Earth's Axial Tilt and Seasons

The video explains how Earth's rotation, orbit, and axial tilt cause seasonal changes. It covers the role of the Tropic of Cancer and Capricorn, equinoxes, and solstices in determining seasons. The impact of these factors on climate and ocean currents is also discussed, highlighting the interconnectedness of Earth's systems.
