Earth's Seasons and Solstices

The video explains the Earth's revolution and its impact on seasons, focusing on solstices and equinoxes. It describes how the Earth's tilt and position relative to the sun cause different seasons in the northern and southern hemispheres. The summer solstice occurs on June 21st, with the sun over the Tropic of Cancer, while the winter solstice is on December 22nd, with the sun over the Tropic of Capricorn. Equinoxes occur when the sun is directly over the equator, leading to spring and autumn seasons. The video concludes with a diagram illustrating these concepts.
