Class 3 Social Science Chapter- 5 Our Beautiful Country Content-1 Landforms of India CLASS 3 SOCIAL SCIENCE CHAPTER- 5 OUR BEAUTIFUL COUNTRY CONTENT-1 LANDFORMS OF INDIA LANDFORMS OF INDIA HILLS AND PLAINS PLATEAUS DESERTS ISLANDS MOUNTAINS MAJOR LANDFORMS AND RIVERS OF INDIA HILLS AND MOUNTAINS • A high land with a round top is called a hill . The Vindhya Ranges in central India and the Nilgiri Hills in south India are examples of hills. • Very high hills with sharp tops (peaks) are called mountains . The Himalayan Mountain Ranges in the north is a example of mountains. • The Himalayan Mountain Ranges lie in the north. There are many peaks in these mountains. In mountain regions, it is cold throughout the year. • Mount Everest, on the Nepal-China border, is the highest peak in the Himalayan mountain ranges as well as in the world. Many rivers such as the Ganga, Yamuna, Satluj and Brahmaputra originate in these mountains and flow down to the plains. These rivers are formed by the melting snow. THE HIMALAYAS ARE THE HIGHEST MOUNTAIN RANGE IN THE WORLD PLAINS • Flat and level land is called a plain . To the south of Himalayas lie the Great Plains of India. In the plains, summers are hot and winters are cold. Rivers such as the Ganga and the Yamuna flow through these plains. These rivers have made the sofiel rtile . As a result, many crops are grown here. • There is a narrow strip of flat land along the eastern and the western coasts of India. It is known as the Eastern Coastal Plain and the Western Coastal Plain. These plains meet at Kanniyakumari. Rivers such as the Narmada, Tapi, Mahanadi, Godavari, Krishna and Kaveri flow through these plains and fall into the sea. The coastal areas are neither very hot nor very cold. THE GREAT PLAINS ARE ALSO KNOWN AS THE FOOD BASKET OF INDIA PLATEAUS • A high land with steep sides and a flat top is called a plateau . The southern part of India is a plateau. • The southern plateau is called the Deccan Plateau. It covers the largest area of our country. The region is surrounded by hill ranges on three sides. It has an uneven surface. The land is hard and rocky. It is less fertile than the plains. • There are many rivers in the Deccan Plateau. They depend on the rain for water. Some parts of the plateau ae covered with thick forests. • The southern part of India is surrounded by water bodies on three sides. This type of land is called a peninsula. THE SOUTHERN PLATEAU IS LOCATED BETWEEN THE EASTERN AND WESTERN COASTAL PLAINS DESERTS • A large area of land covered with sand is called a desert . In the north-western part of India lies the Indian Desert, also called the Thar Desert. It covers a large part of Rajasthan. This area is hot and dry. It gets very little rainfall. Very few plants and trees grow here. • The largest desert in the world is the Sahara. It lies in the northern Africa. The Sahara is one of theh ottest regions in the world. CAMELS ARE THE MAIN MEANS OF TRRANSPORT INDICATES THAR DESERT IN DESERTS ISLANDS • A piece of land surrounded by water on all sides is called an island . There are two groups of islands in our country. The Andaman and Nicobar Islands lie on the eastern side, in the Bay of Bengal . The Lakshadweep Islands lie on the western side, in the Arabian Sea .

