If there are hot springs, are there cold springs? If so: how?
I understand hot springs. It's easy to conceive of warming, because warming is an active process and a byproduct of a lot of things. The earth makes a lot of heat inside itself. However, it seems like it'd be a lot harder to maintain a body of water at a consistent but below-ambient temperature, right?
But there are places called "Cold Springs", so are they really a thing? Or is it only relative to the *hot* ones?
If cold springs are a thing, how do they maintain that? Why don't they warm up to ambient? #science
