Answer:
- The land is hilly / has high relief.
- Contour lines are closely spaced, indicating steep slopes.
- The highest point is approximately ___ m (accept any reasonable spot height from the map).
Marking note: Award 1 mark for identifying the land as hilly/high, and 1 mark for referencing contour spacing or a specific height. Answers must refer to evidence from the map.
(d) State two pieces of evidence from the map that suggest the area is used for residential purposes. [2]
Answer:
- Evidence 1: Presence of roads/streets in a grid pattern.
- Evidence 2: Presence of buildings marked on the map / housing blocks / residential flats.
(Alternative acceptable answers: presence of schools, parks, car parks, or other community facilities associated with residential areas.)
Marking note: Award 1 mark for each valid piece of map evidence. Answers must be observable from the map, not inferred.
(e) A student wants to build a new community park in the area. Suggest a suitable grid square and explain your choice with reference to two map features. [3]
Grid square: (Accept any reasonable grid square, e.g., 4678)
Explanation:
- The grid square is flat / low-lying (contour lines are widely spaced), making it suitable for construction.
- It is near residential areas / housing estates, so it would be accessible to residents.
- It is not currently occupied by other major land uses (e.g., not a river, forest, or industrial area).
Marking note: Award 1 mark for a valid grid square, and 2 marks for two well-explained reasons with reference to map features. Answers must link the choice to specific map evidence.
Question 2
(a) Identify the coastal landform labelled X in the photograph. [1]
Answer: Headland (Accept: cliff, stack, bay — depending on what X labels in the photograph)
Marking note: Award 1 mark for correct identification of the landform.
(b) Describe two features of the landform at X that can be seen in the photograph. [2]
Answer:
- Feature 1: Steep, vertical rock face / cliff.

Marking note: Award 1 mark for each feature that is visible in the photograph. Answers must describe what can be seen, not explain processes.
(c) Explain how the landform at X is formed. [3]
Answer:
- Waves erode the base of the cliff through hydraulic action (force of water compressing air in cracks) and abrasion (rocks and sediment grinding against the cliff face).
- A wave-cut notch is formed at the base of the cliff.
- Over time, the notch deepens, creating an overhang that eventually collapses under its own weight.
- This process of erosion and collapse causes the cliff to retreat inland, forming a steep headland or stack.
Marking note: Award 1 mark for identifying the type of erosion (hydraulic action/abrasion), 1 mark for describing the formation of the wave-cut notch, and 1 mark for explaining cliff retreat/collapse. Answers must use geographical terminology.
(d) Suggest one reason why the area shown in the photograph might be at risk of coastal erosion. [1]
Answer: The area is exposed to strong waves / high-energy waves from the open sea / prevailing winds, which increase the rate of erosion.
(Alternative: The rock type is soft / easily eroded, e.g., sandstone or clay.)
Marking note: Award 1 mark for a valid reason linked to wave energy, rock type, or exposure.

- Rainfall decreases from April to July, reaching the lowest level of about 80 mm.
- It then increases again from July to October, reaching a second peak of about 320 mm.
- Rainfall decreases from October to December.
Marking note: Award 1 mark for describing the overall bimodal pattern, 1 mark for referencing specific months or values, and 1 mark for describing the trend across the year. Answers must include data from the graph.
(e) Explain why this city experiences a bimodal rainfall pattern. [3]
Answer:
- The city is located near the equator, where the Intertropical Convergence Zone (ITCZ) passes over twice a year.
- When the ITCZ passes over (around April and October), it brings convective rainfall due to intense heating and rising air.
- Between these periods (around July), the ITCZ moves away, and the area comes under the influence of dry trade winds / subtropical high pressure, resulting in lower rainfall.
Marking note: Award 1 mark for mentioning the ITCZ, 1 mark for explaining the twice-yearly passage, and 1 mark for linking it to convection/rainfall. Answers must demonstrate understanding of atmospheric processes.

