The complete worked solution.
Every step explained - no skipped algebra.
Earth's axial tilt of about 23.5° causes different hemispheres to receive varying amounts of sunlight throughout the year. This uneven distribution of solar energy results in the progression of seasons, where one hemisphere experiences summer when tilted toward the Sun, while the other experiences winter. The tilt also leads to changes in the length of daylight and angle of sunlight impacting climate and ecosystems.
Final Answer: Option B - Seasons
