MARK SCHEME for the October/November 2011 question paper for the guidance of teachers
9696 GEOGRAPHY
9696/11 Paper 1 (Core Geography), maximum raw mark 100
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 October/November 2011 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses.

Paper 11
1
(a) Calculate the lag time. 5–7 hours (b) Identify the following features of the hydrograph. (i) A rising limb (ii) B peak discharge (iii) C baseflow [3] [1]
(c) Explain how two of the catchment conditions given in Fig.1 affect the shape of the hydrograph. – – – Clay allows little infiltration as it gets saturated quickly and therefore the more water would form overland flow. The steep sided topography means that water will flow quickly into the channel contributing to the high level of run off. The rounded drainage basin shape means that all the points from the watershed are approximately equidistant from the point where the discharge was recorded. In all cases the effects on the hydrograph are similar i.e. a relatively short lag
