Topic 4
Earth Geometry
This topic applies the concept of Earth Geometry using latitudes and longitudes to solve real-life problems in navigation, aviation, and time zones. Learners will identify great circles (equator, meridians) and small circles (latitudes), locate points using coordinates, calculate differences in latitudes and longitudes, and compute distances along parallels and meridians in kilometres and nautical miles. They will find the shortest distance (great circle route) between two points on Earth's surface and calculate time differences and speed in knots. This practical topic links mathematics to geography and global systems, as assessed in ECZ examinations.
