A-level GEOGRAPHY PAPER 1 PHYSICAL GEOGRAPHY Mark scheme JUNE 2022 Specimen material v1.1 SPECIMEN MATERIAL A-level GEOGRAPHY PAPER 1 PHYSICAL GEOGRAPHY Mark scheme Specimen material v1.1 Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As preparation for standardisation each associate analyses a number of students’ scripts. Alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, associates encounter unusual answers which have not been raised they are required to refer these to the Lead Assessment Writer. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper. Further copies of this mark scheme are available from Level of response marking instructions Level of response mark schemes are broken down into levels, each of which has a descriptor. The descriptor for the level shows the average performance for the level. There are marks in each level. Before you apply the mark scheme to a student’s answer read through the answer and annotate it (as instructed) to show the qualities that are being looked for. You can then apply the mark scheme. Step 1 Determine a level Start at the lowest level of the mark scheme and use it as a ladder to see whether the answer meets the descriptor for that level. The descriptor for the level indicates the different qualities that might be seen in the student’s answer for that level. If it meets the lowest level then go to the next one and decide if it meets this level and so on, until you have a match between the level descriptor and the answer. With practice and familiarity you will find that for better answers you will be able to quickly skip through the lower levels of the mark scheme. When assigning a level you should look at the overall quality of the answer and not look to pick holes in small and specific parts of the answer where the student has not performed quite as well as the rest. If the answer covers different aspects of different levels of the mark scheme you should use a best fit approach for defining the level and then use the variability of the response to help decide the mark within the level, ie if the response is predominantly level 3 with a small amount of level 4 material it would be placed in level 3 but be awarded a mark near the top of the level because of the level 4 content. Step 2 Determine a mark Once you have assigned a level you need to decide on the mark. The descriptors on how to allocate marks can help with this. The exemplar materials used during standardisation will help. There will be an answer in the standardising materials which will correspond with each level of the mark scheme. This answer will have been awarded a mark by the Lead Examiner. You can compare the student’s answer with the example to determine if it is the same standard, better or worse than the example. You can then use this to allocate a mark for the answer based on the Lead Examiner’s mark on the example. You may well need to read back through the answer as you apply the mark scheme to clarify points and assure yourself that the level and the mark are appropriate. Indicative content in the mark scheme is provided as a guide for examiners. It is not intended to be exhaustive and you must credit other valid points. Students do not have to cover all of the points mentioned in the indicative content to reach the highest level of the mark scheme. An answer which contains nothing of relevance to the question must be awarded no marks. Section A Question 1 Water and carbon cycles 01 1 Explain the concept of dynamic equilibrium in relation to the water cycle. Allow 1 mark per valid point with extra mark(s) for developed points (d). AO1 • Dynamic equilibrium refers to the tendency towards a natural state of balance within the hydrological cycle (1). • The cycle is a closed system as no water enters or leaves the system; it is simply recycled around the system (d) (1). • The drainage basin element of the hydrological cycle is an open system where the inputs and outputs can change (d) (1). • The dynamic equilibrium is easily upset by extreme events such as storms or droughts (1). • Human activity can also cause disruption to the dynamic equilibrium, eg by modifying the drainage basin (1). • This causes disruption or interference to the dynamic equilibrium and is evidenced through flooding for example (1). • Such events and processes cause sudden changes in the state of the system and disrupt or interfere with dynamic equilibrium as is the case with flooding (1). 4 AO1=4 01 2 Using Figure 1, analyse projected rainfall change in Africa. AO3 – There are a variety of ways of approaching this unseen material. Students are required to analyse rainfall variation and change of over time. Responses should use the resources effectively and appropriately showing understanding of the link between the two graphs. Expect to see analysis of patterns and identification of anomalies on both the graphs and map. Mark scheme Level 2 (4–6 marks) AO3 – Clear analysis of the quantitative evidence provided, which makes appropriate use of data in support. Clear connection(s) between different aspects of the data and evidence. Level 1 (1–3 marks) AO3 – Basic analysis of the quantitative evidence provided, which makes limited use of data and evidence in support. Basic connection(s) between different aspects of the data and evidence. Notes for answers AO3 • Analysis shows that overall Africa is expected to see an increase in the amount of rainfall for most months. The biggest increases appear to be in January, April and November (around 4 mm). • However, from May to September, this model suggests that rainfall will be lower than the 1986–2005 average by as much as 4 mm in August. • Some students may calculate this as a reduction from 67 to 63 mm. For many months, February, March, May and September, there is little change expected. • The map gives further information about how the changes identified may affect rainfall spatially across Africa. The north of Africa is broadly expected to experience little change. • A large group of countries stretching from Chad to Botswana in the south are set to experience an increase in rainfall of up to 20 mm. • Some may point to anomalies where rainfall is set to fall such as south-west Nigeria which is expected to experience up to a 25 mm reduction in rainfall. 6 AO3=6 01 3 Using Figure 2 and your own knowledge, assess the natural and human induced causes of the 2005 flood in Carlisle. AO1 – Knowledge and understanding of the causes of floods in drainage basins. AO2 – Application of knowledge to the conditions in this drainage basin. Suggested causes should show an understanding of the conditions within this location and how these human and physical conditions affect the flooding. Mark scheme Level 2 (4–6 marks) AO1 – Demonstrates clear knowledge and understanding of concepts, processes, interactions and change. AO2 – Applies knowledge and understanding to the novel situation offering clear analysis and evaluation drawn appropriately from the context provided. Connections and relationships between different aspects of study are evident with clear relevance. Level 1 (1–3 marks) AO1 – Demonstrates basic knowledge and understanding of concepts, processes, interactions, change. AO2 – Applies limited knowledge and understanding to the novel situation offering basic analysis and evaluation drawn from the context provided. Connections and relationships between different aspects of study are basic with limited relevance. Notes for answers AO1 • Natural processes operating at hill slope level and in drainage basins. • Inputs and outputs, to include precipitation, runoff; stores and flows, to include interception, surface, soil water, groundwater and channel storage; stemflow, infiltration overland flow, and channel flow. Concept of water balance. • Human impact upon drainage basins to include farming practices and land use changes. • Runoff variation and the flood hydrograph. AO2 • Responses should note that prolonged periods of heavy rainfall prior to a storm appear to have contributed to the impact of antecedent rainfall. This antecedent rainfall referred to in the resource lead to full storage in groundwater and in the soil. Saturated ground prior to this event has exacerbated the impact 6 AO1=2 AO2=4
