Day 6 Geography Qa Civil Service Corner TARGET OCS 2020 DAILY QUIZ DAY – 6 DATE : 29-09-2020 GEOGRAPHY Q Questions Answers Q1 Which of the following is the type of Correct Option: (d) plate Explanation: Option (d) is correct: ContinentContinent boundary of the Indian plate along the convergence is the type of Himalayan Mountains? plate boundary of the Indian plate along (a) Ocean-Continent Convergence the Himalayan mountains. (b) Divergent Boundary Supplementary notes: (c) Transform Boundary Movement of the Indian Plate The Indian plate includes (d) Continent-Continent Convergence Peninsular India and the Australian continental portions. The subduction zone along the Himalayas forms the northern plate boundary in the form of Continent-Continent convergence. In the east, it extends through the Rakinyoma Mountains of Myanmar towards the island arc along the Java Trench. The Western margin follows the Kirthar Mountain of Pakistan. It further extends along the Makrana coast and joins the spreading site from the Red Sea rift southeastward along the Chagos Archipelago. India was a large island situated off the Australian coast, in a vast ocean. The Tethys Sea separated it from the Asian continent until about 225 million years ago. India is supposed to have started her northward journey about 200 million years ago at the time when Pangaea broke. India collided with Asia about 40-50 million years ago causing rapid uplift of the Himalayas. About 140 million years before the present, the subcontinent was located as south as 50 degrees south latitude. The two major plates were separated by the Tethys Sea and the Tibetan block was closer to the Asiatic landmass. During the movement of the Indian plate towards the Asiatic plate, a major event that occurred was the outpouring of lava and formation of CIVIL SERVICE CORNER civilservicecorner.in https://t.me/CSCODISHA1 WHATSAPP- 7682092884 the Deccan Traps. Q2 Peninsular Rivers are characterised by: Correct Option: (d) (a) Fixed course of flow Explanation: Option (d) is correct: Peninsular (b) Absence of meanders Rivers are characterised by fixed (c) Non-perennial flow of water course, absence of meanders and nonperennial flow of (d) All of the above water. Supplementary notes: The Peninsular Drainage System The Peninsular drainage system is older than the Himalayan one. This is evident from the broad, largely-graded shallow valleys, and the maturity of the rivers. The Western Ghats running close to the western coast act as the water divide between the major Peninsular Rivers , discharging their water in the Bay of Bengal and as small rivulets joining the Arabian Sea. Most of the major Peninsular Rivers except Narmada and Tapi flow from west to east. The Chambal, the Sind, the Betwa, the Ken, the Son, originating in the northern part of the Peninsula belong to the Ganga river system. The other major river systems of the peninsular drainage are – the Mahanadi the Godavari, the Krishna and the Kaveri. Peninsular rivers are characterised by fixed course, absence of meanders and non-perennial flow of water. The Narmada and the Tapi, which flow through the rift valley, are exceptions.

  • Himalayan Geography: History, Society, and Culture
    Himalayan Geography: History, Society, and Culture Spring 2021, ANTH 0730 WEB Synchronous/Asynchronous T, 8 – 9 am EST via Zoom General Education Requirements: Social Science Specific Geographical Region Mr. Akshay Shah [email protected] Hanifl Center for Outdoor Education, Landour, India 1 COURSE DESCRIPTION The Himalayan region is characterized by a tremendous range of social and cultural diversity that corresponds to climatic, ecological and geographical variation, as well as local and regional geopolitical factors. Historical change from the emergence of early forms of social complexity centered on chiefs and their forts – from which the regional designation of “Garhwal” takes its name – through the development of kingdoms and larger polities, shows the intimate link between geography, environment and socio-political transformation. Similarly, local language patterns, regional religious practices, musical styles, mythology, food culture, sartorial fashion, architectural design, agricultural and transportation technologies and engineering and trade networks have all been shaped by the structure of mountain barriers, bounded valley communities and bracketed lines of communication that follow river systems. Whereas the political economy of the Himalayas has been structured around agricultural production, and the development of elaborate field terrace systems, there have also been subsidiary economies centered on trans-Himalayan trade and pilgrimage as well as pastoral nomadism and transhumance. Since the colonial period, the Himalayas have increasingly become a place for rest, relaxation, tourism and adventure, and this – along with further political transformations since Indian independence -- has led to the rapid development of urban areas. This course will provide a survey of Himalayan history, society and culture with a focus on the relationship between nature, the environment and geography.

