Our Amazing Planet: How Deep is Deep?

Posted on November 18, 2014 by Dr. Lynda

What can one of the creative minds behind the movies Titanic, Avatar and The Terminator series, teach us about the deep ocean? The answer demonstrates that innovators are often capable in leading us to new places in many directions!

James Cameron, whose name you might recognize from those Hollywood hits, designed a deep sea vessel and successfully dove seven miles deep to the deepest point in the Earth’s ocean: the Mariana Trench of the Pacific Ocean. 1

While that’s astounding enough… can you even begin to comprehend what seven miles deep is? That’s roughly 36,000 feet, or nearly 11,000 meters/11 kilometers! Keep in mind that that is another 4,000 feet deeper than Mount Everest is tall. Here’s what “deep ocean” means in terms that we can hold in our mind’s eye:

So now that we have an idea of the deepest deep on earth, let’s look at today’s featured infographic (or a webcomic, as it might be better categorized), found on the online comic site XKCD’s author Randall Munroe. Find the landmarks in the natural world nearest you, in your country. Fascinating when it’s laid out like this.

Be certain you give this time to load fully as it’s a large file, and take your time in viewing this: read some of his annotations… they’re pretty amusing as well as hard to believe!

Did you explore a bit? And find the funny little extras in the infographic that prove scientists can have great senses of humor?
