20 QUESTIONS · 5 SYSTEMS · ABOUT 10 MINUTES

The ground moves about as fast as your fingernails grow.

Plates drift, rivers carve, ice grinds, and climate decides what grows where. Twenty questions on how the planet works, each explained, plus a game where you name a climate from its chart. No sign-up, nothing saved.

Name the climate from its chart

Geographers read climates from two lines: monthly temperature and monthly rainfall. Look at the shape across the year, then pick the climate type.

What this physical geography quiz covers, in short

Twenty multiple-choice questions on the natural systems that shape the planet, four in each of five areas: plate tectonics, weather and climate, water and ice, landforms, and ecosystems.

The climate charts use rounded long-term averages for real cities, which are named after you answer. The quiz is our own and not normed, so treat your score as a snapshot.

50 yearsfrom "absurd" to acceptedAlfred Wegener proposed drifting continents in 1912 and was widely dismissed. Seafloor evidence in the 1960s proved the plates move.1,2
1884Climates classified. Wladimir Köppen grouped climates by temperature and rainfall patterns tied to vegetation, the basis of the charts above.3
1912Continental drift. Wegener pointed to matching coastlines and fossils across oceans, but couldn't explain what moved the continents.1
1958The Keeling curve. Charles Keeling began measuring atmospheric CO₂ on Mauna Loa, recording its steady rise ever since.
1962Seafloor spreading. Harry Hess proposed new crust forms at mid-ocean ridges, supplying the mechanism Wegener lacked.2