**(e)** Suitable grid square for a new community park: [3]
- **Grid square:** *(Accept any valid grid square, e.g., **4678**)*
- **Explanation:** The grid square is suitable because:
1. It is **flat land** (widely spaced contour lines), making it easy to develop.
2. It is **near residential areas/roads**, making it accessible to the community.
---
### Question 2
**(a)** Coastal landform labelled **X**: [1]
- **Answer:** **Headland** *(Accept: **Bay**, depending on assumed photograph)*
**(b)** Two features of the landform at **X**: [2]
- **Feature 1:** **Steep, rocky cliffs** rising from the sea.
- **Feature 2:** **Wave-cut platform/notch** at the base of the cliff.
**(c)** Formation of the landform at **X**: [3]
- **Answer:** A headland is formed through **differential erosion**. The sea attacks **softer/less resistant rock** (e.g., clay) more quickly than **harder/more resistant rock** (e.g., granite). Over time, the softer rock is eroded to form **bays**, while the more resistant rock remains as a **headland** jutting out into the sea. Processes include **hydraulic action** (force of waves compressing air in cracks), **abrasion** (rocks and pebbles grinding against the cliff), and **corrosion/solution** (chemical erosion of rock).
**(d)** Reason why the area might be at risk of coastal erosion: [1]
- **Answer:** The area is exposed to **strong waves/long fetch**, which increase the rate of erosion. *(Accept: presence of soft rock, lack of coastal defences, rising sea levels, etc.)*

**(d)** Pattern of rainfall from January to December: [3]
- **Answer:** The rainfall pattern is **bimodal**, with **two peaks** in **April** and **October**. Rainfall is **lower** in **February** and **July**. Rainfall **increases** from February to April, **decreases** from April to July, **increases** again from July to October, and then **decreases** from October to December.
**(e)** Explanation of bimodal rainfall pattern: [3]
- **Answer:** The city is located near the **equator** in Southeast Asia. The bimodal pattern is caused by the **passage of the Inter-Tropical Convergence Zone (ITCZ)**. The ITCZ passes over the area **twice a year** — once when it moves **northward** (around April) and once when it moves **southward** (around October). When the ITCZ is overhead, there is **intense convectional rainfall** due to the convergence of warm, moist air masses. Between these periods, the ITCZ moves away, resulting in **drier conditions**.

### Question 6
**(a)** City with the **largest absolute increase** in population: [1]
- **Answer:** **City R** (increase = 3.0 − 2.5 = 0.5 million; City P = 0.6 million — **City P** has the largest absolute increase of 0.6 million)
- **Corrected Answer:** **City P** (increase = 1.8 − 1.2 = **0.6 million**)
**(b)** Percentage increase in population for **City S**: [2]
- **Working:** ((0.9 − 0.5) / 0.5) × 100 = (0.4 / 0.5) × 100 = **80%**
- **Answer:** **80%**
**(c)** City with the **smallest percentage increase**: [3]
- **Working:**
- City P: ((1.8 − 1.2) / 1.2) × 100 = 50%
- City Q: ((1.1 − 0.9) / 0.9) × 100 = 22.2%
- City R: ((3.0 − 2.5) / 2.5) × 100 = 20%
- City S: ((0.9 − 0.5) / 0.5) × 100 = 80%
- City T: ((1.7 − 1.6) / 1.6) × 100 = 6.25%
- **Answer:** **City T** (6.25%)
**(d)** Two reasons for rapid population growth in developing country cities: [2]
- **Reason 1:** **Rural-to-urban migration** — people move to cities in search of better employment opportunities, education, and healthcare.
- **Reason 2:** **High birth rates/natural increase** — the population grows due to a high birth rate and/or declining death rate due to improved healthcare.

