The video explains the differences between solstices and equinoxes, which are related to Earth's tilt and its orbit around the sun. Solstices occur when the sun's path is farthest from the equator, marking the longest and shortest days of the year. Equinoxes occur when the sun is directly over the equator, resulting in equal day and night lengths. The video also discusses how these events differ between the Northern and Southern Hemispheres.
