The document explains the concept of seasons, the Earth's rotation and revolution, and describes how the tilt of the Earth affects temperature and day length in different hemispheres. It details significant solstices and equinoxes marking the start of summer, winter, spring, and autumn. Additionally, it highlights the experiences of various regions, notably how countries in the Northern and Southern Hemispheres are affected by solar rays throughout the year.

1. Seasons and the
position of the
sun in the sky

2. a. Define seasons;
b. explain
axis, revolution, rotation; and
c. describe the tilt of the earth to
the length of day time

6. PHILIPPINES SEASON

10. Rotation
it refers to an object’s spinning motion about its own axis.
It takes 24 hours or one day for the earth to completely
rotate around on its axis.

12. Revolution
It refers to the movement of a planet around the sun.
1 revolution = 365 days or one year for the earth to move
around the sun.

14. SEATWORK:
Directions: Look at each picture, explain what is in the picture
and write which season it represent.

16. Hemisphere receives
more solar rays
experience warmer
temperature.
The hemisphere that
receives lesser solar
rays will experience
cooler temperature.

18. • The first day of summer is marked
by the summer solstice which
occurred during June 21 and June
22.
• And the first day of winter is
marked by the winter solstice
which occurred during December
21 or 22.

19. April to august different countries located north of
the equator will received direct rays and experience
summer.

20. Southern hemisphere during the month of
June receives lesser direct rays from the sun. It
experiences a shorter period of day time and a
longer period of night time.

21. The longer daytime will cause the surface of
the earth to heat up for a longer period. The
shorter period of nights will cause a lesser
time of the earth’s surface to cool down.

22. • Countries in north hemisphere-
this area experience the time
of cold, countries located in the
temperate zone will experience
winter.
• And countries located in the
tropical region, such as the
Philippines will experience the
cold season

23. • In the month of December it
is the south pole that tilted
toward the sun, it is the
southern hemisphere that
receives more directories
from the sun.

26. • The first day of spring is marked by the
vernal equinox which happens on march 21
or 22. It is spring in the north and autumn
in the south.
• The first day of autumn season is marked
by the autumnal equinox which happens on
September 21 or 22. It is autumn in the
north and spring in the south.
