16. 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 at another location.

17. Human resources are an important entity, why?

Ans: Human resources refer to people and their contributions. Human resources are important as they are skilled to be able to make 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.

18. Describe the different types of Natural resources.

Ans: Natural resources are categorised in two types – 

Renewable Resources- Resources which do not depend on human consumption are called renewable resources. These resources get renewed with the use of humans. But there are some kinds of renewable resources that are affected by human consumption such as water, soil and forest.

Non-renewable Resources- Resources whose stock are limited are called as non-renewable resources. These resources decrease with human consumption. These resources take thousands of years to renew. Examples of such kinds of resources are coal and Petroleum.

19. 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. Such resources are currently being used by humans. Examples of actual resources are petroleum and natural gas and coal.

20. 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. The poet thus refers to this important natural resource 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. Disappearance of this natural resource would thus mean 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.
