NCERT Chapter Summary: Security in the Contemporary World

We hear that an issue is a security issue and that it is vital for the well-being of the country. The implication is that it is too important or secret to be debated and discussed openly.

NCERT Chapter Summary: Contemporary South Asia

When India and Pakistan joined the club of nuclear powers, this region suddenly became the focus of global attention. The focus was, of course, on the various kinds of conflict in this region: there are pending border and water sharing disputes between the states of the region. Besides, there are conflicts arising out of insurgency, ethnic strife and resource sharing.

NCERT Chapter Summary: Globalisation

In this final chapter of the book we look at globalisation, something that has been referred to in many chapters of this book and textbooks of many other subjects. We begin by analysing the concept of globalisation and then examine its causes.

NCERT Chapter Summary: The End of Bipolarity

The Berlin Wall, which had been built at the height of the Cold War and was its greatest symbol, was toppled by the people in 1989. This dramatic event was followed by an equally dramatic and historic chain of events that led to the collapse of the ‘second world’ and the end of the Cold War.

NCERT Chapter Summary: Structure and Physiography

Do you know that our earth also has a history. The earth and its landforms that we see today have evolved over a very long time. Current estimation shows that the earth is approximately 460 million years old.

NCERT Chapter Summary: Climate (Class 11)

The monsoon regime emphasises the unity of India with the rest of southeast Asian region. This view of broad unity of the monsoon type of climate should not, however, lead one to ignore its regional variations which differentiate the weather and climate of different regions of India.

NCERT Chapter Summary: Natural Vegetation

Natural vegetation refers to a plant community that has been left undisturbed over a long time, so as to allow its individual species to adjust themselves to climate and soil conditions as fully as possible. India is a land of great variety of natural vegetation.

NCERT Chapter Summary: Landforms and their Evolution

After weathering processes have had their actions on the earth materials making up the surface of the earth, the geomorphic agents like running water, ground water, wind, glaciers, waves perform erosion. It is already known to you that erosion causes changes on the surface of the earth. Deposition follows erosion and because of deposition too, changes occur on the surface of the earth.

NCERT Chapter Summary: Composition and Structure of Atmosphere

The atmosphere is composed of gases, water vapour and dust particles. The proportion of gases changes in the higher layers of the atmosphere in such a way that oxygen will be almost in negligible quantity at the height of 120 km. Similarly, carbon dioxide and water vapour are found only up to 90 km from the surface of the earth.

NCERT Chapter Summary: Atmospheric Circulation and Weather Systems

Air expands when heated and gets compressed when cooled. This results in variations in the atmospheric pressure. The result is that it causes the movement of air from high pressure to low pressure, setting the air in motion. You already know that air in horizontal motion is wind.

NCERT Chapter Summary: Movements of Ocean Water

The ocean water is dynamic. Its physical characteristics like temperature, salinity, density and the external forces like of the sun, moon and the winds influence the movement of ocean water. The horizontal and vertical motions are common in ocean water bodies. The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides.

NCERT Chapter Summary: Interior of the Earth

What do you imagine about the nature of the earth? Do you imagine it to be a solid ball like cricket ball or a hollow ball with a thick cover of rocks i.e. lithosphere? Have you ever seen photographs or images of a volcanic eruption on the television screen?

NCERT Chapter Summary: Distribution of Oceans and Continents

You know that continents cover 29 per cent of the surface of the earth and the remainder is under oceanic waters. The positions of the continents and the ocean bodies, as we see them in the map, have not been the same in the past.

NCERT Chapter Summary: Land Resources and Agriculture

Land-use records are maintained by land revenue department. The land use categories add up to reporting area, which is somewhat different from the geographical area. The Survey of India is responsible for measuring geographical area of administrative units in India. Have you ever used a map prepared by Survey of India?

NCERT Chapter Summary: Water Resources (Class 12)

India accounts for about 2.45 per cent of the world’s surface area, 4 per cent of the world’s water resources and about 16 per cent of the world’s population. The total water available from precipitation in the country in a year is about 4,000 cubic km.

NCERT Chapter Summary: Mineral and Energy Resources

Metallic minerals are the sources of metals. Iron ore, copper, gold produce metal and are included in this category. Metallic minerals are further divided into ferrous and non-ferrous metallic minerals.

Governance at Union Level

The Constitution of India has made alternate provision for the structure and functioning of all the three branches of the government i.e. executive, legislature and judiciary.

Political Parties and Pressure Groups

A political party is an organised group of citizens who have similar political views and who by acting as a unit try to control the government to translate their policies into practice.

People's Participation in Democratic Process

In a Democracy, people's participation is very important. People, participate to elect their representatives by voting in elections. Discussing the working of the government, public debates, newspaper’s editorials, protest demonstrations, public meetings working for a political party and standing as a candidate are all examples of people's participation.

Challenges to Indian Democracy

India is called the largest democracy in the world. It is democratic because elections take place at regular intervals at different levels.

Biodiversity in India

The diversity of plants and animal provide us food, fuel, medicine, shelter and other essentials without which we cannot live. These species have evolved over thousands of years. This rich diversity is being lost at an alarming rate due to human activities.

Agriculture in India

India is said to be the land of farmers and these farmers are mostly living in the rural India. They are practising farming and are helping the country. Hence, the agriculture in the country is very important.
