What is the reason for the seasons?
What is the angle Earth is tilted on its
axis?
How is the Earth tilted during summer and
winter?
How is the Earth tilted during spring and
fall?
What angle is the Earth tilted for no
seasonal change?
Why do shadows appear longer in the
winter?
Seasons
1.
The Earth has seasons
because it is tilted on its
axis.

2. The Earth’s tilt is 23.5 degrees


3. The hemisphere that is tilted
toward the sun has summer.
The hemisphere that is tilted away
from the sun has winter

4. Spring and Fall occur when the
Earth is neither tilted toward or away
from the sun

5. The Earth would need to be a a 0
degree angle for the Earth to have no
seasons

6. Shadows appear longer because
sunlight reaches the Earth at different
angles
