2 Section A Cluster 4: Fieldwork (15 marks) 1 A group of 25 Geography students undertook an investigation about the flood risk along the Pekan River in Pekan, Malaysia which experiences a tropical monsoon (Am) climate. The students have decided to conduct the study at five sites which are selected at 500-metre intervals – Sites A, B C, D and E. They decided to collect the data on a weekday in June at 10am. The students were divided into five teams of five to collect data. At each site, the team gathered the primary data on channel cross-sectional area and river velocity with the following equipment: • 1 x Unweighted tape measure • 1 x Metre rule • 1 x Stopwatch • 1 x Orange (as floating device) • 2 x Ranging pole However, at Site A, the team lost their orange and used a small leaf found at the river bank as a floating device instead. Furthermore, during the fieldwork a heavy rain occurred. All teams had to halt their fieldwork and only managed to measure for river velocity once at each site. Resource 1 shows a map of the Sites A, B , C, D and E along Pekan River. Resource 2 shows a photograph of Site A. (a) With reference to Resource 1, suggest a research question for the geographical investigation. Explain your choice of research question. [4] (b) With reference to Resource 1, identify the sampling method used in selecting the sites for data collection and explain two benefits of this sampling method. [3] (c) With reference to Resource 2, suggest how the students could minimise potential risks during data collection. [4] (d) Explain why the data collected for river velocity at the various sites may not be accurate and reliable. [4]

3 Section B Cluster 2: Tropical Environments (30 marks) 2 Resource 3 shows the distribution of seasonally humid tropical savannah climates in Africa. Savannah climates can be subdivided into three categories – wet, dry and bush, depending on the length of the dry season. Resource 4 shows the climographs of three African cities, Tombouctou, Ouagadougou and Kisangani. Resource 5 shows the landuse cover in the Niger River Delta. (a) With reference to Resource 3, describe the distribution of seasonally humid tropical savannah climates. [4] (b) Explain the temperature characteristics of Kisangani shown in Resource 4. [4] (c) With reference to Resource 4, distinguish the rainfall patterns of the three cities in Africa. [6] (d) Using Resource 5, suggest how an increase in built-up areas in the Niger River Delta would affect its flows and storages within the drainage basin. [5] (e) Account for the shape of the Niger River Delta, shown in Resource 5. [6] (f) Explain the impact of human activities on the ecosystem services provided by deltas, such as the Niger Delta. [5]

4 Section C Answer EITHER Question 3 OR Question 4. Cluster 2: Tropical Environments (20 marks) 3 ‘Human factors are most significant in contributing to fluvial floods in the humid tropics.’ Evaluate this statement. [20] 4 ‘Climate is the most important factor influencing weathering processes in the tropics.’ Evaluate this statement. [20] - End of Paper -
