The elliptical path that Earth takes as it revolves around the sun

At what time of day will your shadow be the shortest? At what TWO times of day will your shadow be the longest?
midday= short
sunrise and sunset= long
The four cardinal directions are...

If you looked at your shadow at the same time of day in winter and in summer, your shadow would be _________ in summer than it is in winter. Why?
shorter, because the sun is lower in the sky in winter, even at midday, and so the shadows would be longer than in summer.
Explain the difference between rotation and revolution
Rotation the Earth does not change position, but spins on it's axis. Revolution is the Earth moving (changing position), as it orbits around the sun.
You are walking in the park. Your shadow is long and in the East. What time of day is it? How do you know?
If your shadow is long and in the East, then the sun must be low in the West, so it is late afternoon
Imagine the Earth rotates north to south (instead of east-west). a) How would night and day be the same as they are currently? b) How would night and day be different than they are currently?
a) similar hours of day and night b) the sun would rise and set in the north and south
