Actually, we once touched, then the Gulf of Mexico formed and separated us.


Cool, I didn't know that, thanks

I think looking into the past to see how we got to today is way more interesting.


I always wondered what the earth would look like in 10,000,000, 100,000,000, 1,000,000,000 years.

Yeah, we started to "drift" apart in the Jurassic. that's how old the Gulf of Mexico is. It started off as a shallow sea where a whole lot of evaporation occurred so it was super salty. Kind of like the Red Sea/Dead Sea now. All that salt later turned into rock and made the salt domes that Louisiana has today!

That's really easy to predict now that we've figured out plate tectonics and can trace tons and tons of feedback cycles across different studies like oceanography, climatology, ecology, geography, etc.

I don't know if there's a field of study dedicated to that though.