### Question 7
**(a)** Annual temperature range for Town M: [2]
- **Working:** Highest temperature − Lowest temperature = 30°C − 25°C = **5°C**
- **Answer:** **5°C**
**(b)** Relationship between temperature and rainfall: [2]
- **Answer:** When temperatures are **higher** (around March–May and September–November), rainfall is also **higher**, indicating a **positive correlation**. The warmer months experience more **convectional rainfall** due to increased evaporation and convection. During the slightly cooler months (June–September), rainfall is **lower**.
**(c)** Effect of equatorial location on climate: [3]
- **Answer:** Town M is located near the **equator**, where the sun is **almost directly overhead** throughout the year. This results in **high temperatures year-round** (small annual temperature range). The intense heating causes **convectional rainfall** daily or regularly. The area lies within the **Inter-Tropical Convergence Zone (ITCZ)**, where trade winds converge, causing warm, moist air to rise and produce heavy rainfall.
**(d)** One way the climate affects daily lives: [1]
- **Answer:** Residents may need to carry **umbrellas/raincoats** regularly due to frequent rainfall, or plan outdoor activities around the **wet and dry seasons**. *(Accept: clothing choices, housing design, agricultural practices, etc.)*

### Question 8
**(a)** Relationship shown in the scatter graph: [2]
- **Answer:** There is a **positive correlation** between GDP per capita and literacy rate. As GDP per capita **increases**, the literacy rate also **increases**. Most data points are clustered along a **line of best fit** from bottom-left to top-right.
**(b)** Term for this type of relationship: [1]
- **Answer:** **Positive correlation**
**(c)** One outlier and reason: [2]
- **Outlier:** *(Accept any reasonable identification, e.g., a country with high GDP per capita but low literacy rate)*
- **Reason:** The country may have **wealth from natural resources** (e.g., oil) that has not been invested in **education**, or there may be **social/political barriers** preventing access to education despite economic wealth.
**(d)** Why GDP per capita may not be a reliable indicator of overall development: [2]
- **Answer:** GDP per capita is an **average** and does not show the **distribution of wealth** within a country. A high GDP per capita may mask **income inequality**, where a small elite is very wealthy while the majority live in poverty. It also does not account for other aspects of development such as **healthcare, education quality, life expectancy, political freedom, or environmental sustainability**.

### Question 9
**(a)** Type of river valley shown: [1]
- **Answer:** **V-shaped valley**
**(b)** Two features of the river valley: [2]
- **Feature 1:** **Steep valley sides** formed by vertical erosion.
- **Feature 2:** **Narrow floodplain** (or absence of a wide floodplain) at the base of the valley.
**(c)** Formation of the V-shaped valley by river processes: [3]
- **Answer:** A V-shaped valley is formed in the **upper course** of a river where the river has **high energy** and flows **quickly** down a steep gradient. The main process is **vertical erosion** (also called **downcutting**), where the river erodes **downward** into its bed. Processes include **hydraulic action** (the force of water dislodging material), **abrasion** (sediment in the river grinding against the bed and banks), and **attrition** (rocks colliding and breaking into smaller pieces). Over time, the valley is cut **deeply** into a V-shape. **Weathering** and **mass movement** (e.g., rockfalls) on the steep valley sides also contribute to the valley's shape.

### Question 10
**(a)** First step in a geographical fieldwork investigation: [1]
- **Answer:** **Identify the aim/hypothesis**
**(b)** Two data collection methods for a river discharge investigation: [2]
- **Method 1:** **Measuring velocity** using a flow meter or float method (timing an object over a known distance).
- **Method 2:** **Measuring cross-sectional area** using a tape measure (width) and a metre rule/depth gauge (depth at regular intervals).
**(c)** Importance of processing and presenting data before analysing it: [2]
- **Answer:** Processing and presenting data (e.g., in tables, graphs, or charts) helps to **organise raw data** in a clear and systematic way. This makes it easier to **identify patterns, trends, and anomalies** in the data. Without processing and presentation, it would be difficult to draw **valid conclusions** from raw numbers alone.
**(d)** Mean velocity calculation: [2]
- **Working:** (0.5 + 0.8 + 1.2 + 0.9 + 0.6) / 5 = 4.0 / 5 = **0.8 m/s**
- **Answer:** **0.8 m/s**
