    Small? The Appalachians today are the resting skeleton of a mountain range so tall and enduring that the mud and sand that washed off them piled miles high and formed the Catskill mountains. The Appalachians were so mighty that their garbage formed mountains

        Completely unrelated. North and south america wern’t attached when the appalachians were tall. The Andes are formed by an ocean plate (the Nazca plate) dragging as it is sucked under south america. They are tall, and still growing taller.

    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.

      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.

      They didn’t. The bone like structures inside of dinosaurs are called fossils, and they’re closer to rock than bone

      Dang I didn’t even notice that logical inconsistency until you pointed it out. It should say “The mountains aren’t just older than dinosaurs.”

      Of course you’re getting downvoted to hell because everyone either didn’t slow down to read it more carefully or can’t understand sarcasm.
