Answer 1

It’s not the same angle. Our orbit changes a bit every year. These changes follow a pattern. The sun it’s self has a pattern of increasing and decreasing output. Combine that with the earth isn’t a perfectly flat sphere. It has land masses of varying shapes and sizes. This all combines with even more factors to cause our varying weather.
