Bedtime Facts (67/365)
The deepest part of the Atlantic Ocean is the Puerto Rico Trench off the coast of Puerto Rico

The deepest point of the Puerto Rico Trench is 8,648 metres. The trench exists because it is at the border of two tectonic plates: the North American plate and the Caribbean plate. The North American plate is moving towards the west and the Caribbean plate is moving towards the east. The North American plate is partly pushed under sideways be the Caribbian plate.

There is a risk of earthquakes in the trench and thus tsunamis. A tsunami is caused by a sudden downward shift by a piece of the sea bottom resulting in a tall column of water suddenly moving downwards. The west of Puerto Rico was hit by a tsunami caused by a major earthquake in 1918. The trench is capable of producing earthquakes of a magnitude over 8.0.
I wonder if it is more difficult to swim in a pole of water with a steeper floor.
It is quite interesting, if we put it in perspective, it measures almost the same as Everest, it is about 8800 meters high
That deep as hell, the deepest dive I achieved was 46 meters around 133 ft lol and we had to do a lot of stops for decompression and eliminate nitrogen in the blood, luckily I never saw anyone suffer from decomp sickness, but I heard some funny stories and some very bad one. cool geo-fact.
So cool that you deep sea dove. Where did you do it?
You dive? Well, that's interesting. How long does it take to ascend from 46 m safely?
I was about 19 years old and I have not gone back to diving about 12 years ago, if I remember well we were only about 3 or 4 minutes at that depth, we did not use any special mixture, we made stops one at 15 meters around 50 fts from around 6 min and another one 5 meters around 15 fts 3 or 4 min, we made another about 2 meters but that I don't remember well how much was maybe the instructor was ultraconservative.
I still have the tables to calculate those things.
Dobtge tectonic plates move? And cause deep holes in the earth? I am not that much aware about geography, keep sharing such posts, thankyou
Yes, tectonic plates move. They are moved by the circulation of lava in the Earth's mantle. The movement of tectonic plates causes the formation of mountain ranges, subduction faults and rift valleys among other things.
Marrku not talking to me anymore, seems I'm just annoying, I'm sorry :(
Don't worry. I don't reply to every one of your comments but that doesn't mean I have stopped talking to you.
Tsunami is not something to witness. Natural disasters are heartbreakers.
Great informative and geographic article.....
Thanks for giving us such great news.....@markkujantunen
Geography is a fascinating subject! And any subject that you can combine with coloured charts deserves to be liked!
