(xii) A Tributary and A Distributary A Tributary 1. A river or stream that joins the large river. A Distributary It is a channel formed by the rivers at the mouth to bypass the deposits it has left in the main channel. 2. It is generally found in the upper or the middle course of the river. It is found in the lower course of a river, a little before it joins the sea. 3. As for example Yamuna river is the tributary of the river Ganga. As an example, when Ganga enters the Bay of Bengal forming itself into many distributaries. 4. (xiii) It increases the volume of the water of the main river. It decreases the volume of the main river. An Estuary and A delta An Estuary 1. A Delta It is a narrow deep valley at the mouth of the river where the currents It is a triangular landform which is formed by the deposition of the or the tides are strong or the currents of the river itself are swift. The sediments at the mouth of the river. It is formed by the river. The sediments are automatically removed before they are deposited and river is often very swift at the source and in its upper course. As a so the mouth of the river remains clear of the mud to form an result, it carries large quantities of mud and silt. In the course of time, estuary. the river bed is raised and the currents have to find their new channel. As a result it is divided into branches which together form the delta. (xiv) 1. Indo- Gangetic Plain and The Deccan Plateau Indo- Gangetic Plain The Deccan Plateau It extends from the Punjab plain in the west to Brahmaputra valley in It lies in the south of the Indo-Gangetic Plain. It is triangular in shape. the east. This plain lies to the south of the Himalayas. It bounded on its north by the Vindhyas and the Satpura hills while its eastern and the western boundaries are formed by the eastern and the western ghats. 2. Its surface is even and the soil is very fertile. Its surface is uneven and rocky. The soil is not as fertile as in the Indo-Gangetic plain. 3. A fine network of the perennial rivers like Ganga, Indus, Krishna, Godavari, Mahanadi, Cauveri are the chief rivers. In this Brahmaputra flow through this plain. The rivers are also the useful region, these rivers are swift and make waterfalls so they are not for navigation, irrigation and generation of the hydroelectricity. navigable. These rivers are not perennial and go dry in the hot season. 4. 5. The Indo-Gangetic plain possesses the alluvial deposits transported The Deccan plateau is formed of the hard igneous and metamorphic by the Himalayan rivers. rocks. The South-west monsoons bring extensive rains in summer. While The Plateau is surrounded by the mountains on all the sides so the the eastern portion gets heavy rains, and the western portion is rainfall is scanty. comparatively dry. 6. 7. The Indo-Gangetic plain is well irrigated by the canals, wells and the Tanks are the chief means of irrigation. Storage canals carry water tube wells. from these tanks to the fields. The Indo- Gangetic plain is most densely populated plains of the The Deccan plateau is not thickly populated as is the Indo- Gangetic world. plain.
