Happy Equinox! | Science for Kids

The video explains the concept of equinox, a time when day and night are of equal length, occurring twice a year. It describes Earth's movement around the sun and its axial tilt, which causes seasons. During equinoxes, the equator receives the most direct sunlight, leading to equal light distribution across the planet. The spring equinox marks the transition from winter to warmer days, while the autumn equinox signals the shift towards cooler weather.
