Solstices and Equinoxes in Astronomy

The video tutorial explains the differences between equinoxes and solstices. Equinoxes occur twice a year, during the autumnal and vernal equinoxes, when both hemispheres receive equal sunlight. Solstices occur when one hemisphere is tilted towards or away from the Sun, resulting in different sunlight amounts. The winter solstice marks the shortest day, while the summer solstice marks the longest day. The video also covers the impact of Earth's tilt on seasons and provides a Q&A session to reinforce understanding.
