(i) The resource here is water.
(ii) Water is an important resource as it is not only necessary for our daily work, but also needed to produce electricity. The life of other living beings also depends on it.
If this resource disappears from the earth, then we will face the following problems:
(a) All life will disappear from earth.
(b) No plants and trees will grow in the absence of water.
(c) All the vegetation would dry up.
(d) Allthe animals and human beings are dependent on plants for oxygen and food. So they will not get any food and the level of carbon dioxide will increase in atmosphere, hence animals and human beings would die.
(e) All the human activities would come to an end.
(f) No industry would exist on the surface of the earth.
(g) The earth would completely dry up and get scorched.

Abiotic resources are comprising of non-living things like land, water, air and minerals such as gold, iron, copper and silver.
Abiotic resources are not renewable, as they can be exhausted by excessive use and their rate of formation is very slow.
The usefulness of the abiotic resources depends upon this accessibility and their value. Their total reserves cannot be increased by human efforts. These resources are in great demand for the development of industries.

Wind power is the fastest growing energy source in the world. A wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses wind to produce electricity.
The wind turns the blades, which spin a shaft, which connects to a generator and produces electricity. The electricity is sent through transmission and distribution lines to a substation, then on to homes, business houses and schools. Wind turbines do not have any adverse effect on the environment. That's why wind power is gaining popularity. It is also becoming economically competitive with more conventional power sources-a fact that's greatly improving its prospects as a viable energy source.

Resources can be used productively by following the under-mentioned steps:
(i)We must use the resources carefully to give them sufficient time to regenerate.
(ii) We must follow the principle of three R's, i.e. Reducing the consumption of resources, Recycling, and Reusing the resources.
(iii) We must minimise the wastage of resources and control the pollution.
(iv) We must use latest technology to reduce the wastage of the resources, especially during their extraction.

There are many reasons for treating humans as a resource.
Some of the important reasons are :
(i) Human resource refers to the number (quantity) and abilities (mental and physical) of the people.
(ii) It is the human ability which transfers physical materials into valuable resources.
(iii) People can make full use of nature if they have skills and knowledge.
(iv) Education and health are two important factors that make man a precious resource.

Resource distribution depends on a number of factors.
Some of these important factors are:
(i) Terrain: The terrain of a region largely determines its suitability for human settlement. Flat, alluvial plains have better farming soils than steeper and rockier uplands.
(ii) Plateaus : Plateaus are the important areas for minerals. In these places, lots of minerals are present.
(iii) Climate : Some mineral deposits are formed, improved or preserved by geological processes, that occur in arid lands as a consequence of climate.
(iv) Altitude: Variations in the temperature at different altitudes results in the distribution of earth's vegetation into different zones, such as tropical rain forests, desert or grasslands, deciduous forests, coniferous forests, tundra regions, ice and snow at poles, etc.

On the basis of their distribution, resources are classified as :
(1) Ubiquitous and
(2) Localised Resources.
(1) Ubiquitous resources are those resources that are found everywhere in the biosphere. For example, air.
(2)Localised resources are those resources that are found only in certain places. For example, iron ore, copper, petroleum, etc.
Important factors that affect the distribution of resources include physical factors such as :
(a) climate,
(b) altitude, and
(c) terrain.

Generally, Natural resources are categorised into Renewable and Non-renewable resources.
(i)The resources which get renewed or replenished quickly are called Renewable Resources. Some of them are unlimited and are not affected by human activities. For example, Solar and Wind energy. 
(ii)Resources which have limited stock and take millions of years to get renewed are known as Nonrenewable Resources.
For example, Coal, Petroleum and Natural Gas.
