For a couple of years and from time to time, a very specific type of article has gone viral: one that repeats that there is a group of researchers from the University of Derby has found a new (micro)continent in Davis Strait. That is, between Greenland and North America.
And yes, it sounds a little Martian. How could we have lost an entire continent in the 1,143 kilometers that that strait measures? It has its explanation
What the hell is a continent? The most intuitive answer is “a large area of land surrounded by water”; But the truth is that it only works in theory and, when we tackle the problem, everything gets complicated. Therefore, if the question is “how many continents are there in the world?”, the only logical answer is this: “it depends.”
What do you mean “it depends”? The reasons behind many of the divisions we handle are “purely historical and cultural.” In fact, as Miguel García explains“the educational systems of different countries establish different continental divisions”:
- In Anglo-Saxon countries, it is most common to say that there are seven continents (Europe, Africa, North America, South America, Asia, Antarctica and Oceania);
- On the other hand, in Romance language countries, the most common answer is that there are six continents (uniting the Americas into one);
- Six continents are also explained in the countries of the ex-Soviet orbit (although they keep America separate and what they unite is Europe and Asia).
There are more options, of course. For example, we could unite Asia, Africa and Europe on a single continent and, together with America, Australia and Antarctica, there would be four. By proxy, we could even remove Antarctica because, well, without its snow cover it would become an archipelago (whose largest island would be smaller than Australia).
It’s time to admit that continents do not exist. They are social constructs, like municipalities or provinces. Hence, as García explainsFrom a geological point of view, it can be concluded that continents do not constitute a scientific concept. In any case, we can talk about tectonic plates (and, although defining their number is also a hassle, we would not talk about less than 15).
So what are the Derby researchers talking about? Now it’s time to get into the matter: what researchers have used is something elsethe thickness of the Earth’s crust. In general, there are two types of Earth’s crust: continental (about 35 kilometers thick) and oceanic (between 8 and 10).
Of what they have realized is that as the tectonic plates between Canada and Greenland have shifted, the Earth’s crust has been reconfigured. The result has been a protocontinental (i.e. extremely thick) crust on what should be an oceanic crust.
And what is all this for? It must be admitted that, once we get the matter down, everything seems more boring. However, the finding is very interesting: we actually don’t know very well how tectonic dynamics work. We have very developed ideas and models, yes; But when it comes down to it, there are more questions than answers.
Being able to study in detail the formation of a protomicrocontinent is a unique opportunity to understand phenomena such as the one that is dividing Africa in two. And we have already seen that, unlike what we tend to believe, this has a real impact on daily life of millions of people.
