Earth’s Layers – Earth’s Composition

by

 

The Crust of Earth

It is the outermost and the thinnest layer of the earth’s surface, about 8 to 40 km thick. The crust varies greatly in thickness and composition – as small as 5 km thick in some places beneath the oceans, while under some mountain ranges it extends up to 70 km in depth.

The crust is made up of two layers­ an upper lighter layer called the Sial (Silicate + Aluminium) and a lower density layer called Sima (Silicate + Magnesium).The average density of this layer is 3 gm/cc.

The Mantle of Earth

This layer extends up to a depth of 2900 km.

Mantle is made up of 2 parts: Upper Mantle or Asthenosphere (up to about 500 km) and Lower Mantle. Asthenosphere is in a semi­molten plastic state, and it is thought that this enables the lithosphere to move about it. Within the asthenosphere, the velocity of seismic waves is considerably reduced (Called ‘Low Velocity

The line of separation between the mantle and the crust is known as Mohoviricic Discontinuity.

 

The Core of Earth

Beyond a depth of 2900 km lies the core of the earth.The outer core is 2100 km thick and is in molten form due to excessive heat out there. Inner core is 1370 km thick and is in plasticform due to the combined factors of excessive heat and pressure. It is made up of iron and nickel (Nife) and is responsible for earth’s magnetism. This layer has the maximum specific gravity.The temperatures in the earth’s core lie between 2200°c and 2750°c. The line of separation between the mantle and the core is called Gutenberg­Wiechert Discontinuity.

Preamble and its significance

by

The Constitution of India begins with a Preamble which describes the nature of the Indian State and the objectives it is committed to secure. K.M. Munshi describes the Preamble as the political horoscope of the constitution. Thakur Dass Bhargawa says Preamble is the most precious part and the soul of the constitution.

The Preamble reads:

We, the People of India having solemnly resolved to constitute India into a Sovereign, Socialist, Secular, Democratic, Republic and to secure to all its citizens;

Justice, social, economic, political;

Liberty of thought, expression, belief, faith and worship;

Equality of status and opportunity; and to promote among them all;

Fraternity, assuring the dignity of the individual and the unity and integrity of the nation ;

In our Constituent Assembly this, twenty sixth day of November 1949 do hereby Adopt, Enact and Give to ourselves this Constitution.

The words ‘Socialist ‘Secular” and ‘Integrity were initially not there in the Preamble. These were added by the 42nd Amendment (1976) of the Constitution.

Preamble: Features:

I. The Source of Authority:

Popular Sovereignty:

The Preamble categorically accepts the principle of Popular Sovereignty. It begins with the words: ‘We the people of India’. These words testify to the fact that the people of India are’ the ultimate source of all authority. The Government derives its power from them.

II. Nature of State:

The Preamble describes five cardinal features of the Indian state:

(1) India is a Sovereign State:

The Preamble proclaims that India is a sovereign state. Such a proclamation denotes the end of rule over India. It testifies to the fact that India is no longer a dependency or colony or possession of British Crown. As a sovereign independent state, India is free both internally and externally to take her own decisions and implement these for her people and territories.

(2) India is a Socialist State:

In 1976, the Preamble was amended to include the word ‘Socialism’. It is now regarded as a prime feature of the State. It reflects the fact that India is committed to secure social, economic and political justice for all its people. India stands for ending all forms of exploitation as well as for securing equitable distribution of income, resources and wealth. This has to be secured by peaceful, constitutional and democratic means. The term ‘India is a Socialist state’ really means, ‘India is a democratic socialist state.’

(3) India is a Secular State:

By the 42nd Amendment, the term ‘Secular’ was incorporated in the Preamble. Its inclusion simply made the secular nature of the Indian Constitution more explicit. As a state India gives special status to no religion. There is no such thing as a state religion of India. India guarantees equal freedom to all religions. All religions enjoy equality of status and respect.

(4) India is a Democratic State:

The Preamble declares India to be a Democratic State. The Constitution of India provides for a democratic system. The authority of the government rests upon the sovereignty of the people. The people enjoy equal political rights. The people freely participate in the democratic process of self rule.

They elect their government. For all its acts, the government is responsible before the people. The people can change their government through elections. The government enjoys limited powers. It always acts under the Constitution which represents the supreme will of the people.

(5) India is a Republic:

The Preamble declares India to be a Republic. Negatively, this means that India is not ruled by a monarch or a nominated head of state. Positively, it means that India has an elected head of state who wields power for a fixed term. President of India is the elected sovereign head of the state. He holds a tenure of 5 years. Any Indian citizen can get elected as the President of India.

III. Four Objectives of the Indian State:

The Preamble lists four cardinal objectives which are to be “secured by the state for all its citizens”.

