The Earth is literally covered in water: It makes up over 70% of our surface, and without it our planet would be inhospitable. When it comes to our Earth’s oceans, the vast majority of their expanse remains unchartered and unexplored. In fact, we have more comprehensive maps of the moon’s surface than of the bottom of our ocean floors. While the ocean floor seems distant and irrelevant at times, the fact of the matter is that our ocean floors are home to a whole host of mysteries. not to mention thousands of volcanoes and shifting tectonic plates. By learning about the bottom of the ocean, scientists may one day be able to understand and adequately prepare for earthquakes and tsunamis that are caused by movement along the oceanic floor.
Despite covering 72 percent of Earth and supplying more than 70 percent of the world’s oxygen, there’s still a lot we don’t know about our planet’s life support system.
Here’s a brief guide to our exploration of the ocean:
