Spheres representing all of Earth's water, Earth's liquid fresh water, and water in lakes and rivers

  1. Is it the fact that a sphere of “all the lakes and rivers worth of water” is like 1/10th the size of Lake Michigan? Something about this scale is not right. Or something about sphere volume is deceptive.

  2. Neil deGrasse Tyson explained the Earth's surface is smoother than a que ball by the production standards at scale. Pretty wild to think about but it helps me understand why such a seemingly small glob of water could cover the majority of the planet.

  3. This really doesn’t look right to me. Seems like the smallest sphere wouldn’t even fill the Great Lakes at the scale shown.

  4. It's about total volume and they're being compared. The details are suspect but when I imagine the total volume of surface water vs the total planet, this doesn't seem too far off.

  5. If you made an exactly to scale topographical globe (like some globes where the mountains and what not are raised up) the size of a billiard ball, it would be smoother than any billiard ball could possibly be manufactured. The difference between the highest point on earth (Everest) and the lowest (Mariana’s trench) is about 11 miles. Lay that out flat and you can walk that distance in a few hours easily.

  6. I also did some guesstimating and found that the diameter of the cube is roughly 1380 km which is approximately the distance from Washington DC to Jacksonville Fl.

  7. Its is, its mindbogling, the same as the fact that if you would shrink earth to a cue ball size, the earth would be smoother than the cue ball.

  8. I was all about that until I found out about how much it actually pollutes the ocean. It'll just kill off whatever remaining fish we have.

  9. I was thinking the same thing. I can’t comprehend the possibility of the smallest sphere filling all the great lakes, not to mention all of earth’s other freshwater lakes and rivers. Usually infographics are neat but this one does a bad job getting the message across.

  10. Volume in the smallest one (rivers and lakes) is around 93,000km³ (56km diameter), Lake Superior is 12,100km³.

  11. Cuz it's a 3D ball, pretty impossible to tell how big each ball really is, like is it 10 feet tall or 1000 stories tall. Not sure why they would make it like that.

  12. Shit the water in the aqueduct in CA that can’t be used because of a 3” fish that tree huggers think is endangered!

  13. The Michigan SC ruled today that 3M doesn't have to clean up PFAS from the water, so make that little drop littler.

  14. Another interesting fact: The combined volume of all water on earth hasn't changed in millions of years.

  15. So you're telling me that the water that covers most of the surface summed up would be just tiny drop next to the usa? I don't believe this

  16. I was really amazed when I saw this graphic. Previously I thought the amount of water was 10X that much. I do believe that this amount will change over time as they discover more underground pockets of water that will increase the total amount. But still this seems to be amazingly little water for our planet.

  17. Imma need dimensions of those spheres and a number for how much water that’s suppose to represent prior to sphere-ing it. Fake news

  18. Bro imagine how long it took to suck up all the water on earth and turn it into a ball? Respect to whoever made this diagram!

  19. false, we don't even know what's under a few miles of crust we gonna know how much water we have. all we have is guesses.

  20. One big mistake and then the Earth will fully turn into desert. Is it really possible for Earth to dry up just like how Mars suspected to be abundant of water before?

  21. Now I really also want to see how much of that water are in clouds, and in ice, and trapped in the ground.

  22. People overestimate how much water is on earth, likely cause they have little grasp on how depth is extremely minuscule compared to the incredible size of the earth.

  23. you know how when you spill a cup of water on a flat surface and it spreads out connecting to other drops of water that's basically whats happening with all the water on earth it spreads out and covers a large area

  24. For all the doubters here is another comparison… the largest sphere (if perched at sea level) is over TWICE as high as the International Space Station.

  25. I feel like this is a bad way to present it. If they want to show it in comparison to the rest of the earth, then that's fine. Though i would rather present the continents as another sphere, so that they can be compared instead.

  26. The first sphere is labeled as "All water on, in, and above the Earth" which clearly isn't true, as it isn't big enough to fill any of the oceans.

  27. It is though. It's a sphere of water. The oceans are just a few miles deep at their deepest, which is practically nothing at this scale. It's basically just a thin film of water covering the planet.

  28. This reminds me of the one about gold. If you took all the gold ever mined and melted it into a cube, it would fit under the Eiffel Tower. Which is again hard to believe given the millions of people with gold things, and the size of the industries created around it, but it’s true

  29. Something seems off with this, the worlds oceans can't be that shallow? Picture that you spread that sphere of water across all the earths oceans + the icecaps on both the poles? No way that can be all of earths water

  30. I've always pondered this dilemma; as humans breed in plague proportions across the globe (8 billion), and we are made of 70% water would this not have an impact?

  31. Keep in mind that you'd be able to see this massive water blob from Africa. It extends thousands of miles into space.

  32. Might not be 100% correct. That's probably how much water on the crust, but recent research suggest twice that much or more might exist under the crust and inside the earth mantle.

  33. I’m confused, what’s the difference between 2 and 3? Where is all this extra “liquid fresh water” of its not in the “lakes and rivers” I understand there’s a lot of fresh water in the ice caps, but that’s not liquid. I also understand there’s a lot of fresh water in the atmosphere, but again, that’s not really liquid
