Every step explained - no skipped algebra.
Earth's axis is tilted at an angle of approximately 23.5° relative to the plane of its orbit around the Sun, known as the ecliptic plane. This axial tilt causes sunlight to strike parts of the Earth more directly at different times in its orbit, influencing seasonal variations. Regions tilted toward the Sun experience warmer weather and longer daylight hours, while those tilted away experience colder weather and shorter days.
Final Answer: Option B - 23.5°
