Seasons on Different Hemispheres
Earth's Movement
100
How many degrees is Earth tilted?
23.5 degrees
100
Why are there different Seasons in the northern and southern hemispheres?
Because of Earth's tilt. The northern and southern hemispheres are closer to the sun at different times, thus they have different seasons at different times.
100
The spinning of earth around its _____________ is known as rotation.
axis
200
True or false: Earth's axis points toward different directions throughout the year.
False! Earth's axis is always pointing toward the same direction.
200
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!
200
What is the movement of Earth around the sun called?
Revolution
300
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 causes the four seasons. The axial tilt causes Earth to be exposed to different amounts of direct sunlight throughout the year.

If it was winter here in Virginia, and you wanted to go someplace warm, which vacation spot would be your best bet? *Remember! Northern and Southern hemispheres have opposite seasons.* a) Russia b) Japan c) Australia

365 days
400
When we have our winter, do we receive more direct sunlight or less direct sunlight?
Less direct sunlight = cold weather

Earth is moving over 60,000 miles an hour through space. If we are moving so fast, why don't we all fly off?
Gravity forces us down and stops us from flying off of Earth's surface.
500
Venus and Jupiter have very slight axial tilts. Do they have seasons?
No! A significant axial tilt is required for seasons to occur.
500
If it was summer in Maryland, with very warm temperatures what would the temperatures be like in Ecuador, which is found along the Equator?
Very warm. Areas along the Equator always receive direct sunlight and are very warm.
500
True or false: Earth's elliptical orbit contributes to its seasons. Explanation required!
