Question 1: Fieldwork Investigation [20 marks]

A group of students investigated the hypothesis: "Stream velocity increases downstream along River Valley."

They selected 4 sites along the river, each 500m apart. At each site, they measured stream velocity using a flow meter at 3 points across the river width. The study was conducted on one day in March during dry weather conditions.

Study Table 1.1, which shows their results.

Site	Distance downstream (m)	Velocity Reading 1 (m/s)	Velocity Reading 2 (m/s)	Velocity Reading 3 (m/s)	Mean Velocity (m/s)
A	0	0.8	0.9	0.7	0.8

Question 1: Fieldwork Investigation [20 marks]

(a) Calculate the mean velocity at Site D. Show your working. [2]

Working: (2.1 + 2.3 + 1.9) ÷ 3 = 6.3 ÷ 3 (1 mark) Answer: 2.1 m/s (1 mark)

(b) Suggest how the students could display the relationship between distance downstream and mean velocity on one graph. [3]

Answer:

• Line graph/scatter plot (1 mark)
• Distance downstream on x-axis (horizontal axis) (1 mark)
• Mean velocity on y-axis (vertical axis) with appropriate scale and units (1 mark)

(c) Describe the pattern shown by the mean velocity data in Table 1.1. [3]

Answer:

• Stream velocity increases downstream (1 mark)
• Steady/consistent increase from 0.8 m/s to 2.1 m/s (1 mark)
• Velocity increases by approximately 0.4 m/s every 500m / Linear increase (1 mark)

(d) Explain why the students took three velocity readings at each site rather than just one. [2]

Answer:

• To improve reliability/accuracy of results (1 mark)
• To account for variations across river width / Calculate mean to reduce impact of anomalous readings (1 mark)

(e) Suggest two factors, other than distance downstream, that could affect stream velocity. [4]

Sample answers: (2 marks per factor - 1 for identification, 1 for explanation)

Factor 1: Channel depth/width Explanation: Deeper/narrower channels increase velocity due to reduced friction with riverbed/banks

Factor 2: Gradient/slope of river Explanation: Steeper gradients increase gravitational force, causing water to flow faster

Alternative factors: Rainfall/discharge, channel roughness, obstacles/vegetation, seasonal variations

(f) Evaluate whether the data collection method provides reliable results. [6]

Mark Scheme:

• Level 1 (1-3 marks): Basic evaluation with limited development
• Level 2 (4-6 marks): Clear evaluation with good justification and balanced argument

Sample Answer: The data collection method provides partially reliable results. Strengths: Taking three readings at each site and calculating the mean improves accuracy by reducing the impact of anomalous readings. The systematic sampling at 500m intervals provides consistent spacing and covers a good range of the river. Using a flow meter provides standardized measurements.

Weaknesses: Conducting the study on only one day limits reliability as river conditions vary daily due to rainfall and seasonal factors. Dry weather conditions may not represent typical flow patterns. Only 4 sites may be insufficient to establish a clear trend - more sites would strengthen the pattern.

Conclusion: The method has good structure but would be more reliable with data collection over multiple days and weather conditions to account for temporal variations.

Question 2: Tourism Development [15 marks]

(a) Describe the trend in tourist arrivals to Country X from 1990 to 2020. [3]

Sample Answer:

• Overall increasing trend (1 mark)
• Rapid growth from 1990 to 2000, then slower growth (1 mark)
• Slight decline/plateau around 2008-2010, then recovery and continued growth to 2020 (1 mark)

(b) Suggest two economic benefits that increased tourism may bring to Country X. [4]

Sample answers:

Benefit 1: Job creation/employment opportunities Explanation: Tourism creates direct jobs in hotels, restaurants, transport and indirect jobs in construction, agriculture supplying tourist facilities

Benefit 2: Foreign exchange earnings Explanation: Tourist spending brings foreign currency which improves balance of payments and can be used to import goods/technology

Alternative benefits: Tax revenue, infrastructure development, multiplier effect

(c) Explain how tourism development can lead to environmental degradation. [4]

Sample Answer:

• Increased construction of hotels and facilities leads to habitat destruction and loss of biodiversity (1 mark)
• Higher visitor numbers cause trampling of vegetation and soil erosion on popular trails/beaches (1 mark)
• Increased waste generation and sewage from tourists can pollute water sources and marine environments (1 mark)
• Transportation (flights, cars) increases carbon emissions contributing to climate change (1 mark)

(d) "Ecotourism is more sustainable than mass tourism." How far do you agree? [4]

Mark Scheme:

• Level 1 (1-2 marks): Basic agreement/disagreement with limited justification
• Level 2 (3-4 marks): Clear position with good justification and examples

Sample Answer: I partially agree that ecotourism is more sustainable than mass tourism. Agree: Ecotourism involves smaller visitor numbers which reduces environmental pressure and allows natural recovery. It focuses on conservation education, creating awareness about environmental protection. Revenue often directly funds conservation projects, as seen in Costa Rica's national parks.

However: Ecotourism can still cause damage if poorly managed - even small groups can disturb wildlife. Mass tourism can be sustainable if well-planned, such as Singapore's integrated resort model which includes environmental controls. Conclusion: Ecotourism has greater potential for sustainability, but success depends on proper management and regulation in both cases.

Question 3: Climate and Weather [15 marks]

(a) State the approximate global temperature anomaly in 2020. [1]

Answer: +1.0°C (accept +0.9°C to +1.1°C) (1 mark)

(b) Describe the pattern of global temperature anomalies shown in Figure 3.1. [3]

Sample Answer:

• Overall warming trend from 1880 to 2020 (1 mark)
• Relatively stable/slight cooling from 1880 to 1980 (1 mark)
• Rapid warming from 1980 onwards, with most recent decades showing highest anomalies (1 mark)

(c) Explain how human activities contribute to the enhanced greenhouse effect. [5]

Sample Answer:

• Burning fossil fuels (coal, oil, gas) releases carbon dioxide into the atmosphere (1 mark)
• Deforestation reduces CO2 absorption by trees, increasing atmospheric CO2 concentration (1 mark)
• Agriculture and livestock farming release methane, a potent greenhouse gas (1 mark)
• Industrial processes release other greenhouse gases like nitrous oxide and CFCs (1 mark)
• These gases trap more longwave radiation from Earth's surface, increasing global temperatures beyond natural greenhouse effect (1 mark)

(d) "Climate change is the most serious environmental challenge facing the world today." To what extent do you agree? [6]

Mark Scheme:

• Level 1 (1-3 marks): Basic argument with limited development and few examples
• Level 2 (4-6 marks): Well-developed argument with good examples and balanced evaluation

Sample Answer: I largely agree that climate change is the most serious environmental challenge, but other issues are also critical.

Agree: Climate change has global impacts affecting all countries through sea level rise (threatening small island states like Maldives), extreme weather events (hurricanes, droughts causing food insecurity), and ecosystem disruption (coral bleaching, species extinction). It acts as a threat multiplier, worsening other environmental problems. The scale is unprecedented and potentially irreversible.

However: Other challenges are equally serious in specific contexts. Plastic pollution directly kills marine life and enters food chains. Air pollution causes immediate health impacts, killing millions annually in cities like Delhi. Biodiversity loss threatens ecosystem services essential for human survival.

Conclusion: Climate change is among the most serious challenges due to its global scale and interconnected impacts, but it must be addressed alongside other environmental issues as they are interconnected. The "most serious" depends on geographical context and timeframe.
