By speed · Order from slowest to fastest.

1. The creep of a mountain glacier 175320 mm/year

   Glaciers flow downhill under their own weight like very slow rivers of ice, grinding valleys as they go.

2. A giant tortoise 500 m/h

   Giant tortoises can live over 150 years, ambling through more than a century of slow, steady days.

3. A duck paddling on water 1.6 km/h

   Ducks have no nerves or blood vessels in their feet, so they can paddle in icy water without feeling the cold.

4. A cheetah at full sprint 120 km/h

   A cheetah can go from a standstill to highway speed faster than most sports cars, but only for a few seconds.

5. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.

6. The motorcycle land-speed record 640 km/h

   Streamlined record bikes look like rockets on wheels, with the rider lying flat inside a sealed shell.
