Oceans

We know that the world ocean is bottomless and that the deepest trench in the world has almost 11 kilometers. We also know that the world ocean covers about 70 percent of our planet, making more than 2/3 of Earth’s surface unseen to us. But assume we obtained a way to drain oceans of our world, what would Earth’s exterior look like, exactly?

The world ocean covers more than 70 percent of the planet’s surface, and around 95 percent of the ocean is unexplored.
