5. What are Seismic Waves?

6. Seismic waves are waves of
energy that travel through Earth's
layers.

8. Seismic Waves

9. What causes the production of
Seismic Waves?

10. Seismic waves are caused by

11. During an earthquake, where do
the seismic waves originate?

12. During an earthquake…
Seismic waves radiate from the focus of an
earthquake

13. what is the role of seismic waves
in the study of the internal
structure of Earth?

14. Inner Core
Outer Core
Mantle

19. 1. Describe the process of typhoon
formation
2. Find out why Philippines is
prone to typhoon.
3. Determine the reason behind the
formation of LPA.

20. Have you experienced a typhoon
before?

21. According to PAGASA, the
Philippines is visited by an average
of 20 typhoons every year.

22. Why is the Philippine archipelago
prone to typhoons?

23. Geographical location of Philippines

24. Philippines is within the typhoon belt in
the Pacific

27. Warm Ocean is one of the
prerequisite conditions for typhoon
formation

30. Activity #1

31. Instruction
▪ Refer to Science Activity Sheet #4 page 2.
▪ Try to analyze each illustration in column
A and the random processes in column B
▪ Then, match each illustration with the
correct description of the process.

32. Typhoon Formation

33. Notes to remember..
• For every illustration with correct description of
process, you will get 2 points.

34. Notes to remember..
• Soft copy of the activity will be uploaded on
the group chat for those who don’t have
science activity sheet at home.
• Submit your answer sheets (softcopy or
photo of it) on my gmail account:
johnpauldejuan25@gmail.com or personal
submission by your parent in school.

35. ACTIVITY PROPER

36. Warm and moist air
moves up and away
from the surface.
Typhoon Formation

37. The upward motion of the
air creates Low Pressure
Area (LPA) near the
surface.
Typhoon Formation

38. Typhoon Formation
HPA HPA
Air from surrounding
areas with higher air
pressure moves toward the
low-pressure area.

39. Typhoon Formation
The new air becomes warm
and moist and rises, too. As
the warmed, moist air rises
and cools off, the water in the
air forms the clouds.

40. Typhoon Formation
The whole system of clouds
and wind movements
depend on ocean’s heat and
water evaporating from the
surface.

42. Why do typhoons mostly form in
oceans near equator?

43. Sea Surface Temperature

44. What type of heat transfer is
responsible for the high rate of
evaporation in oceans near equator?

45. Solar
Radiation

46. What causes the upward motion of
the warm air?

47. Lower Density

48. What is Low Pressure Area?

50. Low Pressure Area

51. Have you watched a weather
forecast?

52. What happens to typhoon when it
makes a landfall?

53. Activity #2

54. Instruction
• Refer to your Science Activity Sheet #4 – page 3-4
• Study the given illustrations and find out the effect
of landmasses and bodies of water to typhoon.
• After analyzing the illustrations, complete the table
(page 4) to show the correct behavior of typhoon as
it moves

55. Soft copy of exam will be sent
on your personal emails

56. Do some advance reading about tracking
typhoons.
