24. What does the term 'contour line' represent on a topographic map? — Lines of equal elevation above sea level

25. Which map projection is often used for small-scale maps of large areas like continents or the world, balancing distortions? — Robinson projection

26. Which type of map projection is best suited for accurately showing the relative sizes of countries on a world map, even though it distorts shape? — Gall-Peters projection
