Begin the answer to each question on a fresh sheet of paper. Write in dark blue or black pen. You may use a soft pencil for any diagrams, graphs or rough working. Do not use highlighters, glue or correction fluid. Answer all questions. You should make reference to appropriate examples studied in the field or the classroom, even where such examples are not specifically requested by the question. Diagrams and sketch maps should be drawn whenever they serve to illustrate an answer. The world outline map may be annotated and handed in with relevant answers. You are reminded of the need for good English and clear presentation in your answers. At the end of the examination, fasten all your work securely together. The number of marks is given in brackets [ ] at the end of each question or part question. You should spend time according to marks allocated to questions. All resources referred to in the question paper are in the Resource Booklet. This document consists of 6 printed pages

JC2H2PE2018 PAPER 2 2 SECTION A Answer the question below. The question carries 25 marks. Theme 4: Geographical Investigation 1 Sungei Kadut Industrial Estate is located in northwestern Singapore known for its furniture making and the manufac turing of automobile parts. It is located in close proximity to the Choa Chu Kang housing estate. A group of five junior college students we re tasked to carry out a geography fieldwork exercise at the Sungei Kadut Indust rial Estate to investigate the impact of these industries on the environment. The students decided to conduct pH and turbidity tests along the Pang Sua river to determine the water quality wi thin the industrial estate. Both pH and turbidity are significant measur es of water quality, whereby pH measures how alkali or ac idic the river is, while turbidity measures the concentration of particulate matter f ound in the river. Both the pH and turbidity are in turn a ffected by the nature of the effluence entering the river from the surrounding catchment area. The students chose five locations that were accessible by road for their data collection. As a group, the students moved from si te to site over the span of three hours on a Saturday morning to conduct their study. The equipment used by the students included: • White container for the water sample with Secchi disk sticker adhered to the base of the container (to measure turbidity) • 5 10ml test tubes • 10 pH test kit tablets • Indicator chart (to match turbidity and pH values) • Latex Gloves After the tests were completed, the data were compiled and analysed by the students so that conclusions c ould be made about t he impact of the Sungei Kadut Industrial Estate on the environment.

JC2H2PE2018 PAPER 2 3 Study Resources 1 and 2. Resource 1 is a map of the area around Sungei Kadut Industrial Estate and shows t he five locations where the students collected their data at. Resource 2 shows the procedure undertaken by the students at each sample site to measure pH and turbidity along the Pang Sua River. (a) Design a recording sheet that the students may use to collate their data collected across the different sites marked out in Resource 1. [3] (b) With reference to Resources 1 and 2, explain the limitations pertaining to the planning and data collect ion of the investigat ion. Suggest how these limitations can be overcome. [7] (c) Suggest how the students can mitigate the potential risks that may arise when undertaking this investigation. [3] (d) Explain why the group’s data may differ if they had conducted their investigation after a heavy thunderstorm. [4] (e) Suggest how the group of students can extend their investigation to examine the impact of Sungei Ka dut Industrial Estate on local communities. [8]

JC2H2PE2018 PAPER 2 4 SECTION B Answer the question below. The question carries 25 marks. Theme 1: Tropical Environments Climate Characteristics and Physical Processes in Australia 2 Resource 3 shows the climograph of Ca irns, Australia. Resource 4 shows the global average sea surface temperatures (SST) anomalies between 11 October 2015 and 7 November 2015. Re source 5 shows various physical processes that influence the climate of Australia. Resource 6 shows the effects of Tropical Cyclone Yasi on a town in Cairns in 2011. (a) With reference to Resource 3, briefly describe the climograph of Cairns. [2] (b) With the aid of a diagram and Resour ce 4, explain how the change in average sea surface temperatures in the Pacific Ocean between 11 October 2015 and 7 November 2015 could affect the weather conditions in Eastern Australia. [6] (c) Compare the tracks of Tropical C yclones George and Yasi shown in Resource 5. [3] (d) Suggest strategies that could be used to minimise the effects of flooding arising from the tropical cyclone shown in Resource 6. [5] (e) With reference to the resources pr ovided and your ow n knowledge, how far do you agree that the ITCZ is primarily responsible to explain the climate of Cairns? [9]

JC2H2PE2018 PAPER 2 5 SECTION C Answer the question below. The question carries 25 marks. Theme 2: Development, Economy and Environment Global Production Network of Semiconductors 3 Resource 7 shows the network connections and profits earned by countries in producing manufactur ed goods between 2000 and 2011. The size of the circle shows the profit earned for a country. The thickness of the line shows the intens ity of network connections between countries. Resource 8 traces the path of production of a semiconductor. Semiconductors, also known as microc hips, are the ‘brains’ of all modern electronics and drive the digital economy. They are critical to the function of a range of products from everyday consumer electronics like laptops and mobile phones, to sophisticated equi pment in economic sectors like aerospace and finance. Resource 9 s hows the spatial organisation of six major semiconductor transnational corporations in 2016. (a) Describe the changes in the pattern of network connections from 2000 to 2011 shown in Resource 7. [3] (b) Identify the change in Mexico’s prof its in manufactured goods between 2000 and 2011 shown in Resource 7 and suggest reasons for this change. [6] (c) Describe the spatial di stribution of the production circuit of the semiconductor shown in Resource 8. [3] (d) With reference to Resources 8 and 9, explain how the orga nisation of the semiconductor industry has benefitted USA. [4] (e) With reference to the resources prov ided, how far do you agree that USA is the most dominant player in the global semiconductor industry? [9]
