India – Size and Location

India is a vast country. We are said to be country with diverse culture, traditions and physical features. The chapter is about size of India in terms of area and where it is located in world. The main land extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E. The land mass of India has an area of 3.28 million square km. The tropic of cancer passes through India.

Physical Features of India

While going from North to South, or east to west across India, great physical variation can be observed. There are mountain ranges like Himalayas, Plains, Plateaus and Coastal areas. The physical features of India can be grouped under the physiographic divisions- The Himalayan Mountains, The Northern Plains, The Peninsular Plateau, The Indian Desert, The Coastal Plains, and The Islands. The Himalayan Mountains are considered as protector of India and provides drainage to northern plain which feeds India by its agricultural production. By going through the chapter, you can learn how every physiological division play important role in development of nation.

Drainage

The term drainage describes the river system of an area. The third chapter of NCERT textbook of Geography for class 9 is about rivers. Rivers have been the basis of many civilisations. Most of the populations have been settled across rivers. For northern plains, having most of the agricultural area, river Ganga have been the major source of irrigation. The chapter is about river system of India. In India we have basically two types of rivers based on their origin- Himalayan rivers and Peninsular rivers.

Some important peninsular rivers are Narmada, Godaveri, Kaveri, etc. After rivers, lakes has been discussed in the chapter. Rivers play important role in development of economy. Rivers for important for irrigation, navigation, hydro-power generation. At last, in chapter, the concern of river pollution has been mentioned.

Climate

Climate of an place decides the nature of habitation and vegetation of an place. Defining climate, it is the average of weather condition of an area. The elements of weather and climate are the same, i.e. temperature, atmospheric pressure, wind, humidity and precipitation. Basically, these things are factors which decide climate of an area. The climate of India is described as the ‘monsoon’ type. The variation of India is not only in its culture but also in its climate. In winter, the temperature in Kashmir can be low like -20° and in winter and in same time temperature somewhere in Kerela can be 22°. In summer, Kashmir will have 15° but in Rajasthan it can be 50°. We will be discussing about all these and factors responsible for it. We will discuss about climate controllers like pressure, latitude, altitude, and oceans. Monsoon and its mechanism has been discussed in the chapter which is very interesting topic. So, lot to learn in the chapter and NCERT solutions provided here will make it easy for you to learn.

Natural Vegetation and Wildlife

Natural Vegetation describes the plant species that naturally grow in an area according to its climatic and other conditions of an area. In India 47,000 plant species India occupies tenth place in the world and fourth in Asia in plant diversity. Vegetation depends upon climatic factors such as temperature and precipitation as well as upon factors like land and soil. Tropical Evergreen Forests, Tropical Deciduous Forests, Tropical Thorn Forests and Scrubs, Montane Forests and Mangrove Forests are different types of vegetation cover discussed in the fifth chapter of NCERT Geography textbook of class 9.
India is not only rich in its vegetation but also in wild life. India has approximately 90,000 animal species. We have about 2,000 species of birds in our Country. They constitute 13% of the world’s total. India is the only country in the world that has both tigers and lions. There are other interesting facts about wildlife of India discussed in the chapter.

Population

We discussed about climate, vegetation, drainage etc., till now. But, the human resource take the best out of these resources. The people are important to develop the economy and the society. The people make and use resources and are themselves resources with varying quality. The chapter is about population, its distribution and quality. India as we know is second most populous country in world.
The population density of India in the year 2011 was 382 persons per sq km. Densities vary from 1,102 persons per sq km in Bihar to only 17 persons per sq km in Arunachal Pradesh.
