The population density is a measurement of population per unit area. It is mainly beings. Sikkim is the least populated state in India, which actually became part of India in the year 1975. It is a land locked state, which is surrounded by West Bengal state of India and other neighbouring countries like Bhutan, Tibet and Nepal. This state is significant in being one of the most preferred natural travel destinations for the tourists around the world.

Following are the four main reasons why it is sparsely populated: 

1. It really covers very small area.

2. Most of the land is covered with high mountains.

3. The extremely cold climate creates inhabitancy difficult.

4. More number of tourists than available space for residents.

 Apart from Sikkim, other places like Arunachal Pradesh, Lakshadweep, Andaman, Dadra and Nagar Haveli, and Mizoram are some of the least populated states / union territories in India.

Potential resources are the resources which are currently not fully utilised. We do have the technology to extract them but their extraction has not been started yet at a larger level. Reasons can be lack of investment, for e.g., Rajasthan and Gujarat receive plenty of solar energy and have plenty of wind energy, but the use of these resources so far has not been developed properly.

Developed resources are the resources of which the quality as well as the quantity has been surveyed and utilisation has been determined.  On the other hand, the development is said to be based on technology as well as their feasibility. 

Stock is the resources for which presently, we don’t have any technology to extract them. For e.g Water consists of Hydrogen and Oxygen.  Hydrogen is considered as one of the sources of energy but we do not know the technology to extract energy from it.

Reserve resources are those which we are not extracting them at present in spite of technological availability. They are stored to meet the world’s future requirements. 

The word Laterite is derived from Latin word ‘later’ which means ‘brick’. Main reason of laterite soils formation is due to intense leaching. Leaching happens due to high tropical rains and high temperature. As a result of high rainfall, lime and silica are leached away, and soils rich in iron oxide and aluminium compound are left behind. These soils are poor in organic matter, nitrogen, phosphate and calcium, while iron oxide and potash are in excess. These soils are developed on the summits of hills and uplands. In India, they are mostly found in Kerala, Karnataka, Tamil Nadu, Maharashtra, Chhattisgarh and hilly areas of Orissa and Assam. These soils have mainly developed in the higher areas of the peninsular plateau. 

Red laterite soils which is mainly found in Tamil Nadu, Andhra Pradesh and Kerala are more suitable for tree crops like cashewnuts. This soil is widely cut as bricks for use in house construction also. 

Hint: A resource is defined as a physical material that humans value and need such as land, air, and water for their survival. Resources can be characterized as renewable or nonrenewable; 

A renewable resource replenishes itself at the rate it is being used.

While a nonrenewable resource has a limited supply. Wind, timber and solar energy are all examples of renewable resources while coal and natural gas are nonrenewable resources. Anything from air to water to silver are all resources. 

Complete answer:

There are two types of resources which are as follows:

1. Natural resources are materials obtained from the Earth that are used for the sustenance of life and meet people’s needs or we can say that these are the resources that exist without any actions of humankind. Oil, coal, natural gas, metals, stone and sand are some examples of natural resources.

2. Human made resources, or capital resources, are material riches created by humans that can be used to get more wealth. Examples include money, factories, roads, and technology.

Or we can say that human beings change resources into new forms like people use natural resources to make buildings, bridges, machinery and vehicles with the help of technology. Such resources are called human-made resources. 

Man-made resources are mostly renewable. One can re-build a building or fix a broken machine. Also, as humans we have desired skills, intelligence, and knowledge, and use technology to transform a natural resource into usable and valuable things, they themselves become a resource. This is what we know as Human Resources. So in simple words we can say that human resources are the people who add utility to the resources by adding value to it. Manmade resources are the objects or things that are converted into accessible forms after changing their original forms. Example include, electricity is a human-made resource. 

Note:

Examples of man-made resources are- plastic, paper, soda, sheet metal, rubber and brass. 

Examples of natural resources- such as water, crops, sunlight, crude oil, wood and gold. So we can say that humanized resources are the items or substances that do not occur in the natural world and have value to human lives. 

The right to education means that the state should make adequate provision to educate its citizens. Education sharpens the intellect, gives individuals the ability to work and trains them to the art of citizenship. 

Citizenship has been defined “as the contribution of one’s learned judgment to the public good”.

Education is a prerequisite for liberating individual development and making the man fit for the tasks of citizenship. Laski says, “In the long run, power belongs to those who can formulate and grasp ideas.” 

An uneducated individual can neither understand politics nor be vigilant about his or her interests and, therefore, his or her effective participation in state affairs is usually negligible.

Such a citizen must be the slave of others. He will not have the opportunity to rise to the fall size of his personality. “It will go through the life of a stunted being whose impulses have never been ordered by reason in the creative experience.”   

It means the failure of democracy, because the people who are the ultimate masters will not be able to intelligently exercise their right to vote or perform their other civic duties satisfactorily. Thus, the democratic slogan is: “Educate the masters”. Apparently, the right to education is a civil right, but in reality it is a political right that protects it. 

The right to education, however, does not mean the same intellectual training for all citizens. It only means providing that kind of education that should give all citizens an equal chance in this branch of knowledge for which they have an aptitude. Then there should be a mandatory minimum education level below which no one will fall, if it has to conform to the standard of a good citizen.   

Every citizen should have at least as much education as possible to weigh, judge, choose and decide for himself. “We must make him feel that it is a world in which he can, by the use of his mind, shape both the outline and the substance”. 

Force is a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object. It causes objects to accelerate. SI unit is Newton.

Force can bring about following impacts on a body:

1. Change the speed of a moving body

2. Change the direction of the moving body

3. Move an object from rest

4. Change the shape of a body
