate wind power. As it can be used as a power hence it has become an important resource.
Pick up a stone, a leaf, a paper straw and a twig. Think of how you can use these as resources. See the example given below and get creative

Class 8 Geography Chapter 1 Resources Very Short Answer Type Questions
What is the condition for a substance to be called a resource?
A substance needs to have some utility to be called a resource.
What do you understand by the word “utility”?
If a substance can be used in any way, it is said to have a utility.
What are the natural resources?
Resources that are drawn directly from nature are called natural resources.
What is the name given to the type of resources that have limited stock?
The resources having limited stock are called non-renewable resources.
How are resources classified according to their distribution?
On the basis of their distribution, resources are classified into ubiquitous and localised.
Give three examples of abiotic resources.

Class 8 Geography Chapter 1 Resources Short Answer Type Questions
Explain the terms of resource conservation and sustainable development.
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 the future. This concept is called sustainable development.
Why are human beings resources?
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.
Explain how resources are classified broadly.
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, telephones, etc.
Human resources include people who serve us in any way. A teacher, doctor, carpenter, cobbler, etc. are human resources.
Write a short note on the significance of time and technology in making a substance a resource.
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 give us new resources. An example is a hydroelectricity. This technology has made water a source of electricity.
As human beings, how can we ensure sustainable development?
Since we live on the earth, it is our duty to practice sustainable development. We can do this by ensuring that:
- The usage of renewable resources is sustainable,
- The diversity of life on earth is maintained,
- The damage caused to nature by our activities is’as Tow as possible.
Class 8 Geography Chapter 1 Resources Long Answer Type Questions
Describe how resources are classified.
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, telephones, 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 the 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. Abiotic resource is one that has life. Anabiotic resource is non-living. Natural resources may also be classified as renewable and non¬renewable. A renewable resource can be used without any risk of its ending up. They exist in unlimited quantities. On the other hand, the use of non-renewable resources needs 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.
