Earth's Movements and Their Effects on Seasons and Eclipses

The video explains Earth's rotation and revolution, causing day and night, and how its tilt leads to seasons. It covers solstices and equinoxes, solar and lunar eclipses, and the phases of the Moon. The video also discusses tides, including spring and neap tides, influenced by the Moon's gravitational pull.
