Which diagram best represents the relationship between the Earth and Sun that causes the changes in seasons on Earth?

The best diagram to represent the relationship between the Earth and the Sun that causes the changes in seasons is one that shows the Earth's axial tilt and its orbit around the Sun. This diagram would illustrate the Earth's tilt at approximately 23.5 degrees, demonstrating how different parts of the Earth receive varying amounts of sunlight throughout the year. As the Earth orbits the Sun, this tilt causes seasons to change, with summer occurring in the hemisphere tilted toward the Sun and winter in the hemisphere tilted away.