NEGI CI N D U E INDUS PUBLISHING COMPANY NEW DELHI Preface The Himalaya are the most prominent feature on the face of the earth. They extend in an arcuate shape from the Indus gap in the north west to the Brahmaputra gap in the east. Jammu & Kashmir, Himachal Pradesh. Garhwal, Kumaun, Nepal, Darjeeling hills, Sikkim, Bhutan and most of Arunachal Pradesh lie in the Himalaya. Natural vegetation of this mountain chain is varied, both in compo sition and distribution. The principal forest types found in this mountain chain range from the wet evergreen forests in the eastern Himalayan foothills to the tropical dry forests ofJammu, the alpine meadows near the snowline and the open, stunted forests of the cold deserts. These forests and their adjoining tracts are the home of a large number of animals including tiger, leopard, snow leopard, clouded leopard, ele phant, rhinoceros, gaur, yak, Tibetan wild ass, sambhar, cheetal, musk deer, hog deer, barking deer, wild boar, brown and black bears, pheas ants, vultures, eagles, tits, warblers, snakes, crocodiles and jackals. This book discusses in briefthe mammals, birds, reptiles, fishes and amphibians found in different parts of the Hinrialaya. Importantnational parks,sanctuariesandbiosphere reservesset-uptoconserveandmanage the unique flora and fauna of this mountain chain havealso beendealt with in this book. It is hoped that this book will serve as a handy reference work on these topics for the foresters, wildlifers, naturalists, environmentalists and even the layman interested in knowing about the Himalayan wildlife and its management I am grateful to ShriA.K.

    An Overview of NWDA Presence in India Water Week-2017 An Overview of NWDA Involvement in Trade Fair-2017 2 From Director General’s Desk It gives me immense pleasure to present the Annual Jal Vikas-2018 issue of NWDA. The in-house bulletin of NWDA gives an overview of the main functions and objectives of NWDA in the field of Water Resources Planning and Development, particularly with respect to Inter Basin Water Transfer (IBWT) as well as Intra-State Water Transfer Projects commonly known as the Programme on Interlinking of Rivers (ILR), Government of India, under the Ministry of Water Resources, River Development and Ganga Rejuvenation (MoWR,RD&GR). It is pertinent to mention that the NWDA, with the support and guidance of Hon’ble Minister (WR, RD & GR) and Secretary (WR, RD &GR), has accomplished all its assigned functions in an efficient and effective manner during the year 2017, in spite of many hurdles and constraints especially relating to the shortage of Technical Officers. The main works dealt and completed by NWDA during the period of 1st January, 2017 to 31st December, 2017 and that indicated in the annual issue are related with the Techno-Economic Clearance and Water Sharing Issues of Ken-Betwa (Phase-I/II), Par- Tapi-Narmada and Damanganga-Pinjal Link Projects along with their Clearances from Wild Life, Environment, Forest Land Diversion, Ministry of Tribal Affairs (MoTA), Investment, Funding Pattern and Implementation Mechanism Departments. All the Clearances could be obtained mainly because of the concerted efforts taken by NWDA. In addition to these activities, NWDA also organized India Water Week-2017- the fifth event in the series during 10-14 October, 2017 by concurrently conducting the International Conference and Water Expo-2017; 3rd and 4th Jal Manthan respectively on 13.01.2017 and 27-28.07.2017; 64th Meeting of the Governing Body of NWDA on 27.03.2017; and 31st Annual General Meeting of NWDA on 12.09.2017.

As is well known, the description of the Saraswatl river, given in the Veda, differs much from that met with in the Hahabharata and other ancient but later authorities, while neither agrees with the present condition of that sacred stream. In the Rig Yeda we are told of a large and rapid river flowing from the mountains to the sea. The Mahabharata describes the same stream as losing itself in the sands. At the present day we find a river, wide and rapid during floods, but containing little water at other times, joining another stream of similar character, and thereupon losing its name; the river below the confluence being now called Gaggar.

Mycosphere 5(3), 440-461, Doi 10.5943/mycosphere/5/3/7 Abstract In the present study, the diversity, edibility, indigenous knowledge and distribution of wild edible mushrooms in the Northwestern Himalaya are discussed. The information provided herein was derived from a study carried out in the states of Uttarakhand and Himachal Pradesh during the period of 2000-2013. A total of 23 species of mushrooms considered as edible or used for trade were recorded. Twenty-one of these are basidiomycetes and two are ascomycetes. Certain species of Amanita, Agaricus, Astraeus, Hericium, Macrolepiota, Morchella, Pleurotus and Termitomyces are very commonly collected and consumed by the local people, whereas species of Auricularia, Cantharellus, Sparassis, Lactarius, Ramaria and Russula are less commonly collected and consumed. Cordyceps sinensis and several species of Morchella are collected specifically for trade purposes in the spring season in high elevation areas of the Himalaya.
