If Salt Disappeared From the Ocean

Posted on 22 October 2019

The oceans make up 71 percent of the surface of the Earth, and they account for 97 percent of all of Earth’s water. So, as such huge parts of the natural world, what would happen if they lost all their salt? 

It wouldn’t be an ideal situation, that’s for sure! Salt actually plays an important part in keeping the world in balance. If every bit of salt was removed from the ocean, it would take out 45 million billion billion tonnes of salt. That actually means a big reduction in the weight of the ocean, which could generate earthquakes and volcanoes.  

Oceans are also home to lots of different marine species, like fish and algae. All of these would die because they wouldn’t be able to survive without their habitat. Algae play a very important role in supplying Earth with oxygen. If lots of algae died, oxygen levels would drop and carbon dioxide would rise, making the concentration of greenhouse gases much worse. This means the Earth would become very hot! 

Lots of other phenomenal weather patterns would take place, and it would make it near impossible for anything to survive on Earth.
