What is How long does it take Earth to rotate once on its axis?
300
The Earth's tilt causes this. The different angles of sunlight mean that the seasons are always opposite in northern and southern hemisphere.
What is Why do the Northern and southern Hemispheres have opposite seasonal experiences?
300
Because Earth is tilted on its axis, different parts of the planet receive different amounts of sunlight throughout the year
What is What causes the cycle of the seasons?
300
The moon rotates on its axis once every 28 or 29 days.
What is Why does the moon's appearance change in predictable ways over time?

What is orbit?
500
Earth's rotation makes the sun, stars and planets look like they are moving. Really, it's Earth that's moving.
What is How does Earth's rotation affect the way we view the planets, the sun, and the stars around us?
500
The earth revolves around the sun throughout the year, that portion of the night sky we see, and therefore individual constellations, is constantly changing.
What is Why are different constellations visible at different seasons of the year?
500
Because Earth is tilted on its axis, different parts of the planet receive different amounts of
sunlight throughout the year.
