Fascinating! I knew a few of these, but it's always cool to learn about all the history that's tied into place names.

Finnish place names are largely related to geography, though the meanings may not be immediately obvious to modern speakers. But most can be explained.

My current town is named after the rapids that run through it (and have been the main source of energy for it even in pre-industrial times), and my hometown after the type of forest (and ground) that grows there, which is easy to travel in.
