How Earth’s Tilt and Orbit Cause the Four Seasons - Explained Visually #301628 (License: Personal Use)

The diagram illustrates Earth’s elliptical orbit around the Sun, highlighting the four critical astronomical events that define seasons: the Vernal and Autumnal Equinoxes (equal day/night) and the Summer and Winter Solstices (longest and shortest days). Each Earth position is shown with its axial tilt (23.5°), demonstrating how hemispheric exposure to sunlight shifts throughout the year. Additional insets provide top-down orbital views and globe perspectives for deeper comprehension.

Used in K-12 science curricula, educational websites, and astronomy resources to teach seasonal mechanics; matches user intent for visual learning, homework help, or teacher lesson planning.
