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)

As a reminder, please do not discuss current struggle sessions in the mega. We want this to be a little oasis for all of us and the best way to do that is not to feed into existing conflict on the site.
Also, be sure to properly give content warnings and put sensitive subjects behind proper spoiler tags. It's for the mental health of not just your comrades, but yourself as well.
Here is a screenshot of where to find the spoiler button.

::: spoiler paranoia, dysphoria, transphobia, ableism, and genocide I'm extremely fucking scared right now. i had a nap earlier and there was a dream where my mom went into my room and found out (again) that I'm trans and was scolding me or whatever and i kept waking up and going back to sleep and thinking it was real, I went to sleep before that earlier thinking about what's happening in the USA and stuff and being horrified of the thought of a genocide happening. I'm so tired of my family too, all their transphobia is so tiring, and school too. I have to say nothing every time I'm called by my deadname instead of Sally and not say anything when people call me "sir" or "mr" or "young man" because if I do I'm in danger because of how fucking stupid Texas is. Brother back in March tried to literally gaslight me into thinking I'm not trans, saying "it's probably just an identity crisis" when I've identified as trans for 5 years now, he's the type that thinks you're "vulnerable" and can't decide for yourself if you're neurodivergent or something I think. I just want it to be 2027 or 2028 already so i can escape and be myself, why do I have to go through so much pain just to some day get to a point where I can hopefully be myself?
edit: i accidentally posted this suddenly and it scared tf out of me when i wasn't ready hopefully this is ok to post here though idk I'm an extremely paranoid person about everything
