Exploring the Changes in Day Length from Summer to Winter

The video explores why the length of day changes from summer to winter. It explains Earth's structure, including the equator and hemispheres, and how Earth's rotation on its axis causes day and night. The Earth's tilt at 23.3 degrees affects the amount of sunlight each hemisphere receives, leading to longer days in summer and shorter days in winter. The video concludes with questions for further research on day length changes in the Southern Hemisphere and during fall and spring.
