What would happen if all the worlds oceans disappeared?
If all the oceans disapeared then 97% of all water would vanish. Quickly all the water in rivers would drain to the ocean and dry up. Rain would essentially cease all over the world since there is not nearly enough fresh water to make this happen. Cloud cover would dissapear and all areas would dry up and become arid. I’d say the whole world eco systems would collapse with some areas surviving that are normally arid like deep deserts. It might even affect them since there would not even be water in the air anymore since so much disappeared.
