How is the earth's rotation axis oriented relative to the revolution orbit?
A)It changes with time so that it is perpendicular in June and December.
B)It is fixed and always points toward the North Star regardless of season.
C)It varies somewhat randomly over small angles,less than 23.5 degrees.
D)We don't really know how much it varies because we have not been able to make observations from space for more than about 60 years.

The Earth's rotation axis is fixed and points towards the North Star (Polaris) regardless of the season. This axis of rotation is inclined at an angle of approximately 23.5 degrees to the plane of the Earth's orbit around the sun. Hence, it is always oriented in the same direction relative to the Earth's revolution orbit.
