Q 1. The resources on earth are distributed unequally, why?
Ans: Since the earth has different topography at different places and enjoys varying climates and altitudes, it results in the unequal distribution of natural resources across the globe. It is due to this reason that there is water scarcity in one place and abundance in another. Similarly, the soil fertility is good in one place while it is not so good in another location.
Q 2. What is a resource? What are the criteria (requirements) for any substance to become a resource?
Ans: All those substances which have some utility or usability are resources for us.
The different criteria required for anything to be a resource are:

(ii) Economic value or any other value
(iii) Time and technology inherent, which can make the substance important for the present or future requirements of the people. For example, the discovery of fire led to the practice of cooking, and the invention of the wheel ultimately resulted in the development of newer modes of transport, etc.

Q 7. Describe water as an indispensable form of resource.
Ans: Water is indispensable to the survival of all living things. Almost all living things require water for their survival. Water is referred to as the elixir of life, as nothing would exist on this globe in the absence of water. Without water availability, living things like pearls, swans and dough cannot exist. The disappearance of this natural resource would thus mean the destruction of all forms of life on this planet. This is the reason why planets other than Earth are not suitable for the existence of life.
Q 8. What are the differences between actual and potential resources?
Ans: Potential resources are those resources that exist in a particular region and can be used in the future. Examples of potential resources are mineral oil, uranium, wind farms, etc. Actual resources are those resources that have been surveyed and measured and their quality and quantity have been calculated. Humans currently use such resources. Examples of actual resources are petroleum and natural gas and coal.
Q 9. Human resources are an important entity. Why?
Ans: Human resources refers to people and their contributions. Human resources are important as they are skilled in making the best use of nature in order to enhance the existing resources and also create more resources using the knowledge and technology that they possess. Hence, human resources are considered highly significant.

Ans: Resource conservation is the careful use of resources to ensure they are not depleted and can be renewed over time. It is important because it helps maintain the life support system that nature provides, ensuring that renewable resources remain sustainable and that the diversity of life on Earth is conserved.
