Exploring the Causes of Seasonal Changes

The video explains the Earth's axis and its tilt, which causes variations in sunlight and seasons. It covers the spring equinox, where the Sun is over the equator, leading to equal day and night lengths. The summer solstice occurs when the Sun is over the Tropic of Cancer, resulting in the longest day in the Northern Hemisphere. The autumn equinox sees the Sun return to the equator, again equalizing day and night lengths. Finally, the winter solstice places the Sun over the Tropic of Capricorn, creating the shortest day in the Northern Hemisphere.