These are:

(1) Justice:

India seeks to secure social, economic and political justice for its people.

(i) Social Justice:

Social Justice means the absence of socially privileged classes in the society and no discrimination against any citizen on grounds of caste, creed, colour, religion, sex or place of birth. India stands for eliminating all forms of exploitations from the society.

(ii) Economic Justice:

Economic Justice means no discrimination between man and man on the basis of income, wealth and economic status. It stands for equitable distribution of wealth, economic equality, end of monopolistic control over means of production and distribution, decentralisation of economic resources, and securing of adequate opportunities to all for earning their livelihoods.

(iii) Political Justice:

Political Justice means equal, free and fair opportunities to the people for participation in the political process. It stands for the grant of equal political rights to all the people without any discrimination. The Constitution of India provides for a liberal democracy in which all the people have the right and freedom to participate.

(2) Liberty:

The Preamble declares liberty to be the second cardinal objective to be secured. It includes liberty of thought, expression, belief, faith and worship. The grant of Fundamental Rights (Part III) including the right to freedom is designed to secure this objective. Liberty of faith and worship is designed to strengthen the spirit of secularism.

(3) Equality:

The Preamble declares Equality as the third objective of the Constitution. Equality means two basic things:

(i) Equality of status i.e. natural equality of all persons as equal and free citizens of India enjoying equality before law.

(ii) Equality of opportunity i.e. adequate opportunities for all to develop. For securing the equality of status and opportunity, the Constitution of India grants and guarantees the fundamental Right to Equality.

(4) Fraternity:

Promotion of Fraternity among the people is the fourth objective is to promote Fraternity among all the people. Fraternity means the inculcation of a strong feeling of spiritual and psychological unity among the people. It is designed to secure dignity of the individual and unity and integrity of the nation.

IV. Date of Adoption and Enactment:

In its final paragraph, the Preamble specifies the important historical fact that the Constitution was adopted on 26 November, 1949. It was on this day that the Constitution received the signatures of the President of the Constituent Assembly and was declared passed.

V. Self-made Constitution:

The Constitution of India is an adopted, enacted and self-made constitution. It was adopted and enacted by the Constituent Assembly acting as the elected representative body of the people of India. The Preamble states the philosophical foundations of the Constitution India and enumerates its objectives.

It constitutes a Key for the interpretation of the Constitution. It is a part of the Basic Structure of the Constitution. Through, it’s Preamble, the Constitution a commits itself to Democracy, Republicanism, Socialism, Secularism, Liberalism and Welfare State. The Preamble states the objectives which the Constitution is committed to secure for all the people of India.

Wavell Plan & Shimla Conference-

by

In May 1945, Lord Wavell, the Viceroy of India, went to London and discussed his ideas about the future of India with the British administration. The talks resulted in the formulation of a plan of action that was made public in June 1945. The plan is known as Wavell Plan.

The Plan suggested reconstitution of the Viceroy’s Executive Council in which the Viceroy was to select persons nominated by the political parties. Different communities were also to get their due share in the Council and parity was reserved for Cast-Hindus and Muslims. While declaring the plan, the Secretary of State for Indian Affairs made it clear that the British Government wanted to listen to the ideas of all major Indian communities. Yet he said that it was only possible if the leadership of the leading Indian political parties agreed with the suggestions of the British Government.

To discuss these proposals with the leadership of major Indian parties, Wavell called for a conference at Simla on June 25, 1945. Leaders of both the Congress and the Muslim League attended the conference, which is known as the Simla Conference. However, differences arose between the leadership of the two parties on the issue of representation of the Muslim community. The Muslim League claimed that it was the only representative party of the Muslims in India and thus all the Muslim representatives in the Viceroy’s Executive Council should be the nominees of the party. Congress, which had sent Maulana Azad as the leader of their delegation, tried to prove that their party represented all the communities living in India and thus should be allowed to nominate Muslim representative as well. Congress also opposed the idea of parity between the Cast-Hindus and the Muslims. All this resulted in a deadlock. Finally, Wavell announced the failure of his efforts on July 14. Thus the Simla Conference couldn’t provide any hope of proceeding further.

They enjoy the same status and receive salary and perks as available to Judges of the Supreme Court of India. The Chief Election Commissioner cannot be removed from office, except on the grounds and in the manner on which the Supreme Court judges can be removed. However, since the other Election Commissioners and the Regional Election Commissioners work under the Chief Commissioner, they may be removed by the President on his recommendations.

The Commission conducts elections in accordance with the constitutional provisions, supplemented by laws made by Parliament. The major laws include Representation of the People Act, 1950, which mainly deals with the preparation and revision of electoral rolls, the Representation of the People Act, 1951 which deals, in detail, with all aspects of conduct of elections and post election disputes.

