Top 10 Longest Mountain Ranges Quiz — Rules & What Counts

The ten longest mountain ranges on land, and one question: do you know where each of them actually runs? Every range is a named card in the tray — drag it onto its ring on the map. Nothing to recall, only geography to get right.

The list is sneakier than it sounds. Everyone can point at the Andes and the Rockies; far fewer know that the world's second-longest chain wraps around southern Africa, or that one entry crosses Antarctica — which is drawn on this map specifically so you can place it.

How to play

• Drag each range card from the tray onto a ring — every ring sits on the range itself.
• Exact placement is the rule: each range only scores on its own circle, but the ten rings are continents apart, so the right neighborhood is all you need.
• Drops snap to the nearest ring within a generous radius; a sloppy drop fills an empty ring rather than bumping one you've placed.
• Nothing is graded until you press Confirm — rearrange as much as you like first.
• The timer counts up from zero, and give up grades what you've placed and reveals the rest.

What counts in this quiz

• The 10 longest mountain chains on land, ranked by length — from the Andes at roughly 7,000 km down to the Himalayas at roughly 2,300 km.
• Length is the only metric: the Himalayas hold every one of the world's tallest peaks yet barely make this list, because height wins you nothing here.
• The Southern Great Escarpment counts — the Drakensberg is its most famous stretch — following the conventional list of Earth's longest chains.
• The Transantarctic Mountains are a required answer, which is why Antarctica is visible on this map.

What's not included — and why

• Undersea ranges don't count — the mid-ocean ridge system is by far the longest mountain chain on Earth (~65,000 km), but this list is land only.
• The Alps don't make the cut: at roughly 1,200 km they're less than half the length of the tenth-place Himalayas.

Good to know

• The Andes span seven countries and hold the highest peaks outside Asia — plus the world's highest capital cities.
• The Urals are the classic dividing line between Europe and Asia — a single range with a foot on each continent.
• The Appalachians are older than the Atlantic Ocean, and the Scottish Highlands are geologically part of the same ancient chain, split apart when the ocean opened.
• The Great Dividing Range is the third-longest land chain on Earth, yet its highest point — Mount Kosciuszko — is barely 2,228 m.
