Question
The axis of earth’s rotation relative to orbital plane is tilted by:
Explanation
Earth's rotational axis tilts 23.5 degrees from perpendicular to orbital plane around Sun. This obliquity causes seasonal variation as hemispheres receive differing solar insolation through year. Tilt remains stable due to Moon, while precession slowly changes orientation over 26,000 years, fundamentally driving climate and solstices.
