What location is 70 degrees west 90 degrees north on the globe?

Answer 1

"90 degrees north" is the definition of the north pole. And since all longitudes converge (meet, come together)

at the north pole, the longitude doesn't even matter ... they're all there at the same point.

Same thing at the south pole, which is "90 degrees south".

Answer 2

The location 70 degrees west and 90 degrees north is the North Pole. This point is at the northernmost point on Earth, where all lines of longitude converge.
