🌍 Earth's Revolution and Seasons
This quiz explores Earth's annual orbit around the Sun and how axial tilt creates seasonal changes across the planet. Learn about the 365-day revolution, solstices and equinoxes, and why the Northern and Southern Hemispheres experience opposite seasons. Discover how Earth's tilt angle affects temperature and daylight hours throughout the year. **What you'll learn:** - How Earth completes one full orbit around the Sun in 365 days - The role of axial tilt (23.5°) in creating seasonal temperature changes - The four key events: spring and autumn equinoxes, summer and winter solstices - Why opposite hemispheres have opposite seasons at the same time - How tilt angle affects daylight hours and solar radiation intensity
