why is it much colder in the poles if the sun is so far away anyway, shouldn’t it not make any difference?

And i guess the same question for deserts.

This seems to be a common misconception. Temperature of a certain part of earth is not significantly dependent on distance from the sun. The earth varies in its distance from the sun by more than its diameter just by the time of year IIRC. It’s about the angle. Each square unit of ground at the poles receives far less energy from the sun not only because of the oblique angle it hits at, but because there’s more atmosphere to absorb and scatter the sunlight first. (Not that the atmosphere there is thicker, but because the sun has to come in at a flat angle and interacts with more of it.)

Deserts are a little different because their main feature is dryness. But while climate can be a complex topic, suffice to say the hottest deserts are fairly close to the equator where the sunlight is more directly overhead, putting the most energy into a given area.
