Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Damn I didn't realize we dug into them tectonic plates.

They are separate tectonic plates, the two continents only crashed together relatively recently, the "columbian exchange" that saw wildlife mix between the continents. South America was near Africa at one point, North America more with Europe as I understand it.

I find it really cool that the Appalachian mountains used to be connected with what's now the Scottish Highlands, if memory serves correctly.

When I was on the Appalachian trail they had a placard that explained it and said it's also the oldest mountain range in the world, and used to be like 4x the size of the himalayans (which is the youngest.) Others have disputed that, but just internet randos with no sources, I trust the NPS placard.

So crazy to think about because they're so worn down at this point. Neat!

Hills near me (northern Scotland) were once magma chambers underneath volcanoes! That's how worn down they are. Wild to think about, and makes some lovely granite.

We did! The canal is tens of meters deep, while bedrock is typically not more than a few meters deep anywhere on earth (except where cover naturally collects in places like valleys).

They're also not on the same tectonic plate