    UNIT – I PHYSIOGRAPHIC DIVISIONS OF INDIA Geological Structure 1. THE ARCHAEAN FORMATIONS (PRE-CAMBRIAN) The Archaean Era is also known as the Precambrian Period. The division of geologic time scale from the formation of the Earth (about 4.6 billion years ago) to the beginning of the Cambrian Period of the Paleozoic Era (about 570 million years ago}. The Precambrian time constitutes about 86.7% of the Earth's history. The term 'Archaean', introduced by J.D. Dana in 1782, refers to the oldest rocks of the Earth's crust. The oldest known rocks of the Earth, the evolutionary atmosphere, the first chemosynthesis, the first photosynthesis, the life-supporting atmosphere and the Earth's modem atmosphere, were developed during the Precambrian Era (Archaean and Protozoic). Rocks of the Archaean System are devoid of any form of life. The Archaean rocks are all azoic or non fossiliferous. They are thoroughly crystalline, extremely contorted and faulted, and practically devoid of any sediment. They are largely intruded by plutonic intrusions and generally have a well-defined foliated structure. These rocks are known as the basement complex or fundamental gneisses. Cover two-thirds of Peninsular India. In the Peninsular region, the Archaean rocks are known to be of three well-defined types: a) The Bengal Gneiss occurs in the Eastern Ghats, Orissa (known as Khodoliles after Khond tribes in Koraput and Bolangir districts), stretching over Manbhum and Hazaribagh districts of Jharkhand, Nellore district of Andhra Pradesh and Salem district of Tamil Nadu. Occur in the Son Valley, Meghalaya Plateau and Mikir HiUs. Thinly foliated.

Bedrock landforms and bedrock rivers are more common. The diversity in topography, drainage and landforms visible today has developed during the nearly 9000 km long northward journey of the Indian Plate since the breakup of the Gondwanaland. Some of the distinctive topographic and drainage network characteristics of this ancient landmass are described in this paper. An attempt has also been made to tentatively reconstruct the ancestry of the main-stem rivers on the basis of available geological and geomorphic data.Multiple lines of evidence suggest that many of the river systems of the Peninsula consist of segments of different ages, and the complete integration of the older and younger drainage has taken place during the Cenozoic. Recently acquired geochronological data strongly suggest that climate rather than tectonics is primarily responsible for the modern-day relief of this ancient landmass.

Constructive approach, Spiral Approach and Integrated approach The learner is encouraged to think, engage in activities, master skills and competencies. The materials presented in these books are integrated with values. The new books are not examination oriented in their nature. On the other hand they help the learner in the all round development of his/her personality, thus help him/her become a healthy member of a healthy society and a productive citizen of this great country, India.

By contrast, the have developed over a relatively stable platform, and landforms in the cold arid region are mountainous, and have developed bear strong impressions of several cycles of late at the junction of the quasi-mobile Indian and the Eurasian plates. Quaternary climate change between warm wet and dry This factor, as well as the vast difference in thermal regime of the two cool phases, which dictated the spatiotemporal regions, determines the types of subaerial denudation processes in the two regions, even though both the areas receive ~300 mm or less distribution of the fluvial and aeolian processes and the mean annual precipitation (Krishnan and Thanvi, 1977; Hobley et typical disposition of the landforms.

Thus, while the hot arid region is largely dominated located in the Trans-Himalaya, is mountainous and by wind erosion and/or sheetwash and periodic flooding by ephemeral dominated by glacial, periglacial and fluvial processes, streams, the cold arid region is subjected to glacial, glacio-fluvial with fewer signatures of lacustrine and aeolian processes.

The map cover parts of India, Bhutan, Nepal, Sri Lanka, Bangladesh, Myanmar, and Pakistan and some of the offshore regions. The Extra-Peninsular region includes the Cenozoic Himalayan Orogen in Pakistan, India Nepal, Bhutan and its possible extension into Myanmar. This belt is separated fronm the Peninsular region by the vast late Cenozoic-Pleistocene Indo-Gangetoc-Brahmaputra Basin. The Peninsular India is mostly composed of six Archean-Proterozoic cratonic nuclei with indications of Hadean elements in Singhbhum. Proterozoic mobile belts surround these nuclei; hence the peninsular part might have been a single continent till end of Proterozoic. Deformation and metamorphism gradually decreased in their intensity, when vast Proterozoic sedimentary basins evolved over the Indian cratons and mobile belts unconformably. Paleo-Mesozoic rifts created the coal-bearing Gondwana basins, followed by marine transgressions before the onset of extensive Deccan volcanic eruptions in the western parts of the continent.
