48 free English Channel trivia questions with answers — geography quiz, new questions added Sep 2026.
This English Channel trivia quiz covers the arm of the Atlantic that separates England from France and has shaped both countries' history for two thousand years. The easy questions cover the countries on each shore, the French name, the narrowest strait, the tunnel that runs beneath it and the busiest shipping lane in the world. From there the quiz moves through the history: Caesar's landings, the Vikings and Rollo's Normandy, the Armada, Trafalgar, Bleriot's flight, the Dover Patrol, Dunkirk, D-Day and the only piece of the Commonwealth the Germans occupied. The hard end covers the glacial megafloods that carved the Strait of Dover, Hurd's Deep, the tidal funnel that produces six-metre ranges in the Channel Islands, the shipping forecast areas, the first radar-controlled traffic separation scheme, the balloonists of 1785, the Gossamer Albatross, Captain Webb's 21-hour swim, Gertrude Ederle, the fastest verified crossing, PLUTO's pipelines and the amphibious cars that drove to Calais. Every answer was checked against the encyclopaedia entries on the English Channel and the Channel Tunnel before publishing, and the supporting sentence is stored with each question. Our British geography and Second World War quizzes are natural next stops.
