my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Sure! Here’s a simple picture of Earth at two points in its trip around the Sun:
NORTHERN HEMISPHERE: SUMMER NORTHERN HEMISPHERE: WINTER

June December
tilted toward the Sun tilted away from the Sun
Earth is tilted, and it keeps leaning the same way as it goes around the Sun. When our part of Earth tilts toward the Sun, sunlight shines more directly and the days are longer—that’s summer. When it tilts away, the sunlight is less direct and the days are shorter—that’s winter.
It’s not because Earth is much closer to the Sun in summer. And when it’s summer in the Northern Hemisphere, it’s winter in the Southern Hemisphere—like in Australia.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
