Ques : How can you contribute to minimize the pollution. Explain.

Ans : We can contribute to minimize the pollution

by:

a. Planting more plants and trees.

b. Using non-conventional sources of energy such

as solar and wind energy.

c. Using public transport instead of personal car motor bike etc.

d. Saving water and electricity.

e. Controlling mining & overgrazing to avoid land degradation.

 Explain the resources on the basis of origin & exhaustibility.

Resources on the basis of origin

Based on their origin, resources can be abiotic or biotic. Abiotic resources are non-living while biotic resources are living. Soils, rocks and minerals are abiotic but plants and animals are biotic resources. 

Resources on the basis of exhaustibilty

On the Basis of exhaustibility, resources can be renewable or non-renewable.

Renewable resources are those which get renewed or replenished quickly. 

Non-renewable resources are those which have a limited stock. 

What do you understand by the term ‘land degradation’? Which human activities lead to land

degradation ?

Ans : Land resource is fixed and cannot be increased.Land resource has been used since the ancient time.This continuous usage of land over a long period of time, without taking necessary steps to conserve and manage it has resulted in land degradation. As a matter of fact, the quality of the land has become inferior due to regular loss of fertility and irregular usage. Human activities have also contributed towards land degradation, such as :

a. Deforestation i.e., cutting down of forests.

b. Overgrazing.

c. Mining i.e., extraction of valuable minerals from

the soil.

d. Mineral processing like grinding of limestone.

e. Faulty methods of cultivation and over-irrigation.

What is resource planning? Why is resource planning essential? Explain it with three reasons

Ans : Resource planning is a procedure of proper utilisation of resources. Resource planning is

important because :

a. Resources in India are not evenly distributed. Some parts of the county are rich in one resource but deficient in other important resources which are essential. For example, Rajasthan is rich in solar and wind energy but lacks water resource. Jharkhand is rich in minerals and coal deposits but lack in industrialisation. This is the reason why resource planning is essential. An effectiveresource planning will help in effective use of the resources available in the environment.

b. Secondly, most of the resources present in our environment are limited. Therefore, if these resources are not preserved or not used rationally we will be in great trouble. For example : Petrolis a limited resource and it cannot be renewed. Exhaustion of petrol will create huge chaos in the country as we are extensively dependent on the Petrol.

c. Thirdly, resource planning is important because it minimises the wastage or over utilisation of resources. The very first step of resource planning is to make a list of resources available in the environment. This helps us to assess which resources should be used and how much it should be used to prevent over utilisation and minimise wastage