    • Meetings with NGOs and citizens’ forums and appeal to political parties and candidates for self-restraint
  • Punitive
    • CEOs of the state would identify those constituencies which were prone to high expenditure and corrupt practices. Large number of assistant expenditure observers and more number of flying squads and surveillance teams would be posted in these constituencies

Rashtrakutas

by

Rashtrakutas

The Rashtrakutas called themselves descendants of one named Satyaki. But there is difference of opinion about their origin among the historians. According to some they were originally of Dravidian peasant extraction. From some of the inscriptions of the Chalukya kings it is known that the Rashtrakutas were feudatories of the Chalukyas. Perhaps their original home was Karnataka and their mother tongue was Kanarese.

Important rulers of rashtrakuta dynasty

Krishna I

Dantidurga was succeeded by his uncle Krishna I. He conquered the territories that were still under the Chalukyas and thereby competed conquest of the Chalukya territories. He also occupied Konkan. It is not known for certain the name of the country over which Rahappa used to rule. Vishnuvardhana of Vengi and the Ganga king of Mysore were defeated at the hands of the Rashtrakuta King Krishna I.  The Kailash Temple at Ellora was built by the Rashtrakuta King Krishna I. He was a great patron of art and architecture.

Govinda II

Krishnaraja’s eventful career came to an end within a very short time and he was succeeded by his son Govindaraj who ruled for some time as Govinda II. His worthlessness as a ruler and his lack of interest in administration led to his deposition by his brother Dhruva who ascended the throne himself.

Dhruva

Dhruva was by far the best ruler of the Rashtrakuta dynasty. He ruled for a short span of time but within this short time he entered into struggle with the Gurjara-Pratihara King Vatsyaraja and defeated him signally. He also like wise defeated the Pallavas of Kanchi and the Pala King Dharmapala of Bengal.

 

 

Govinda III

Dhruva was succeeded by Govinda III his son and with almost equal vigor as of his father. He succeeded in keeping the Gurjara power sufficiently under control. He defeated the great Gurjara King Nagabhatta II. It is said that the Pala King Dharmapala and his protégé Charayudh sought the help of Govinda III. Govinda III made the Rashtrakutas dynasty one of the most powerful dynasties of contemporary India. His kingdom spread up to the Vindhyas and Malava in the north and the river Tungabhadra to the south.

Amoghavarsha I

The greatest king of the Rashtrakuta dynasty was Amoghavarsha I. As a warrior he was, however, no match with his father Govinda III, but he succeeded in defeating the East-Chalukya kings.  Amoghavarsha I set up a new capital at Manyakheta (now Malkhed in Karnataka State) and during his reign Broach became the best port of his kingdom.  Amoghavarsha I was a great patron of education and literature. From the evidence of the Jaina works it is known that Amoghavarsha was converted into Jainism by Jinasena, a Jaina monk.

Amoghavarsha spent the accumulated wealth of his predecessors to beautify his kingdom.  Suleman, an Arab merchant, in his account called Amoghavarsha I as one of the four greatest kings of the world, the other three being the Caliph of Bagdad, the king of Constantinople and the emperor of China.

Krishna II

Amoghavarsha ruled for 63 years and he was succeeded by his son Krishna II who in his turn was succeeded by Indra III.

Indra III

Indra III was a powerful king. He defeated and deposed Mahipala.  The Rashtrakuta Kings Amoghavarsha II, Govinda IV and Amoghavarsha III were weak kings.

 

 

Krishna III

The last powerful and efficient king of the Rashtrakutas was Krishna III. He had a prolonged struggle with Mahipala, the Gurjara king. He also succeeded in conquering Tanjore and Kanchi. In the middle of the tenth century for a time he succeeded in defeating the Tamil kings of Chola kingdom. But towards the end of the same century the Rashtrakuta King Kaka was defeated and deposed by Taila or Tailapa, the Chalukya king of Kalyani. With Kaka’s defeat the Rashtrakuta power came to an end.

Architecture of rashtrakutas

The Rashtrakutas contributed much to the architectural heritage of the Deccan. Art historian Adam Hardy categorizes their building activity into three schools: Ellora, around Badami, Aihole and Pattadakal, and at Sirval near Gulbarga. The Rashtrakuta contributions to art and architecture are reflected in the splendid rock-cut cave temples at Ellora and Elephanta, areas also occupied by Jain monks, located in present-day Maharashtra. The Ellora site was originally part of a complex of 34 Buddhist caves probably created in the first half of the 6th century whose structural details show Pandyan influence. Cave temples occupied by Hindus are from later periods.

