UNIVERSITY OF CAMBRIDGE INTERNATIONAL EXAMINATIONS International General Certificate of Secondary Education MARK SCHEME for the May/June 2011 question paper for the guidance of teachers 0460 GEOGRAPHY 0460/05 Paper 5 (Computer Based Alternative to Coursework), maximum raw mark 60 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes must be read in conjunction with the question papers and the report on the examination. • Cambridge will not enter into discussions or correspondence in connection with these mark schemes. Cambridge is publishing the mark schemes for the May/June 2011 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses. www.theallpapers.com

Page 3 Mark Scheme: Teachers’ version Syllabus Paper IGCSE – May/June 2011 0460 05 © University of Cambridge International Examinations 2011 8 A major settlement (a) lower course (b) land is flat so easy to build on/farm on; nearer sea so settlement may have developed as a port/holiday resort (NOT water supply) A reservoir with an HEP scheme (c) Upper course OR middle course (d) Upper course reasons: higher land so more rainfall; steep sided valleys to make building of a dam easier; river flowing down steeper gradient giving more energy; less human impact needed. Middle course reasons: wider river so more water flowing into it. [4] (1 mark per correct location/reason. Allow a reason mark even if location incorrect) [E] 9 C (measuring tape) and F (ranging poles) [2] (1 mark per correct answer) [C] 10 (a) Site 3 = 21 (no tolerance) (b) Site 5 = 35 (no tolerance) [2] (1 mark per correct answer) [E] 11 River may be too deep; river may be too fast/have a strong current; river may be too wide; need more than one measurement (one is not enough to get an accurate measurement); the mid-point may not be the deepest point; there may be an obstruction at the mid-point/pole may sink in river bed; it’s hard to find the exact mid-point of a river. [2] (1 mark per correct answer) [E] 12 (a) A (Yes/agree with hypothesis) (1 mark) (b) Near the source (site 1), the river is narrow and shallow (0.42 m wide and 8 cm deep). However, near the mouth (site 7) the river is wider and deeper (3.69 m wide and 83 cm deep). (3 marks) [4] (1 mark for a correct statement naming sites or proximity to source/mouth/downstream and judgement of change – wider/deeper etc. But NO mark for repeat of hypothesis; 2 marks for correct use of data – pairs of data needed – no need for units) [E] www.theallpapers.com

Page 4 Mark Scheme: Teachers’ version Syllabus Paper IGCSE – May/June 2011 0460 05 © University of Cambridge International Examinations 2011 13 Description (up to 2 marks): systematic sampling is when samples are taken at regular intervals/equal distances apart. They could pick up every 10th piece of bedload – in order to get 5 samples. Or they could use a quadrat and use the 10th, 20th etc. squares. Or they could use a bedload sampler at each point and measure the first five pieces. (1 mark for saying regular intervals and 1 mark for description) Explanation of reliability (1 mark): it is a reliable method as it rules out bias/choosing of sample/is a fair test and it means that the sample is the most representative for the site. [3] [Answer does not have to relate to rivers] [E] 14 (a) Site 3 = 11.5 cm (allow tolerance of 0.1 – so 11.4–11.6); (b) Site 5 = 3.7 cm (allow tolerance of 0.1 – so 3.6–3.8) (c) Average site 6 = 2.16 cm (allow 2.2) [3] (1 mark per correct answer) [E] 15 (a) B (No/disagree with hypothesis) (1 mark) (b) Near the source (site 1), the bedload is larger (average of 24.4 cm). However, near the mouth (site 7) the bedload is smaller (average of 1.02 cm) (3 marks) [4] (1 mark for saying a new hypothesis “As the river gets closer to the sea, the size of the material on the river bed decreases”. 1 mark for correct statement naming sites/proximity to source and mouth/downstream. 1 mark for correct use of paired data – no need for units). [E] 16 (a) Shape: bedload gets rounder/less jagged/less sharp/smoother. (1 mark) [NOT smaller/anything to do with size] (b) Explanation: because pieces of the bedload hit each other and pieces are broken off – attrition; the bedload is dragged rolled along the river bed – traction; the bedload is thrown against the banks – corrasion/abrasion; the bedload is picked up by the river and then dropped/bounced along the river bed – saltation; the force of the water erodes the bedload – hydraulic action (2 marks) [3] (2 marks for naming 2 methods or 2 marks for explaining two – or a combination) (NOT solution/corrosion) [E] www.theallpapers.com
