3. What is the meaning of season
Seasons are created by two very
important events – the rotation of
the Earth that gives us day and
night, and the rotation of the Earth
around the sun that gives us our
year. Because the sun never
changes, only the movement of the
Earth creates changes in light and
darkness, and in temperature.

4. How does winter and summer season happen
• The Earth takes 365.24 days to
orbit the sun. As we move
around the Sun during the year,
the amount of light each area of
the planet receives varies in
length.
• When the Earth's axis points
towards the Sun, it is summer
for that hemisphere. When the

5. winter
•The coldest season of the year,
in the northern hemisphere
from December to February
and in the southern hemisphere
from June to August.

6. spring
•On the spring, day and night are each
approximately 12 hours long (with the
actual time of equal day and night, in the
Northern Hemisphere, occurring a few
days before the vernal equinox). The Sun
crosses the celestial equator going
northward; it rises exactly due east and
sets exactly due west.

7. Summer
•On the summer , we
enjoy the most daylight of the
calendar year. The Sun reaches
its most northern point in the sky
at local noon. After this date, the
days start getting "shorter," i.e.,
the length of daylight starts to
decrease

8. Autumn
On the autumn, day and night are each about 12 hours long
(with the actual time of equal day and night, in the Northern
Hemisphere, occurring a few days after the autumnal
equinox). The Sun crosses the celestial equator going
southward; it rises exactly due east and sets exactly due
west.
