I am a climate scientist and geologist and think that climate, geology, and geography are incredibly interesting fields that people deserve to know more about. If you have any questions that you’ve sat with for a while, are just curious, want to know more about future or past scenarios, or even have worldbuilding questions, feel free to ask!
Imagine a parking lot and a grocery store. Cars can come in and out, there's spaces for each little car, and it's purpose is to hold cars. The acid intermediary is that parking lot. The metal attractor is that grocery store. Cars are electrons. When there's lots of empty spaces it's easy for cars to pull in, so as long as the connecting road is open you can fill up the parking lots, when it's full the opposite is easier. The parking lot itself doesn't change no matter how many cars are in parking spots, so cars can come and go freely as long as the connecting roads are open.
