Soil and Forest

Soil 

Soil is the crust part of the earth. It is mainly the mixture of rock particles and humus.

• land and soil comprise the weathered layer of the earth’s crust with living organisms and products of their decay.
• Soil is a natural resource, which is required for production of food, industrial raw materials as well as for generation of energy resources. 
•  Soil is often called the "living skin" of the earth.  
• In rural areas, it's easily visible, but in large cities, it's hidden beneath buildings and roads. 
• Two important ways that people use soil are for agriculture and the support of buildings and roads. 
• Soil is a mixture of rock particles and organic matter, such as animal manure, leaves and other plant waste 
• Agriculture Plant growth is a primary use of soil.  
•  Its pH is a major factor in how effective soil is for growing plants, the desired range in between 6.0 to 6.5. 
•  Nation’s economy is inseparably linked with the fertility and abundance of the soil resources.   
•  It supports the growth of plants by holding the roots firmly and supplying water and nutrients.  
• It is the home for many organisms.  
•  Soil is essential for agriculture. Agriculture provides food, clothing and shelter for all.  
• Soil is thus an inseparable part of our life.

 

 

 

 Forest

• It is a natural ecosystem having trees of many ages and species.

• Forest occupy 22.74 percent of the land area in India.

• Wood is used as fuel.
  

• As a natural resources forest supply wood and many other products such as fibers,bamboos,gums,medicines,honey etc.

• Forests are an extremely important natural resource that can potentially be sustainably harvested and managed to yield a diversity of commodities of economic importance.

• Many other plant products can also be collected from forests, such as fruits, nuts, mushrooms, and latex for manufacturing rubber. In addition, many species of animals are hunted in forests, for recreation or for subsistence.

• Forests provide additional goods and services that are important to both human welfare and to ecological integrity, including the control of erosion and water flows, and the cleansing of air and water of pollutants. 

• Plants clean the air, cool it on hot days, conserve heat at night, and act as excellent sound Absorbers.

•  Evergreen forests grow in the high rainfall areas of the Western Ghats, North –eastern India and  the Andaman and Nicobar Islands. These forests grow in areas where the monsoon period lasts for several months.

• Dead plants decompose to form humus, organic matter that holds the water and provides nutrients to the soil.

 

 

Air

Air

•    air is another most precious natural resources on the earth. 
•    it is all around us and freely available. 
•    without air , life would have been impossible on earth. 
•    we are surrounded by a mixture of gases which we breathe, Its known as Air.  
•  we can not see, smell or taste air, but we can feel it moving when wind is blows. 
•    air in motion is known as wind.
     Air around us protects us from harmful rays of the sun. 
•   Sound waves travels through air enabling us to hear. 
•     Sound can not  travel in vacuum.

Meaning and type of Natural resource

                                                           Natural Resources 

 What is Natural resources?

Natural resource is anything that people can use which comes from nature.


A natural resources is thus, anything required by an organization or a group of organization.
In the context of human beings, any part of our natural environment , like land, metals, water and air, forests, wildlife, fish, etc. ,that man can utilize for his welfare may be regarded as natural resources.

Types of Natural Resources

• Renewable
• Non renewable 

Renewable resources are those resources that can be regenerated such as air water forest wildlife etc.
Non renewable resources are those resources that can not be regenerated such as minerals, soil, fuel and similar things.
  
 What is the difference between renewable and non renewable resources?

              Renewable resources                                                 Non renewable resources

  1. The resources that can be renewed by         1.  The resources that are present in fixed  

       Reproduction is called renewable                      quantity is Called non renewable resources

       resources

  2. Renewable resources are inexhaustible       2. Non renewable resources are exhaustible

  3. Renewable resources are not affected by    3. Non renewable resources are affected  by

      human beings activities                                       human activities

  4. All biotic resources are renewable                4.  Some  abiotic component are non 

      resources                                                               renewable resources

  5. For example :- Air, water, forest                    5.  For example :-  fossil fuel, minerals, coal,

      wildlife, solar power etc                                        metal etc

 In another word we can say that 

1. The Renewable resources are able to reproduce or replace themselves where as Non renewable resources is used , it is gone- one must find a substitute or do without it.
2. The Renewable resources are interrelated if a forest cut or burned, not only the timber affected but also the soil is damaged and the water relationships are disturbed. stream flow and underground water supply are also disturbed, It is not the same with Non renewable resources, they are only interrelated through agency of man removing. the coal from an area will not influence the amount of other mineral in the underground deposits.
3. For the Renewable resources , management is based on the principal of a sustained yield.with proper management , tree can be cut every year and yet there will be the tree in future,for the Non renewable resources good management is wise used of resources with avoidance of waste.
