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.

Zealandia shall rise again!

With rising sea levels it might end up as No Zealand

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

Friesland is a province, smh

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

[–] Ultraviolet@lemmy.world 11 points 23 hours ago (1 children)

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

[–] VindictiveJudge@lemmy.world 1 points 19 hours 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.

[–] cbarrick@lemmy.world 35 points 1 day 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.

[–] youngalfred@lemm.ee 19 points 1 day ago (1 children)

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

[–] deadbeef79000@lemmy.nz 8 points 1 day ago

It's just this, just simple geology.

The water level is actually irrelevant.

[–] Dave@lemmy.nz 15 points 1 day 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

[–] Dave@lemmy.nz 19 points 1 day ago (5 children)

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

[–] FlyingSquid@lemmy.world 5 points 1 day ago* (last edited 1 day 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.

[–] Dave@lemmy.nz 4 points 19 hours 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.

[–] delirious_owl@discuss.online 10 points 1 day ago (1 children)

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

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

So NZ is technically a mountaintop. Cool!

[–] iAmTheTot@sh.itjust.works 57 points 1 day ago (2 children)

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

[–] FlyingSquid@lemmy.world 6 points 1 day ago (1 children)

And all continents are islands at a certain scale.

Slightly off topic, but this film can be enjoyed as:

[–] PlasticExistence@lemmy.world 2 points 1 day ago (1 children)

Oh, yes. That's how I originally saw it.

[–] FlyingSquid@lemmy.world 2 points 1 day ago

I originally saw the unriffed version and I still really like it. It sucks that Universal executives made them chop down the movie to shorter than the length of a TV episode (along with all the other stupid changes they forced). It makes it look like a much worse movie than it actually is. Not that it is a bad movie for MST3K, just that it was made unnecessarily much worse than it actually was, which was about what you could expect for "good" 1950s sci-fi.

[–] pyre@lemmy.world 4 points 1 day ago

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

[–] JusticeForPorygon@lemmy.world 9 points 1 day ago* (last edited 1 day ago) (1 children)

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

[–] Goodie@lemmy.world 13 points 1 day 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.

[–] captainlezbian@lemmy.world 3 points 1 day ago

Well we don’t call you landiania

[–] DaMonsterKnees@lemmy.world 15 points 1 day ago (1 children)

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!

[–] SatyrSack@lemmy.one 8 points 1 day 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?"

[–] owatnext@lemmy.world 7 points 1 day ago (3 children)

Wait until you hear about Doggerland.
