Question

why does the sun continually at the north pole for 6 months from spring equinox until fall equinox yet temperature never get very warm. explain this

Answer 1

This would be due to the sun angle never getting high and remaining shallow, thus the sun's rays never create much heating from atmospheric insolation. The majority of the sun's heat skips right off the different atmosphere layers, much like a rock skips off water if thrown from a shallow angle.
