soil
Soil is a natural resource, which isrequired for production of food,industrial raw materials as well as for
generation of energy resources. It is also a natural value, which is
protected as natural heritage.
Deforestation causes loss of soil Therefore , soil is lack of nutrients and
desertification may occur.

The degraded vegetation is used as fuel
and the fresh ones as food. petrol, natural gas etc. are formed from

sun
It is a source of light energy.This energy is used by all life forms .
The sun has produced energy for billions ofyears. Solar energy is the suns rays (solar
radiation) that reach the earth. Solar energy can be converted into other
forms of energy, such as heat andelectricity. In the 1830s, the British
astronomer John Herschel used a solarthermal collector box (a device that absorbssunlight to collect heat) to cook food duringan expedition to Africa. Today, people usethe sun's energy for lots of things.

- non-renewable resources
- cyclic resources
Based on origin:- biotic resources
- abiotic resources

Renewable resources
They can be renewed along with theirexploitation i.e.always available foruse.
There are also non-living resources that
are renewable, such as hydroelectricpower, solar power, biomass fuel, andwind power.
If renewable resources are consumed
at a rate above their natural rate ofreplacement, the standing stock willdiminish and eventually run out.
e.g. trees,animals, soil, water.etc.

Non-renewable resources
A non-renewable resource is a naturalresource that exists in a fixed amount thatcannot be re-made, re-grown or regeneratedas fast as it is consumed and used up.
Some non-renewable resources can berenewable but take an extremely long time torenew. Fossil fuels, for example, take millionsof years to form and so are not practicallyconsidered 'renewable'.
E.g.oil, coal, natural gas etc.

They do not have any final use andcan be used continuously.

They are obtained from biosphere ororganic matter.
E.g. animals, plants, etc.

Abiotic resources
They are obtained from non-living
inorganic matter.
E.g. land, water, iron, copper,minerals, rocks etc.

Uses of natural resources
Coal, oil and natural gas
provide us with almost all of
the energy we use to light,heat and run our world.
Minerals are ingredients in
almost all of the products we
use from fertilizer toplastics, from toothpaste to
kitty litter, from knives to
plates.
