What Would Happen If Land and Oceans Changed Places?

What if all the Earth’s land became ocean, and all the oceans became land? More than seventy percent of the Earth is covered with water, and that massive amount of it is one of the main reasons life exists on this planet. But if water and land were to swap places, the Earth would become a completely different place. How would it affect the climate? Would humans as a species even exist in a world so radically different from our own?

Let’s try to look at some of the more drastic changes that would happen if land was to become water and water was to replace land on mother Earth. For the sake of easy map drawing, let’s say that it was a direct one to one flip. Everywhere there’s land, there’s water, and vice versa. The Atlantic Ocean? The continent of Atlantica. The Great Lakes? The Great Islands.
