Source idea used to generate this video.

Create a 60-second educational explainer video titled: “Why Do We Have Seasons? — Earth’s Tilt, Not Distance from the Sun.” Audience: School students and competitive-exam learners. Style: Clear, modern, visually engaging educational animation. Use scientifically accurate diagrams, smooth animation, minimal on-screen text, clear labels and arrows where necessary. The visuals should explain the concept rather than merely decorate the narration. Narration: “Why do we have seasons? Many people think summer happens when Earth is closer to the Sun and winter when it is farther away. But that is not the main reason. Earth’s axis is tilted by about 23.5 degrees. As Earth revolves around the Sun, this tilted axis keeps approximately the same orientation in space. When the Northern Hemisphere is tilted toward the Sun, sunlight strikes it more directly and the days are longer. It receives more solar energy, producing summer. About six months later, the Northern Hemisphere is tilted away from the Sun. Sunlight strikes at a lower angle and the days are shorter, producing winter. At the same time, the Southern Hemisphere experiences the opposite season. So remember: seasons are mainly caused by Earth’s axial tilt combined with its revolution around the Sun—not by Earth’s distance from the Sun.” Important visual requirements: Clearly show the Sun, Earth’s orbit, the 23.5° tilted axis, Northern and Southern Hemispheres, direct versus lower-angle sunlight, and opposite seasons in the two hemispheres. Keep Earth’s axial tilt pointing in approximately the same direction throughout its orbit. Do not exaggerate Earth’s distance from the Sun as the cause of seasons. Ensure all scientific labels and diagrams are accurate. Output: Approximately 60 seconds, 16:9 landscape, professional educational-course quality, with synchronized narration, animation and concise on-screen labels.

Video narration

Why do we have seasons? Is summer hotter because Earth is closer to the Sun, and winter colder because it is farther away? Not mainly. Earth has an axial tilt of about 23.5 degrees. As Earth orbits the Sun, that axis keeps nearly the same direction in space. The key is this: the tilt changes how sunlight reaches each hemisphere. When the Northern Hemisphere tilts toward the Sun, sunlight is more direct and days are longer. More solar energy arrives, creating summer's hotter days. Six months later, it tilts away. Sunlight arrives at a lower angle, and days are shorter. Less energy arrives, so it is winter. At the same time, the Southern Hemisphere has summer-the opposite season-because it tilts toward the Sun. So, why the seasons? Earth's 23.5-degree tilt, combined with its revolution, changes sunlight angle and day length-not Earth's distance from the Sun.
