Limestone is a common type of sedimentary rock which I find uncommonly interesting! It's mostly calcium carbonate, which is also what eggshells π₯, seashells π, and pearls π¦ͺ are made out of.
In places where it rains a lot, limestone erodes easily, which results in simply gorgeous landscapes such as:
HαΊ‘ Long Bay in Vietnam
Tsingy de Bemaraha National Park in Madagascar
The Li River in China
Additionally, the world's longest (Mammoth) and deepest (~~Veryovkina~~ Krubera is once again the world's deepest cave, thank you to SockOlm for pointing that out) cave systems are both found in limestone formations
Mammoth Cave in the United States
Veryovkina Cave in Georgia/Abkhazia/Russia (disputed territory)

Update on coming out to my friend. I haven't seen much of her in a few years but still counts. She's proud of me, glad I told her, and I got to tell someone else my name. (which she loves for me and I am riding that wave, holy hell I forgot how much I like having my name complimented). She's actually got a trans member of her extended family, which I didn't know about. So yea, very nice to get to talk with her about it a bit.
I still (kind of, complicated obviously) come out to my main irl friend. Don't know when that will happen though.
