GEOGRAPHY (853) Aims 1. To enable candidates to acquire knowledge consequences of natural hazards and suggest (information) and to develop an understanding ways of coping with them through sustainable of facts, terms, symbols concepts, principles, development. generalizations, hypotheses, problems, trends, 3. To develop skills of drawing maps, surveying, processes and methods of Geography at the and drawing statistical diagrams and thematic national and global level. maps. 2. To apply the knowledge of the principles of 4. To develop an interest in Geography. Physical Geography in explaining the causes and CLASS XI There will be two papers in the subject: Population and Settlement, Economic, Political). Paper I – Theory (3 hours) ….70 marks – The conceptual and intellectual ideas of Paper II – Practical and Project Work …30 marks a number of new approaches to contemporary human geography should PAPER I: THEORY (70 Marks) be examined to understand the strengths There will be one Theory paper of three hours and limitations of each approach within duration divided into two parts: the context of Human Geography and Social Sciences. Part I (30 marks) will be compulsory and will consist of Section A and Section B. (ii) Regional approach: Regional/ Area Studies, Regional Planning, Regional Development. Section A will include compulsory short answer questions testing knowledge, application and skills Future prospects of Geography to be discussed: related to elementary/fundamental aspects of the • In the area of GPS, GIS, Remote Sensing for entire syllabus. resource identification. Section B will consist of one question on map work. • Applied geography in town and country Part II (40 marks) will consist of seven questions. planning, environment management and law, Candidates will be required to answer four out of cartography and mapping, geography seven questions. Each question in this part shall education, map analysis, travel and tourism carry 10 marks. (to be taught only for the sake of awareness, not for testing). GEOGRAPHY AS A DISCIPLINE PRINCIPLES OF PHYSICAL GEOGRAPHY 1. Geography - its interdisciplinary approach and future prospects 2. Formation of the Earth Geography as an integrating discipline. Physical Theories of formation; Methods of measuring age Geography and Natural Sciences; Geography and of the earth; Structure and Composition; Rocks. Social Sciences. (i) Theories of formation of the earth: the Big Branches of Geography: Bang theory.. (i) Systematic approach: Physical Geography (ii) Methods of measuring age of the earth: Tidal (Geomorphology, Climatology, Hydrology); force, Sedimentation, Rate of Erosion, Salinity Human Geography (Historical, Social, 51 of the Ocean, Radioactivity – a brief (iii) Vulcanicity – materials and processes. Major understanding. volcanic forms. (iii) Structure and composition of the earth’s Explanation of how volcanoes are formed; interior: crust, mantle, core; their properties - identification of the type of volcano; temperature, pressure, thickness. Sources of recognition of the properties of volcanic information – direct and indirect; seismic materials; explanation of why volcanoes are waves, their behaviour and inferences. more in the areas of converging plates. (iv) Rocks: Definition of rocks and minerals. The (iv) Earthquakes. mineral groups responsible for different rocks Origin of earthquakes, waves and their formed on the earth: silicates, carbonates, behaviour, hypocentre (focus), epicentre; sulphides, metals. their causes and distribution; effects; isoseismal and homoseismal lines, sea quakes, Classification of rocks by origin: igneous, tsunamis; measuring earthquakes and their metamorphic and sedimentary rocks – their intensity. distribution in India; characteristics, types, economic importance. Studying the effects of earthquakes on a country like Japan. The rock cycle. (v) Exogenetic process and associated landforms. 3. Changing Face of the Earth Weathering and gradation – difference Land forms and Processes of Gradation between the two. Role of weathering in (i) Endogenous processes: theory of plate gradation. Different types of weathering. tectonics and the process of drifting continents, (vi) Soil. theory of Isostasy by Pratt and A. Holmes.
