Explain a regional pattern with evidence
Start a geography task by identifying the place, scale and kind of evidence. A contour line connects equal elevations; closely spaced lines indicate a large height change over a short horizontal distance. A map scale converts the measured map distance into an actual distance, so convert centimeters to meters consistently. For climate, connect seasonal winds, relief and moisture rather than attaching one label to every location within a prefecture. Compare the Pacific side with areas sheltered by mountain ranges and ask which mechanism the question actually supplies. Population density requires population divided by area, while an aging share is a proportion of a population; neither is the same as a total count. When interpreting a regional survey, distinguish a documented observation from a proposed explanation. Kochi-related examples can support local familiarity, but preparation also needs the wider Japanese and world geography taught in junior high school. Avoid treating an undated local statistic as a permanent fact. Record the source year whenever a question depends on a changing number.
