The document discusses geologic processes and hazards, focusing on natural events such as earthquakes, volcanic eruptions, and their associated dangers like tsunamis and landslides. It outlines learning objectives for students, including identifying geologic events and understanding their impacts on people and the environment. Additionally, it includes activity suggestions for students to engage with the material and to consider the importance of preparedness in response to such hazards.

2. Short video clips

3. Processed Questions
• What do you see from the video?
• What do you think are these phenomena
natural or man-made?

4. Learning Objectives:
During or after the discussion the students will
be able to:
1. identify the two major geologic events;
2. explain the hazards may cause by these
geologic events;
3. make a slogan on the effect of geologic
hazards to the people and the environment; and

PROCESSES AND
HAZARDS

6. Geology
• is the study of the Earth and its history.
It involves studying the materials that
make up the earth, the features and
structures found on Earth, as well as the
processes that act upon them.

7. How do geological processes occur?
• Geological processes are naturally occurring
events that directly or indirectly impact the
geology of the Earth.
• plate tectonics, weathering, earthquakes,
volcanic eruptions, mountain formation,
deposition, erosion, droughts, flooding, and
landslides.

8. How about Geologic Hazards?
• A geologic hazard is an extreme natural
event in the crust of the earth that poses
a threat to life and property, for
example, earthquakes, volcanic
eruptions, tsunamis (tidal waves) and
landslides.

10. Activity #1. ARRANGE ME
Direction: I will be showing series of
pictures for you to identify. Each
picture is rumbled letters for you to
rearrange correctly forming into a
word. (2pts each)

15. How do geological processes occur?
• Geological
processes are
naturally
occurring events
that directly or
indirectly impact
the geology of
the Earth.

16. How about geologic hazards?
• A geologic hazard is an
extreme natural event
in the crust of the
earth that poses a
threat to life and
property, for example,
earthquakes, volcanic
eruptions, tsunamis
(tidal waves) and
landslides.

GEOLOGIC HAZARDS

19. Earthquake

20. Earthquake
• is one of the most violent natural phenomena.
• According to the number of victims and
destructive force, it exceeds all other natural
disasters.
• Earthquakes also happen under the ocean and
can cause tsunamis.
• Earthquakes and volcanic eruption can trigger
landslides

21. • Philippine earthquakes -noticeably strong
such as magnitude 6.9 in October 2019
which hit southern Philippines.
• Another one was 6.1 magnitude that
struck the Island of Luzon in April of
2019.
• Recently, multiple earthquakes were felt
when Taal Volcano erupted early in
2020.

22. Have you experienced an earthquake?
What did you feel?
How about the earthquake we have
experienced 7 years ago, here in our city?

24. Listed below are the hazards caused by an
earthquake:
Ground shaking
• is one of the hazards
resulting from
earthquake, volcanic
eruption, and
landslides.
• Ground shaking
describes the vibration
of the ground during
an earthquake.

25. Listed below are the hazards caused by an
earthquake:
• is displacement that
reaches the earth's
surface during slip along a
fault.
• It commonly occurs with
shallow earthquakes;
• Surface faulting also may
accompany aseismic creep
or natural or man-induced
subsidence.
Surface faulting

26. Listed below are the hazards caused by an
earthquake:
• the movement of a mass
of rock, debris, or earth
down a slope.
• Landslides are a type of
"mass wasting,“
• The term "landslide"
encompasses five modes
of slope movement: falls,
topples, slides, spreads,
and flows
Landslide

27. Listed below are the hazards caused by an
earthquake:
• describes the way in
which soil liquefies
during ground shaking.
• Liquefaction can
undermine the
foundations and supports
of buildings, bridges,
pipelines, and roads,
causing them to sink into
the ground, collapse, or
dissolve.
Liquefaction

28. Listed below are the hazards caused by an
earthquake:
Tsunamis
• These are giant waves
caused by earthquakes
or volcanic eruptions
under the sea.
• It can injure or kill many
people and cause
significant damage to
buildings and other
structures.

29. Listed below are the hazards caused by an
earthquake:
Tsunamis • The speed of tsunami
waves depends on
ocean depth rather than
the distance from the
source of the wave.
• Tsunami waves may
travel as fast as jet
planes over deep waters,
only slowing down when
reaching shallow waters.

30. What are volcanoes?

31. Volcanoes
• A volcano on Earth is
a vent or fissure in the
planet's crust through
which lava, ash, rock
and gases erupt.
• Volcanoes are natural
systems and always
have some element of
unpredictability.

32. What about volcanic eruption?
• A volcanic eruption occurs when magma is
released from a volcano.
• Volcanic eruptions are major natural hazards
on Earth.
• Volcanic eruptions can have a devastating
effect on people and the environment.

33. These are the hazards caused by volcanic
eruption:
Tephra pyroclastic flow

34. These are the hazards caused by volcanic
eruption:
Lahar Flood

35. These are the hazards caused by volcanic
eruption:
Lava domes Poisonous Gases

36. Activity #2
Direction: Each group will be given a Manila
Paper, containing metacards where you are
going to write your answers in every question
that I am going to throw. Paste your metacards
with your answer in the manila paper. Once
done, post your Manila papers in the Board.
No changing of answers this time, for we will
check it by then.

37. Guide Questions:
1. What are the two Major geologic events?
2. How many hazards may cause by
Earthquake? How about Volcanic Eruption?
3. What are the possible hazards caused by
Earthquake? Explain each.
4. What are the possible hazards caused by
Volcanic Eruption? Explain each.

38. Activity # 3. “My Geologic Hazards Experience”
• Cite at least four (4) hazards you have
experienced in your locality. Then make
a slogan on how these hazards affect
the people as well as the environment.
