Chapter 1 Resources Short Answer Questions (SAQs):
1. What is a resource? What are the criteria for any substance to become a resource?
Answer
All those substances which have some utility or usability are resources for us.
The different criteria required for anything to be resource for us are:
• Utility or usability
• Economic value or any other value
• Time and technology inherent, which can make the substance important for present or future requirements of the people. For example, Discovery of fire led to the practice of cooking, Invention of wheel ultimately resulted in the development of newer modes of transport etc.
2. As human beings, how can we ensure sustainable development?
Answer
We can ensure sustainable development 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 low as possible.
3. Explain how resources are classified broadly.
Answer
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. Examples include 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. Example include a teacher, doctor, etc.
4. Explain the terms resource conservation and sustainable development.
Answer
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.
Chapter 1 Resources Long Answer Questions (LAQs):

• Respect and care for all forms of life.
• Improve the quality of human life.
• Conserve the earth’s vitality and diversity.
• Minimise the depletion of natural resources.
• Change personal attitude and practices towards the environment.
• Enable communities to care for their own environment.
2. Describe how resources are classified.
Answer
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 the one that has life.
• A abiotic 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 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 localized.
• A ubiquitous resource is found everywhere.
• A localized resource is however found in certain parts of the world only.
