Question 1: You are given a table showing the population of five different cities in the UK. Describe how you would present this data visually to compare the populations effectively.

Answer: A suitable visual presentation would be a bar chart with city names on the x-axis and population numbers on the y-axis. Bars should be proportional to the population values, allowing easy comparison between cities.

Question 2: Explain the difference between a line graph and a bar chart, and give an example of when each would be most appropriate in a geographical context.

Answer: A line graph shows trends over time or continuous data, with points connected by lines, making it suitable for illustrating changes in temperature or rainfall over months. A bar chart compares discrete categories, such as population sizes of different cities, with separate bars for each category.

Question 3: A climate data set shows average monthly rainfall figures for a city over a year. Describe how you would display this data to highlight seasonal variations.

Answer: A line graph plotting months on the x-axis and rainfall on the y-axis would clearly show peaks and troughs, illustrating seasonal variations in rainfall throughout the year.

Question 4: Sketch a pie chart to represent the percentage distribution of land use in a rural area, with categories such as agriculture, woodland, and settlements. Label the sections clearly.

Answer: A pie chart divided into three segments, each representing a land use category. Agriculture might occupy 50%, woodland 30%, and settlements 20%. Each segment should be proportionate to its percentage and labeled accordingly.

Question 5: Describe how a scatter graph can be used to investigate the relationship between two variables, such as rainfall and crop yield.

Answer: A scatter graph plots individual data points with one variable on the x-axis (e.g., rainfall) and the other on the y-axis (e.g., crop yield). It helps identify if a correlation exists, such as increasing crop yield with more rainfall.

Question 6: Draw a simple bar chart with four categories representing different transport modes (car, bus, cycling, walking) and their usage percentages. The space should be large enough to include labels and proportional bars.

Answer: A bar chart with categories on the x-axis and percentage on the y-axis. Each bar height corresponds to usage percentage, with labels underneath each bar for clarity. For example, car 40%, bus 25%, cycling 20%, walking 15%.

Question 7: Explain why it is important to choose the correct type of graph or chart when presenting geographical data.

Answer: Choosing the correct graph or chart ensures the data is presented clearly and accurately, making it easier to interpret. Different data types require different visual formats—for example, line graphs for trends, bar charts for comparisons, and pie charts for proportions.

Question 8: Given a set of data showing the population growth of a town over ten years, suggest an appropriate method of presentation and justify your choice.

Answer: A line graph would be appropriate because it can clearly display trends over time, showing whether the population is increasing, decreasing, or remaining stable throughout the ten-year period.

Question 9: You have data on the average temperature and rainfall for a coastal region. How would you present this data to compare the two variables and identify any seasonal patterns?

Answer: Using two line graphs side by side or a dual-axis line graph can compare temperature and rainfall over months, highlighting seasonal patterns and whether they correlate.

Question 10: Sketch a simple climate graph showing average temperature and rainfall over a year for a tropical region. The temperature should range between 25°C and 30°C, and rainfall should have peaks during certain months. Label axes and key features.

Answer: A dual-line graph with months on the x-axis. The temperature line should fluctuate between 25°C and 30°C, remaining relatively stable, while the rainfall line should show peaks during specific months, indicating the wet season. Axes should be labeled clearly, with a legend for temperature and rainfall.
