Rivers of the World
From the Nile to the Amazon — the great rivers that shaped where we live.
Which river is traditionally considered the longest in the world?
Everyone knows Paris and Tokyo. This quiz is about the capitals that catch people out — the purpose-built cities, the compromises and the ones that quietly moved. Each answer comes with the story behind it.
Naming capital cities sounds like pure memory work, but the reasons behind them are half the fun. Some capitals are simply the largest city; others were chosen precisely because they were not, to keep the peace between rival regions or to plant a new seat of power on neutral ground. This quiz runs through capitals from every continent, mixing the ones most people know with a few that regularly catch people out. The explanations add the context that makes each answer stick, so instead of drilling a flat list you come away with a mental map that actually holds together. It is a good warm-up for travel, pub quizzes, or simply filling gaps on your world map.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.
