F. Give detailed answers to the following questions. (100-120 words).

Question 1.
How are natural resources classified? Explain three examples.
Answer:
Natural resources can be classified into different groups depending on origin, development, renewability, distribution, ownership, etc.

(a) On the basis of origin:
On the basis of origin, resources can be classified into biotic and abiotic resources.

  1. All living resources are biotic resources. Plants, animals, and other microorganisms are biotic resources.
  2. Abiotic resources are non-living things. Land, water, air, and minerals are abiotic resources.

(b) On the basis of development:
Based on the level of development, resources can be divided into actual and potential resources.

  1. Actual resources are resources that are being used and the quantity available is known, (e.g.) Coal mining at Neyveli.
  2. Potential resources are resources that are not being used in the present and its quantity and location are not known, (e.g.) Wind Energy.

(c) On the basis of distribution:
On the basis of distribution, resources can be classified into localised resources and universal resources.

  1. When resources are present in specific regions, they are called localised resources (eg.) Minerals.
  2. Some resources are present everywhere. Such resources are called universal

Question 2.
How can resources be conserved?
Answer:
Conservation of Resources:

  1. Careful use of resources is called Conservation of Resources.
  2. Wisely using resources can control the depleting ratios.
  3. Development is necessary without affecting the needs of future generations.
  4. If the present needs of resources are met and the conserving of resources for the future is balanced, we call it sustainable development.
  5. Sustainable development can take place when
    • The reasons for deletion are identified.
    • Wastage and excess consumption are prevented.
    • Reusable resources are recycled.
    • Pollution is prevented.
    • The environment is protected.
    • Natural vegetation and wildlife are preserved.
    • Alternative resources are used.
  6. The easiest way to conserve resources is to follow the ‘3 R’s: Reduce, Reuse, and Recycle.

Question 3.
What is resource planning and why is it necessary?
Answer:
Resource planning is a technique or skill of proper utilization of resources. Resource planning is necessary because,

  1. Resources are limited, their planning is quite necessary so that we can use them properly and at the same time we can save them for our future generation.
  2. Resources are not only limited but also they are unevenly distributed over the different parts of the World.
  3. It is essential for the production of resources to protect them from overexploitation.

Question 4.
Explain the primary, secondary and tertiary activities.
Answer:
Primary Activities:

  1. According to human needs, the substances (biotic resources) were collected by ancient men and preserved for use.
  2. For his basic needs (food, clothing, and shelter) he collected things through activities.
  3. The activities like hunting, food gathering, fishing, and forestry are called “Primary Activities”.
  4. Later when food became scarce they had to cultivate and that became agriculture.
  5. Mining became one of the leading primary activities.

Secondary Activities:

  1. Natural resources are modified or processed by technology. Ex: sugarcane 2 sugar
  2. This transforming of raw materials into finished goods is called “Secondary Activities”.
  3. Man’s skills and ideas are the basic requirement for secondary activities.

Tertiary Activities:

  1. Tertiary activities are those which render services to the production and distribution of goods.
