The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.Connected to continents moving aka breaking and the magnetic north movements. Reminder: [ link to www.businessinsider.com (secure)] Every second, millions of emails, clicks, and searches happen via the world wide web with such fluidity that the internet seems almost omnipresent. As such, people often mistakenly assume that internet traffic happens by air — our mobile devices, after all, aren't wired to anything.
But satellites carry less than 1% of human interactions, and in some ways the truth is far more impressive than messages sent by tower signal.
The internet — arguably the most important resource in the modern world — is very tangible and fairly vulnerable. It exists in large part under our feet, by way of an intricate system of rope-thin underwater and underground cables hooked to giant data storage units so powerful, they're capable of recalling any piece of information at a moment's notice.
To get the internet to what it is today, humans have slowly laid over 300 underwater cables that run a total of 550,000 miles.
About 97% of all intercontinental data is transferred through these cables, according to the Asia-Pacific Economic Cooperation forum.
The first transcontinental cable was laid down in 1858, and ran from Ireland to Newfoundland.
