Basically sediment from the Appalachian region was deposited by ancient rivers and wind currents, with this sediment later being uplifted and then eroded to form the Rockies.
As a geologist who works in the Appalachians… They’re cool af.
Nothing is more surreal than being a geologist. Just today I was standing on a dirt road in the middle of farmers field. Looking at the ground is an innocuous little outcrop of boring looking rocks. But those rocks erupted at the bottom of a back arc basin off the coast of Laurentia, was buried by ocean sediment for ages, had an entire ISLAND of rock thrust onto it, and then buried 10s of kilometers deep. The history one rock can tell is amazing.
As a non-geologist living next to Lake Diefenbaker (the reservoir formed by damming the South Saskatchewan River), I also like geological history.
I have a standard reply for when I’m asked why we chose to move to this “treeless wasteland”. “I look out at the flat horizon and see how the glaciers planed the earth the way a woodworker flattens a board. I look around me at the river breaks and see how the meltwater from retreating glaciers carved the earth away into shapes that defy imagination.” I don’t know accurate any of that is, but it fits my mental model of what I was taught in high school.
(What we call the river breaks are twisted and braided networks of coulees, some with sides so steep as to require mountaineering equipment. Most still run with meltwater in the spring.)
I have started daydreaming of a career change to geology. There are just so many unanswered questions and its not like space or physics were these questions are tinyor super far away. You can just walk upto a geologic puzzle and hit it with a hammer.
That is not exactly true. My dad was a geology professor. About half his students ended up in oil and gas. The other half were employed as city planners, teachers, consulting geologists, and in , civil engineering firms, environmental services firms, mining and others.
Not sure if my username gave it away or not, but I’m really into applied mathematics. I’m a physics major right now, & while I don’t immediately see myself studying this in grad school, I think that the physics of Volcanism/Plate Tectonics is extremely fascinating. It certainly looks at the history of the world through a very different lens, but I wouldn’t write it off completely!! The physics of our Earth is a beautiful, beautiful thing. :)
I’m by the river Meuse in Wallonie, which still cuts through the Ardennes, another end of same old mountain range as the Appalachians, continuously eroding while mountains uplifted (just as Indus and Brahmaputra cut through Himalayas now), before the Atlantic ocean existed. Makes you think about time, pity schools don’t teach this stuff.
They probably sent out thousands of requests and only heard back from those places. Let’s be honest: This’d be a great response rate, depending on the study.
Have y’all tried her diet? I don’t know if it’s backed by science or not, but you can eat just about anything on it. My buddy Joe tried it, it made Joe lean.
Block, report or read the rules and ask the moderators. You’re wasting your own time and everyone else’s, I found this an enjoyable meme and so did many others.
I feel like blocking the user because I don’t think they’re post fits a community is a pretty fucking drastic action dude. Also I never blocked moderators of communities that I enjoy because the system with moderators and user blocks is kind of fucky on here. I don’t think is right to block a moderator.
Edit: cry harder babes it’s OK:( the scary man can’t hurt you from here
Nah, replication is enough, shows interest. This meme was stolen, thus it lives on as a vehicle. The intention here is to simply get people interested in the world around them. Not sure what the original goal was. This one just has a little more .jpg than the last. I’ve seen variants of this one, regardless. This is an old one.
