THE SEASONS
Although the distance between the Earth and the sun varies on an annual cycle, this change is too small to cause seasons. Our seasons are caused by the 23½° tilt of Earth’s axis. This tilt causes the sun’s path through the sky to change throughout the year. Summer starts when the noon sun is the highest in the sky, and when the sun is in the sky for the greatest length of time. In the Northern Hemisphere, the longest day, and the day when the noon sun is the highest in the sky, occurs about
June 21. That’s when our sunlight is the most direct. But, south of the equator, this is also when the sun is lowest in the sky and when the days are the shortest. Therefore, the seasons are six months out of phase north and south of the equator. The second diagram is an oblique view of Earth’s orbit around the sun.

2. Why doesn’t the changing
distance between the Earth and the sun affect the seasons?
3. What actually causes seasons?
4. When it is summer in the Bay Area, in Argentina and South Africa it is
Of course, in our observations from Earth, we note the changing path of the sun through the sky, rather than the movement of our planet in its orbit.
5. According to this diagram, how high is the noon
sun in the Bay Area on June 21?
6. How high on December 21?
7. What is the annual range? (the change in altitude) (= 2x 23½)
