How can we be so sure that the Marianas Trench is the deepest place on Earth when much of the ocean hasn’t been explored yet?
In: Geology
The extent to which the oceans are unexplored is often misleadingly exaggerated. We know the topology of the oceans, they’ve just not been mapped at particularly high resolution, and of course most of it won’t have been physically visited. That doesn’t mean we have absolutely no idea what’s there though.
