Summer: What Causes Summer?

The video explains why summer is the warmest season and why days are longer. It attributes these phenomena to Earth's tilt and orbit around the Sun. The Earth's axis remains tilted in the same direction as it revolves around the Sun, causing the Northern Hemisphere to receive more sunlight during summer. This results in warmer temperatures and longer days. The video also highlights the specific dates marking the beginning and end of summer.
