1. The drift of a tectonic plate 21.9 mm/year

   Plates move about as fast as your fingernails grow, yet over millions of years they have rearranged whole continents.

2. The growth of human hair 175.3 mm/year

   Scalp hair grows roughly 1.25 centimetres a month, so a single strand reaching your shoulders is years old.

3. A yellowfin tuna 73 km/h

   Tuna are warm-blooded among mostly cold-blooded fish, letting their muscles fire faster for high-speed chases.

4. A Category 5 hurricane's winds 300 km/h

   A single mature hurricane can release more energy in a day than the world uses in electricity all year.

5. A peregrine falcon in a dive 410 km/h

   The peregrine is the fastest animal on Earth, diving so fast it has baffles in its nostrils to breathe.

6. A bullet from an AK-47 2.7K km/h

   The AK-47 is the most widely produced firearm in history, prized for working even when caked in mud and sand.
