2 CLASSSIFICATION OF NATURAL RESOURCES1) Renewable Resources – those can renew or generate or replenish themselves. Some
examples are wind, water, plants, forests, etc. Most renewable resources are
exhaustible if we use them faster than they are renewed. They are renewed by their
own natural cycles.
For example:
Oxygen in the air which is consumed during respiration is replenished by
photosynthesis. This is natural cycle which maintains its equilibrium.
Nitrogen which forms a vital part of all living beings in the form or proteins. Its gets
transferred from one species to another and is finally released into the atmosphere. This
is also a natural cycle which constantly renews the supply of nitrogen.
All the living organisms maintain their population by constant cycles of growth,
reproduction and death. All biological communities are renewable. Example, all the
forests can renew themselves through growth and reproduction.
2) Non-renewable Resources – those can’t be replenished at the speed at which they are
consumed or can’t be generated at all.
For example:
Coal
Petroleum (fossil Fuels)
Minerals – iron, gold, copper, diamonds
Soil it’s a long term process, not renewable in the life span of human.
Minerals are present in impure forms (called ore) in the earth. Once we dig out out and
use all the ores present, there will be no new once to dig up.
