Question

what will happen if earth stops rotating on its axis

Answer 1

There are just so many things that we take for granted: our teeth, our neighbor’s WiFi password, and even the existence of life on Earth! The three things that I listed here are absolutely unrelated, but that’s not the point I’m trying to make. I’m trying to express how the smallest and most obvious things that happen every single moment all around us shouldn’t be taken for granted. If everything on this planet stopped moving suddenly, it could mean instant obliteration of life as we know it.

Answer 2

Then both rotation and revolution will be stopped causing much damage to ecology and ultimately end of the hostile environment and civilization .... The complete breakdown of its forces will make it transfer back to the Cold age or older than it ...
