Sure—here’s a simple sketch (not to scale):
Two sides of Earth’s orbit — the tilt stays the same

SUMMER WINTER
Earth is like a spinning, slightly leaning ball. As it travels around the Sun, it keeps leaning in the same direction.
- Toward the Sun: sunlight hits your half more directly, and days are longer. More warming adds up → summer.
- Away from the Sun: sunlight is more slanted, and days are shorter. Less warming → winter.
So seasons are caused mainly by Earth’s tilt, not by Earth being much closer to or farther from the Sun. And when one half of Earth has summer, the other half has winter!
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
