I grew up in very flat parts of the world and have always basically lived in flat parts of the world. Czestochowa (Poland) is the most hilly part of the world I've ever lived in, and aside from the big fortified church on a hill in the middle of town our neighbourhood was basically flat.. with no mountains in view in the distance or anything like that. For that you'd have to drive south for several hours.
I don't know if this is really "worldview", but whenever I hike out into the mountains, the first couple days seem sort of magical. It's like my brain is trying to understand the scope of what it's seeing, and it's like you're feeling that process of your brain trying to wrap itself around the scope of it all. The first time I was ever hiking by impressive looking mountain peaks was in Patagonia, and it just all felt so grand and majestic.. and parts just didn't look like they should have been real. Each time I visit pretty mountains, there is a bit less of that feeling.. but it's still there, and I hope it stays there forever
Other than that I can appreciate geography and climate affecting culture a bit better, after travelling around the world a bit. People's lives revolve around the sun and the seasons and in different places that can mean different things depending on in part weather patterns, which are in part influenced by geography.
I've also learned that people living and being familiar with a certain "biome" have a certain sort of knowledge of how to live in that reality and how to use it to their advantage. When you go to a different biome and geographic reality, that knowledge can change too.
