The subject of Geography has changed considerably over time and it continues to change because it is one of the most dynamic subjects in the curriculum. The Earth and its atmosphere, the home of humankind, is changing all the time and that is what makes our subject so special. This guide must be used in conjunction with the main textbook, as it is a summary of the main components of the textbook. Geography, like any other subject, does contain facts which must be understood and learnt, but it also emphasises skills. It is necessary for the learner to analyse and use these facts to understand phenomena and to try to solve problems. Our lives depend on the ways in which we treat our environment. Thus, as citizens of the Earth, we must understand the changes that are constantly taking place and our own impact on our surroundings. Geography is all around us at all times. Get into the habit of looking at a city, town, village, landscape and trying to work out the processes that act on it. Why is that shop there, why are there so many people there, why is that hill shaped liked that, how is that river being used? These are the sort of questions that you must get into the habit of asking yourself and trying to answer. Do this regularly and you will be a much better Geographer. Once you have studied the detail in the main textbook, use this guide as a summary. Concentrate on the key concepts and build your knowledge around them. Do this regularly and you will develop into a genuine geographer ready to take your place as a keeper of our vital environment. © Via Afrika Publishers » Geography 11 Study Guide eBook 111 Introduction to geographical skills and techniques Introduction to geographical skills and techniques Introduction The aim of this topic is to explain the good skills and techniques you need to become geographically literate and to develop a sense of the spaces and area around you. Maps are the language of geography. To become a good map user you must be familiar with the necessary skills and techniques. You also need to be able to apply them in everyday situations. Unit 1 Mapwork skills 1 Locating exact position (revision) You can find any place on Earth by finding the point at which its line of latitude and line of longitude intersect. All of South Africa is south of the equator and east of the Prime Meridian through Greenwich in England. FIIGUREGURE 1 The relationship between degrees, minutes and seconds Each degree (ºººº) can be subdivided into 60 minutes ('''') and each minute divided into 60 seconds (""""). This subdivision enables us to determine the position of any place or object very accurately. The geographic coordinates must be described in full as degrees, minutes, and seconds South and East. © Via Afrika Publishers » Geography 11 Study Guide eBook 222 Introduction to geographical skills and techniques FIIGUREGURE 2 How to write a co-ordinate correctly 2 Locating relative position (revision) 2.1 What is direction?

    A Sense of Place: Human Geography in the Early Childhood Classroom

    Social Studies: From a Sense of Self to a Sense of the World Pamela Brillante and Sue Mankiw Preschool Through Primary Grades A Sense of Place: Human Geography in the Early Childhood Classroom Walking downtown is four-year-old Abby’s favorite thing to do with her dad. Today is the first day that Abby hasn’t had to wear a coat on their walk. They walk under shady trees and stop to notice all the white flowers blooming outside the library where Abbey and her grandma go for story hour with Abby’s friends. The smell of lilies of the valley permeates the air. As they get closer to downtown, Dad picks Abby up while they cross the broken sidewalk near the post office so she does not get hurt on the rough terrain. It can be difficult for her to navigate uneven ground with her walker. Approaching the town’s music stage, Abby tugs on her dad’s sleeve; she wants to hear the musicians playing their shiny instruments. Abby points out the sign that says STOP on the busy street corner by Poppy’s Bakery. The nice women who work there always talk to Abby and let her pick out a cookie while her dad buys warm, delicious-smelling bread for Sunday dinner. Abby loves going to “her downtown,” where she knows she is part of the community of friends, neighbors, and merchants she meets along the way. 1, 2, 3 ® © iStock.com/ktaylorg 2 Young Children July 2015 lthough they may not realize it, Abby physical world around them and in the social and cultural and her dad are studying geography on their world they share with others.

Soft rock erodes away more quickly than hard rock. 4. The dip slope is 10–25° to the horizontal. Folding can result in cuesta basins and cuesta domes. 5. Farming can take place on dip slopes. Roads and railways can be built parallel to these landscapes. Gaps or poorts between homoclinal ridges can be good sites to build dams. Cuesta basins yield artesian water. Cuesta domes may contain oil and natural gas (fracking). Fertile valleys and plains between cuestas are suitable for human settlements. These ridges are used for forestry, tourism, recreation and nature conservation. These ridges can be used for defence purposes. (Accept any relevant answer) ACTIVITY 8 – MARKING GUIDELINE: 1. It occurs when strata are subjected to stress (compression, tension, volcanic intrusion, or tectonic movement) and they become tilted relative to their original (horizontal) position. Faulting or folding causes the strata to be tilted. The beds may be inclined in any direction with the angle of the dip slope between 0º to 90º. 2. Cuesta dome 3.

