What did North America look like 400 million years ago in the Silurian Period? It was the paleo-continent of Laurentia, long before it collided with Gondwana to form Pangea. In the Silurian, Laurentia was covered by shallow seas abundant with life, that died to form the beautiful limestone and dolomite cliffs we see at Niagara Falls. Let's learn a bit of earth history and the Latin and Greek etymologies that define these phenomena!

This is great! I'm a geology student and a latinist (I took three semesters of Latin in college!) so this is right up my alley! Having a background in classical languages is helpful in any science. But man, this was such an intersection of two of my biggest interests! Thank you, Luke!

@polyMATHY_Luke 11 месяцев назад

You explained this 10x better than any of my profs... and they even told me I shouldnt learn latin or ancient greek as it wouldnt have any use in modern science??? Greetings from Germany. I'll definitly learn latin and ancient greek after I finished learning spanish!

@polyMATHY_Luke 11 месяцев назад

Hallo, Ludwig! Thanks very kindly. Haha when I began my geology major in college, I was way ahead of everyone because I already knew Latin and Greek.

Omg I am obsessed with Continental Drift and the history of our tectonic plates and climate of our sweet little planet. Plus being a student in Greece, heavily focused on Ancient Greek and Latin studies, this is literally the best combo I could have expected from this channel. Awesome work!

@WolfgangSourdeau 10 месяцев назад

I would add a fews details : the organisms involved in the sedimentation of CaCO3 are called "Coccolithophores". Those microscopic algaes are part of the phytoplanktons and are an essential part of the carbon cycle : both as a CO2 sink and as the victims of the ocean being a sink itself. Ocean's capture of CO2 makes the ocean water more acidic, which tends to prevent Coccolithophores from forming their shells (coccoliths).

@polyMATHY_Luke 10 месяцев назад

Quite so! I'll cover coccolithophores in a future video.

It's crazy to think that for most of earth's 4.5 billion year history, complex multicellular organisms had only just arisen 500 million years ago. That means that for most of Earth's history, we were all just a bunch of bacteria (for around 3.5 billion years).

@polyMATHY_Luke 11 месяцев назад

Indeed! Isn’t that amazing? It really blows my mind. Its also crazy how little geological history is preserved from then.

@daciaromana2396 11 месяцев назад

@@polyMATHY_Luke Yep. That's probably because the old plates that held Earth's early geological history have dissolved under the Earth's mantle due to billions of years of plate shifting, except for a few places left on Earth like the Canadian Shield.

You missed Calcium. In latin it mean Lime. Original word, Calx.

@polyMATHY_Luke 11 месяцев назад

Not to be confused with the other calx, which is in the foot. In Italian, calcio is both calcium and soccer.

@@pierreabbat6157 you refer to CALCEUS, which is shoe or boot. Side note, Caligula carries this name, but it's diminutive, Little Boots.

@jeffreyschweitzer8289 11 месяцев назад

OK I know this is picky, but saying “this is when bony fishes first appeared” and showing a shark….?

@polyMATHY_Luke 11 месяцев назад

The shark is pursuing a school of fish, and the first sharks evolved in the Silurian too. They didn’t look quite like modern sharks; something like that evolved in the Devonian. These are just modern analogues, of course; they’re meant to be evocative of what things might have looked like back then.

@gabor6259 11 месяцев назад

5:08 How do ferrous rocks tell you where they were formed? The magnetic field of the Earth constantly changes, so how do you dicide between "this rock formed over there" and "the magnetic field was oriented this way at the time"?

@markvoelker6620 11 месяцев назад

There is a sunken continent, you know. It’s not Atlantis. It’s Zealand, of which only its peaks remain above water today, as the north and south islands of New Zealand. Also, there’s Doggerland, the sunken province of Europe which is now the North Sea. And about 5.6 million years ago, the Mediterranean dried up when the Strait of Gibraltar closed off, forming an unearthly basin resembling a gigantic version of the Dead Sea or Death Valley, where temperatures reached 180F and the atmospheric pressure was about 1.7 atm at the bottom of the basin about 3 miles below sea level. This is called the Messinian Salinity Crisis.

@mytube001 11 месяцев назад

The Med dried up and refilled several times during that time, not just once! Amazing to think that a small ocean can empty and refill like that.

@markvoelker6620 11 месяцев назад

@@mytube001 Yes! And imagine the waterfall at the Strait of Gibraltar when it refilled! A similar waterfall occurred at the Bosporus, when the Black Sea filled.

@iberius9937 11 месяцев назад

Why would a prehistoric period be named after a British Celtic tribe?

@polyMATHY_Luke 11 месяцев назад

Ah great question, perhaps I should have elaborated on that. An early geologist found rocks in Wales corresponding to the time period when it was identified.

@mytube001 11 месяцев назад

There's another! The Ordovician is also named after a Celtic tribe. And the Devonian and the Cambrian are names based on Celtic areas.

No, “looked like” does not imply identity of appearance, but similarity. “What did America look like then? Like Caribbean or Indonesian islands today.”
