What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Here's me hoping the next cataclysm drains the oceans by a few hundred feet so we can establish New Old Zealand 🇳🇿

If submerged land can be called continents, where's the line between what is and isn't a continent?

[–] [email protected] 37 points 1 month ago

I think the reason Zealandia is called a "submerged continent" is because it is made of continental crust rather than oceanic crust.

But IMO the best geologic definition of continents is by tectonic plates, which mostly matches up with the cultural definitions of the continents.

For the major continents, we have these plates:

  • North American
  • South American
  • Eurasian
  • African
  • Australian
  • Antarctic

There are several smaller plates too, like the Caribbean, Indian, and Arabian plates. IMO, we should consider these independent continents.

There is also a dedicated Pacific plate. The ring of fire is the border of this plate.

New Zealand / Zealandia is on the ring of fire. Half on the Australian plate, half on the Pacific plate. You can actually see the border of the two plates when you look at the topographical map of Zealandia.

Oceanic crust is heavier, denser, and composed of different rocks than continental crust.

[–] [email protected] 10 points 1 month ago

It's just this, just simple geology.

The water level is actually irrelevant.

[–] [email protected] 15 points 1 month ago (1 children)

The OP states it was part of Gondwana, maybe that's what makes it different.

If you click through to the microcontinent link that seems to support the idea of microcontinents being pieces broken off a bigger one. But with everything coming from Gondwana then that means all the existing ones are fragments, and the only reason other fragments aren't considered continents is size (e.g. Madigascar).

Zealandia seems to be the Pluto of continents. Too small to be a continent but much larger than the largest microcontinent.

It's why there are a lot of cool dinosaurs found only in New Zealand btw

[–] [email protected] 20 points 1 month ago (5 children)

I live in New Zealand and haven't found any dinosaurs. I think they all died.

[–] [email protected] 10 points 1 month ago (1 children)

Did you check the other island? There's lots man

[–] [email protected] 5 points 1 month ago

I didn't! But I'll be sure to check the other ones next time I visit.

[–] [email protected] 5 points 1 month ago* (last edited 1 month ago) (1 children)

Nope, they're all around you and me and everyone else. They just evolved into things that (usually) have wings. In terms of phylogeny, they're dinosaurs.

[–] [email protected] 4 points 1 month ago

Well, maybe in theory. NZ has many unique birds not found anywhere else, but they are generally threatened or endangered. If you want to see them in the wild, generally you have to go to a very specific location.

If I look outside, almost certainly all I'll see are European dinosaurs.

So maybe I should correct my statement to say they almost all died out.

[–] [email protected] 3 points 1 month ago

You should double check just to make sure.

Geographical continents and geological continents aren't quite the same thing.

[–] [email protected] 3 points 1 month ago

That Civilization 6 uses geological continents when the 'continent' key word is used where every other game in the series uses geographical continents for that key word still bugs me.

[–] [email protected] 8 points 1 month ago (1 children)

That's a debate that transcends culture. Some cultures say there are seven, some say six, and yet others say five.

[–] [email protected] 6 points 1 month ago* (last edited 1 month ago) (1 children)

Seven is wrong no matter your definition of continent, unless you count New Zealand or "because racism."

Depending on your definition there are between four and nine continents, but the definition that includes Europe to make a total of seven necessitates India being its own continent without racism being the primary reason why Europe is a continent and India is not.

(Also if it transcended culture it wouldn't depend on culture for the answer)

(Also some people do say there are seven, because India is a continent with a land barrier and a tectonic plate and Europe is not)

[–] [email protected] 4 points 1 month ago (1 children)

Isn't all of Asia and Europe and Africa connected? I count 4.

[–] [email protected] 7 points 1 month ago

And that's valid, if your definition is just continuous land masses. However, some definitions incorporate ideas of notable narrowings such as the African and Central American connections and continental plates, or even projected drift.

For example, some day the Americas and Africa/Eurasia will separate from continental drift. Some even argue the Americas already are separated thanks to the Panana Canal, humans just hurried the process along.

So NZ is technically a mountaintop. Cool!

[–] [email protected] 58 points 1 month ago (2 children)

All land above water is a mountain top, at a certain scale.

[–] [email protected] 6 points 1 month ago (1 children)

And all continents are islands at a certain scale.

Mannnnnn, I wanna live on a billion year old, largely submerged continent. Shit looks dope af. And they seemed to kind win at Pandemic. Great share, thanks!

[–] [email protected] 8 points 1 month ago (6 children)

Just give it a few years. The continent you are currently on will be largely submerged soon enough.

All this time we've been keeping our true power hidden.

Also, if you mention Zealandia in New Zealand, people will look at you blankly and say "The bird sanctuary?"

[–] [email protected] 12 points 1 month ago

With rising sea levels it might end up as No Zealand

[–] [email protected] 9 points 1 month ago* (last edited 1 month ago) (1 children)

Isn't it called Oceania? Or are they different?

[–] [email protected] 14 points 1 month ago (1 children)

Oceania tends to refer to the region, including both Australia, New Zealand, Melanesia, Micronesia, and the many small island nations.

Sometimes, we are "collectivly" treated as a continent, despite being almost all island nations with no land boarders.

Well we don’t call you landiania

Try pointing to New Zealand on a map. I dare you

I mean it's next to Australia, pretty easy to spot ngl

That's actually Tasmania.

I believe Atlas Pro did a video on it one time. I'll go check.

wtf it looks like a fat New Zealand. is there an even slimmer version inside NZ?

[–] [email protected] 3 points 1 month ago

Excellent!

Any undiscovered cave entrances from the surfaced part?