The Rashtrakutas renovated these Buddhist caves and re-dedicated the rock-cut shrines. Amoghavarsha I espoused Jainism and there are five Jain cave temples at Ellora ascribed to his period.The most extensive and sumptuous of the Rashtrakuta works at Ellora is their creation of the monolithic Kailasanath Temple, a splendid achievement confirming the “Balhara” status as “one among the four principal Kings of the world”. The walls of the temple have marvellous sculptures from Hindu mythology including Ravana, Shiva and Parvathi while the ceilings have paintings.

Arunachal Pradesh Scheduled Tribes

by

 

The Nishi:

The Nishi occupied the hilly terrains of the Lower Subansiri, Papum Pare and East Kameng Districts of present Arunachal Pradesh. Haimendrof, says these tribesmen were earlier known as Dafla. But they now that want they should be called as Nishi. The Nishis do not have script of their language. The stories of their origin and migration are vague and unclear. Such stories are told by their ancestors from generation to generation in course of their migration.

The Daflas believed that their ancestors lived in a place called Supung which was far away in the east. First they came to a place which they remembered as Narba and, later passing through Begi, Bolo and Yalang, they crossed Shinit or Subansiri river and finally went over to another Kumme or Kamla river. From there they gradually spread over the tract lying between the Kamla and Khru rivers and pushed far up to the Palin and the Panior hills.

Hill Miris:

The Hill Miris occupied the region both sides of the Kamla river east of its confluence with the Khru and as far as its junction with the Subansiri. West of the Dirjemo and to the north of the Sissi sub-division of the Lakhimpur district, the Ghy- Ghasi Miris, the Sarak Miris north of Bordoloni, and on both banks of the hill course of the Subansiri river. The Panibotia Miris derived the name as they journeyed to the plains through the rivers on the canoes while Tarabotia Miri derived their name for traveling through land .

Hill Miris were akin to the Nishis(Daflas) both racially and culturally.  also referred to the settlement patterns between the Hill Miris and Nishis (Daflas) on the basis of their inhabitation in the mountain ridges and says that feudes between a Hill Miri village and a Nishi (Dafla) village often took place.

Apa Tanis:

The Apa Tanis are one of the few self sufficient tribes of Arunachal Pradesh, occupying a part of the Subansiri district. The highland, watered by river Kali which ultimately falls into the Panir, is inhabited by these people. The ApaTanis are not only good cultivators but expert traders and meet all their necessities in exchange of paddy which is always in excess of their requirements. Their interest has got additional momentum because of the establishment of the Headquarters of the district at Ziro in the ApaTani plateau.Till the last part of nineteenth century the existence of the Apa Tanis tribe were not known to the plain peoples.

Apa Tanis believe that their community decended from the mythical ancestor , Abo Tani, who came from a country north or north-east of Arunachal Pradesh, situated near two rivers known as Supupad Pudpumi.

Tagin:

Tagins are spread over an area covering roughly about 15000 square kms.It is bounded by China (Tibet) in the north, West Siang District of Arunachal Pradesh in the East, Lower Subansiri and Kurung Kumey districts in the West, the confluence of Sinik (Subansiri) and Sigen rivers in the South west, and Sinyum river in South-East.

The Tagins are believed to have migrated from the Penzi, a village in Tibet in Tadedage region.  Tagins moved from place to place in search of cultivable land. Like the Boris, Bokars and Ramos they moved from north of Mechuka region in West Siang District. They said to have settled in two places which is located at present in Bori region. They continued their migration and in course of time changed the direction and came uphill by the bank of the river Subansiri till they reached the final place where their ancestor decided to settle down.

Adis:

The Adis occupy the east, West and upper Siang districts of the state. Previously they were knownas ‘Abor’ meaning ‘unruly’ or ‘disobedient’. They were very much independent in their nature. The astonishing change that has come over the Abors in recent years, transforming them into a friendly, co-operative, progressive community has made the use of the old name inappropriate. They themselves have suggested, the name ‘Adi’ in place of ‘Abor’.The word ‘Adi’ meant ‘hillmen’. The government then accepted this proposition.

The word ‘Adi’ covers a large number of tribal groups. They are united, although they speak in different dialects. But fundamentally it is same everywhere including their culture and temperament. The Adis fall into two main groups. One group includes the

  • Minyongs,
  • Padams,
  • Pasis,
  • Panggis,
  • Shimongs,
  • Boris,
  • Ashings and
  • Tengams

While the other is the Gallong groups consisting of

  • Ramos,
  • Bokars and
  • Pailibos of the far north.

The Minyongs and the Gallong who were previously referred to and classified as Minyong Abor and Gallong Abor now known as Adi Minyong and Adi Gallong. The word Adi has now been prefixed to the Minyong and Gallong in the list of schedule tribes.
