The natural geography of a region. such as mountains or hills affect climates the mountains and hills would block winds and might create a valley that floods during heavy rains
It affects the climate by the positioning of the place. Say, if you were in the high mountains, it would be cold, right? And if you were in a flat plane, there would not be a way to shield you from the sun, so it would be hot there. It all depends on where you are, what time of day, and whatnot. Good luck!
