How does the geography of different regions affect climates

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!
