The water will cut into the sand below the hard object and it’s this part of the moving water that ultimately results in the waterfall. If you run this experiment long enough, you should be able to form your own little waterfall! WebFinally, computer simulations reported on in 2024 have suggested a closer origin for at least some water on our planet. The idea is that water could develop deep inside Earth's mantle and eventually escape via earthquakes. And so, while we can't say with certainty how water came to Earth, we can say we're fortunate it did.
