Using models or
illustrations, explains how
movements along faults
generate earthquakes
(S8ES-IIa-14)
LESSON OBJECTIVES:
1. explain what a fault
is and how it is formed.
2. make a model of the
formation of fault; and
3.show tips about
precautionary measures
when you are living in
areas near faults by
giving an example
through a role playing.

Activity Objectives:
After performing this
activity, you will be able
to:
1. Describe the
appearance of fault; and
2. Explain how a fault
forms

SHORT ACTIVITY

a. As you move the sheets, what is
formed in the sand?
b. What happened to the lines?
GUIDE
QUESTIONS:

14. As you performed the activity what
happen when you move the sheets?
What is formed in the sand?

15. WHO CAN DESCRIBE THE APPEARANCE OF THE
FAULT?
-A fault is a fracture or zone of fractures between two
blocks of rock. Faults allow the blocks to move relative to
each other. This movement may occur rapidly, in the form
of an earthquake. The fault surface can be horizontal or
vertical or some arbitrary angle in between.

16. EXPLAIN HOW A FAULT IS FORMED
A fault is formed in the Earth's crust as a brittle response to stress.
-The movement of the tectonic plates provides the stress, and rocks at the surface
break in response to this.
The sense of stress determines the
type of fault that forms, and we usually
categorize that sense of stress in three
different ways:
1.Compression (reverse fault)
2.Tensional stress (normal fault)
3.Shear (strike-slip-fault)

earthquakes; and
2. Explain why not all movements
along faults produce earthquakes.

EXPLAIN
(Developing mastery leads to
Formative Assessment)
What is a Fault?
It may be defined as a
fracture surface in rock
across which there is
relative motion parallel to
the surface between the
adjacent blocks of the
rock.

26. HOW DO FAULTS
PRODUCE
EARTHQUAKES?
Energy from inside the earth make the
ground move. There is no movement right
away because of the Friction. Friction held
the rocks together. Once the friction is
overcome, the ground will move and
earthquake will occur.

Evertime a FAULT
slips or moves, the
EARTH QUAKE.
EARTHQUAKE
-The shaking or trembling
caused by the sudden release
of energy.
-it occur when rocks along
fault suddenly move.

27. KNOWING THE FAULT

29. FOCUS

is the place where the
first break happens,
where the fault starts to
slip, where the first
movement takes place. It
is the starting point of
the earthquake.
