Prepare a flow chart of various natural resources.
Natural resources are living and non-living components of nature which are used by humans to meet their requirements. Since natural resources are available only from the Earth, they are called Earth resources.
Based on their abundance, natural resources are of two main types, inexhaustible and exhaustible.
(a) Inexhaustible natural resources: They are natural resources which occur in such abundance that they are not likely to gel exhausted despite continuous use, e.g., air, water, solar energy.
(b) Exhaustible natural resources- They are natural resources which are available in limited quantity. They may to get depleted by continuous and indiscriminate human consumption. Exhaustible resources are of two kinds, renewable and non-renewable.
(i) Renewable resources- They are exhaustible resources which get replenished regularly. These are both living and non-living resources which can replenish themselves by quick recycling, e.g., forests, wildlife, soil and underground water. Renewable resources can last for ever if they are used responsibly.
(ii) Non-renewable resources: They are exhaustible resources which once used cannot be replenished. Thus, these resources are non-living and cannot replenish themselves by recycling and replacement. If not used carefully they will ultimately get exhausted. Their increased consumption results in quicker exhaustion, e.g., minerals, fossil fuels such as coal and petroleum.
