What If Earth Was Half Land and Half Water?

 

Imagine Earth with an even 50/50 split between continents and oceans. Our planet covered half by land and half by water. When it comes to making life possible on a planet, water is an absolute must-have. That's why we look for alien life on worlds where liquid water could exist. When it comes to our own planet, 71% of its surface is covered by water.

Most of that is in our five oceans. Together, they form one global ocean Now, if you replaced nearly a quarter of our ocean water with land, how soon would Earth turn into just another lifeless rock in space Thanks to global warming, Earth’s sea levels are currently rising. But if you wanted to balance the planet’s land-to-water ratio, you’d see the sea levels absolutely plummet. And not just a few meters, but around 3 km (1.9 mi). Earth would look very different. The regions around both the North and South poles would be completely dried out. And every continent on the planet would expand.
