17 Earth Trivia Facts For Earth Day

April 22nd is Earth Day, so you might be looking to celebrate the Earth with some trivia. Or, more realistically, you’ve got a trivia game coming up or something and if it’s going to be thematic there’s a non-zero chance an Earth-related trivia question will rear its head and you want to be prepared. Maybe you just like knowing facts so you can flex on people with Earth trivia facts.


Earth Trivia Facts

1. You’ve probably heard that the Earth, if shrunk to the size of a billiard ball, would be smoother. That’s not really true based on how the World Pool-Billiard Association defines smoothness and because Mount Everest and the Mariana Trench push the Earth a bit outside the billiard ball range. The Earth would, however, be rounder than a billiard ball. A good chunk of Earth (IE the not-Mount-Everest parts) would be smoother. 

2. The Earth is not a perfect sphere. 

3. Also, thanks to the gravitational pull of the Sun, Moon, and other celestial bodies, the Earth’s shape changes over time. 

4. Earth technically has a second moon named Kamo’oalewa. It’s more accurately a quasi-moon, and was probably part of our Moon (the one you see in the sky) at some point. 

5. Our Moon isn’t going to have to contest Kamo’oalewa for all that long since it’ll get flung into space outside of Earth’s gravitational range in like 300 years.

This is Kamo’oalewa’s orbit, by the way.

6. Speaking of gravity, Earth’s gravitational pull affects objects 13 million miles away. That’s more than 80 times the distance between the Earth and the Moon. 

7. Earth is 4.5 billion years old.

8. Because the Earth is not a perfect sphere (and because relative distances between you, the Sun, and the Moon exist), you’d actually weigh a little bit less on the equator than you would on the North or South Pole. The change is like 0.5% of your weight though, so it’s not worth factoring into any kind of diet or exercise regimen you might have. 

9. Earth is spinning at around 1,000 miles per hour. Try using that next time you get stopped for speeding. 

10. That’s not all, the Earth is also orbiting the Sun at like 67,000 miles per hour. Definitely try this one on your next ticket. 

11. Factoring in the movement of the Solar System around our galaxy, the Earth is actually moving through the cosmos in a kind of corkscrew shape. 

12. In between the next 200 and 300 million years, all the continents will merge again into one big supercontinent. 

13. At random intervals the Earth’s magnetic poles can just reverse themselves, a process that takes somewhere between 2,000 and 12,000 years. 

14. Only like 1.2% of Earth’s water is actually drinkable. 

15. Speaking of water, we’re not very good at conserving or distributing it. By 2050 two-thirds of the Earth’s population will be affected by severe water shortage if things don’t change—and it will be largely poorer populations that face the brunt of it. 

16. If you have one of those reusable cloth grocery bags you’d have to use it 7,100 times before it became equal to a disposable bag. 

17. Like 100 companies are responsible for 70% of global emissions. Yaaaaay.
