Does spring and Fall exist at the poles?

Yes

Explanation:

The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The North pole always points the same way as the Earth revolves around the Sun.

Yes!

Explanation:

The Earth takes 365.24 days to orbit the sun, as we move around the Sun during the year, the amount of light each area of the planet receives varies in length. When the Earth’s axis points towards the Sun it is summer and when the Earth’s axis points away from the sun it is summer. So while the sun is rotating in between the times of the 6mths to get from one season to the other we have spring and autumn. The earth’s movement around the sun causes the seasons, but it does not affect the temperatures during the seasons. Fun fact many people believe that the temperature changes based on the sun, however during the summer months the earth is further away from the sun in July and closest to the sun in January in the winter months.
