MARKSCHEME May 2002 GEOGRAPHY Higher Level Paper 3 10 pages M02/320/H(3)M+ INTERNATIONAL BACCALAUREATE BACCALAURÉAT INTERNATIONAL BACHILLERATO INTERNACIONALc Notes on individual questions SECTION A — TOPOGRAPHICAL MAPPING [7 marks] 1. (a) Draw a large sketch map of the a rea shown in the map extract to show the major landform features. To receive full marks, the sketch ma p should be accurate within the limits of time imposed by an examination, it s hould cover the area shown on the map extract, and should include some indi cation of approximate scale and clear labelling. It should also include an accurate indication of major landform features, which will probably include the caldera to the south-east of Christchurch, the flat land to the south-west of Christc hurch, the two large braided streams and smaller meandering streams and the hills in the north-west of the map extract and could include the major spit and lagoon. As a general rule, each of these four landform features should be awarded [1 mark], with the other [3 marks] being available for presen tation, labelling and showing details such as scale. To receive full marks, symbols us ed on the map should be unambiguous, through the use of a key (legend), by clear labelling or by using conventional symbols. [5 marks](b) Describe and explain the pattern of roads in the area shown. The pattern of roads is strongly influenced by the landforms in the area. This is shown by both the lower density a nd less well developed state of roads in the upland areas compared with the flatter plain [1 mark], and by the routes taken by roads, which tend to follow th e ridges and valleys on the caldera and are interrupted by several rivers [1 mark]. Main roads focus on the large settlement of Christchurch [1 mark]. There is a higher density of roads near the towns (especially Christchurch) due to the higher population densities in those areas and the need to access services in the towns [1 mark]. The remaining mark should be awarded wh ere candidates develop any of the points already noted (such as , for example, the triangular pattern giving way to a more rectangular pattern further away from Christchurch).