The Tri-State Geological Field Conference was founded in 1933 as an informal geological field trip for professionals and students in Iowa, Illinois and Wisconsin. The first Tri-State examined the LaSalle Anticline in Illinois. Fifty-two geologists from the University of Chicago, University of Iowa, University of Illinois, Northwestern University, University of Wisconsin, Northern Illinois State Teachers College, Western Illinois Teachers College, and the Illinois State Geological Survey attended that trip (Anderson, 1980). The 1934 field conference was hosted by the University of Wisconsin and the 1935 by the University of Iowa, establishing the rotation between the three states. The 1947 Tri-State visited quarries at Hamilton Mound and High Cliff, two of the stops on this year’s field trip.

    49 Chapter 5 Topographical Maps

    Topographical Maps Chapter 5 Topographical Maps You know that the map is an important geographic tool. You also know that maps are classified on the basis of scale and functions. The topographical maps, which have been referred to in Chapter 1 are of utmost importance to geographers. They serve the purpose of base maps and are used to draw all the other maps. Topographical maps, also known as general purpose maps, are drawn at relatively large scales. These maps show important natural and cultural features such as relief, vegetation, water bodies, cultivated land, settlements, and transportation networks, etc. These maps are prepared and published by the National Mapping Organisation of each country. For example, the Survey of India prepares the topographical maps in India for the entire country. The topographical maps are drawn in the form of series of maps at different scales. Hence, in the given series, all maps employ the same reference point, scale, projection, conventional signs, symbols and colours. The topographical maps in India are prepared in two series, i.e. India and Adjacent Countries Series and The International Map Series of the World. India and Adjacent Countries Series: Topographical maps under India and Adjacent Countries Series were prepared by the Survey of India till the coming into existence of Delhi Survey Conference in 1937. Henceforth, the preparation of maps for the adjoining 49 countries was abandoned and the Survey of India confined itself to prepare and publish the topographical maps for India as per the specifications laid down for the International Map Series of the World.

GEOLOGY- A FASCINATING DISCIPLINE OF NATURAL SCIENCE Our home planet “The Earth” is a member of the solar system. Also known as the ‘Blue Planet’, it is the only heavenly body of revolution that has a delicate balance of physico-chemical conditions, which support sustenance of life that is unique and special. Geology is a natural scientific discipline and is a term derived from the summation of two ‘Greek’ words such as ‘Ge or Geo’ meaning the earth and ‘Logos’ meaning science or discourse. It pertains to the study of the earth as a whole or part thereof. In a broader sense, geology could be reframed as ‘Earth Science’ which considers the whole earth as closed system, which is ever dynamic and a mosaic of four interactive parts that are ever changeable both among and within them. These four parts are called four reservoirs of materials of the earth (Fig.1.1) which also represent the four open systems such as (i) THE ATMOSPHERE which surrounds the – earth’s surface as a continuous canopy (layer) composed of a gaseous mixture of nitrogen (N), oxygen (O), hydrogen (H), carbon Fig.1.1: Reservoirs of earth materials and transfer of energy - 1 - BilimTook.com dioxide (CO2) and water vapour (H2O↑). (ii) THE HYDROSPHERE which forms the storehouse of earth’s total water regime comprising the oceanic and sea water, stream (river) water, lake water, surface run-offs, frozen water in form of snow and ice, and underground water (iii) THE GEOSPHERE, which is the solid earth composed of soils, regolith (loosely cemented rock particles), solid rocks, layers of rock-metal association and metallic alloys (Fe-Ni), as is observed and interpreted from the top towards the centre of the earth.
  • The Relevance of Spatial Relation Terms and Geographical Feature Types

    The Relevance of Spatial Relation Terms and Geographical Feature Types

    The Relevance of Spatial Relation Terms and Geographical Feature Types Chunju Zhang Xueying Zhang Key Laboratory of Virtual Geography Environment (Nanjing Normal University), MOE, Nanjing, China [email protected] Abstract: Spatial relation terms can generally indicate spatial relations de- scribed in natural language context. Their semantic representation is closely re- lated to geographical entities and their characteristics e.g. geometry, scale and geographical feature types. This paper proposes a quantitative approach to ex- plore the semantic relevance of spatial relation terms and geographical feature types of geographical entities in text. Firstly, a classification of spatial relation terms is performed. Secondly, the “Overlap” similarity measure is introduced to define the relevance of spatial relation terms and geographical feature types based on a large scale annotation corpus. Finally, a knowledge base based on protégé is developed to formally represent and visualize geographical feature types, spatial relation classifications, and the relevance of spatial relation terms and geographical feature types. This study indicates that spatial relation terms are strongly relevant to geographical feature types. The semantic representation of topological relation terms is diverse and their relevance with geograph- ical feature types is much stronger than directional relation and distance rela- tion terms, but the annotation quality and the classification granularity of geo- graphical entities in the corpus have a great effect on the performance. Keywords: spatial relation; geographical feature type; spatial relation term; relevance 1 Introduction Natural language describes the nature of people’s internal representation of space and is the primary means for representation and exchange of geographical infor- mation, such as geographical entities, spatial relations, etc.
