What is the difference between rotation and revolution?
Rotation is a single sphere spinning on an axis and revolution is when a sphere revolves around another sphere.
What occurs during a solar eclipse?
The moon blocks out the suns rays from reaching the Earth.
Would we still have seasons if there was no tilt of the Earth's axis?
No. If there was no tilt, the amount of sunlight hitting the world would be consistent in all areas, just making one season.
If May, June, and July are the summer months in the Northern Hemisphere, which place would be warmer in the month of July? Southern Africa or the United States?
United States! Remember, Northern and Southern hemispheres have opposite seasons, so when it is summer here, its winter over there!
Every Planet in our solar system has the same seasons as we have. True or False
False
What latitude do you live at?
20-30 degrees South
How is the Moon different from the Earth?
The moon has less gravity and is 1/5 the size of Earth.
In winter, do we receive more direct sunlight or less direct sunlight?
Less direct sunlight = cold weather

If there was another planet in a different solar system with the same environment and distance away from the sun but it didn't have a tilt in its axis, would it still have four seasons?
No. The earth's tilt is mandatory in order for us to have four seasons. It makes sure that we're exposed to different amounts of direct sunlight in a year.
