Q & A
What are the five health tips mentioned by Teacher Melvin for maintaining back, neck, and eyes while watching screens?
-The five health tips are: 1) Sit properly with your back touching the chair backrest. 2) Change your position regularly if watching for long periods. 3) Keep dim lighting on in the room instead of no or strong lighting to prevent eye damage. 4) Use commercial breaks to change positions, walk around, and do gentle stretches. 5) Avoid watching TV in bed to prevent neck and back ache.
What is the significance of plate tectonics in understanding the earth's surface features and movements?
-Plate tectonics is significant because it explains the features and movements of the earth's surface, both in the present and the past, based on the distribution of active volcanoes, earthquake epicenters, and mountain ranges.
What is the challenge presented in the script and what are the required materials for it?
-The challenge is a 'Mystery Word' game where participants must guess words based on hints. The required materials are a pen, paper, and the ability to write down the correct word within five seconds for each level of the game.
How many gold coins are needed to fuel the canister to 100% in the game, and what is the reward for each correct answer?
-Five gold coins are needed to fuel the canister to 100%. For every correct answer in the game, one gold coin is awarded.
What is the epicenter of an earthquake and why is it important in understanding plate tectonics?
-The epicenter is the part of the earth's surface directly above the focus of an earthquake. It is important in understanding plate tectonics as it indicates the location of seismic activity, which is often associated with the movement of tectonic plates.
What is a seismograph and how does it relate to the study of earthquakes?
-A seismograph is an apparatus used to measure and record vibrations within the earth and off the ground. It is crucial in the study of earthquakes as it helps in detecting and measuring the intensity of seismic events.
What is the lithosphere and how does it differ from the asthenosphere?
-The lithosphere is a 100-kilometer thick layer of solid rock including the crust. The asthenosphere is the upper mantle beneath the lithosphere, which is also solid but softer due to high pressure and high temperatures, and can be compared to the consistency of butter.
What are the seven large tectonic plates mentioned in the script?
-The seven large tectonic plates are the African, Antarctic, Eurasian, North American, South American, Indian-Australian, and the Pacific plates.
Why is the Philippines considered a part of the 'Ring of Fire' and what does this imply?
-The Philippines is considered part of the 'Ring of Fire' because it is situated in a region where plate tectonics are very evident, characterized by frequent earthquakes and volcanic eruptions. This implies that the country is prone to geophysical hazards.
What is the significance of the 're-circle the ring' activity in understanding the distribution of active volcanoes and plate movements?
-The 're-circle the ring' activity helps in visualizing the distribution of active volcanoes and plate movements around the Pacific region, illustrating the relationship between these geological features and the tectonic plate boundaries.
What is the purpose of the pop quiz at the end of the script and how does it engage the audience?
-The pop quiz serves to test and reinforce the audience's understanding of the concepts discussed in the script. It engages the audience by challenging them to recall information quickly and rewarding correct answers with a 'gold coin' metaphor.

canister to one hundred percent
that's great how many words have you
correctly remembered
i'm happy to know that you can still
recall important scientific terms
which you learned in your previous
science explorations
let's explore more
[Music]
did you know that the ground we stand on
is always
moving wonder warriors let's zoom in
below the cross on which we live is the
earth's mantle
the 100 kilometer thick layer of solid
rock including the crust
is called the lithosphere the upper
mantle that lies beneath the lithosphere
is called the asthenosphere the
asthenosphere is also solid
but the rock here is softer due to high
pressure and high temperatures
in some ways the consistency of the
asthenosphere can be compared to that of
a butter
even though it is solid it can be
pressed and molded
differences in temperatures between the
inner and outer parts of the
asthenosphere
allow convection to occur convection
in the asthenosphere forms the
foundation of plate tectonics
according to the plate tectonics theory
the entire lithosphere of the earth is
broken into numerous segments
called plates
and now please refer to your
self-learning module
take a look at this figure
[Music]
what does the figure show the figure
shows
the moving plates of the earth can you
see the arrows
what does the arrow imply the arrows
show the direction of the plate movement
and other lines are default lines
now let's zoom out a little
the earth has small and large plates
there are seven
relatively large plates and several
smaller ones including the philippine
plate
can you recall the seven large baits
these include african antarctic
duration north american
south american india australian
and the pacific place
spectacular i'm happy to know that you
can still recall the seven large plates
whether large or small these plates
relate to natural phenomenon or geologic
activities
such as earthquakes volcanisms
and mountain formations to better
understand this let us perform
this activity for this one
you may refer again to yourself learning
module
i'm going to share three maps which you
need to observe carefully
[Music]
draw your attention to this map
what does the map show this map
shows the earthquake distribution around
the world
the dark areas of the map are the
earthquake epicenters take note
of the areas where they are closely
situated
based on the map how are earthquakes
distributed
the world's earthquakes are not randomly
distributed over the earth's surface
they tend to be concentrated in narrow
zones
and where are they situated
some are located near the edges of the
continents
some are in the mid-continents while
others are in the ocean
now let's have the second map
what does the map show this map shows
the earth's major volcanoes
take note that the dark dots are the
active volcanoes
and how are volcanoes distributed
volcanoes too are not
randomly distributed majority of them
are found
along edges of some continents and where
are they situated
majority are found along the edges of
some continents
particularly in the western coast of
north and south america
east and southeast asia and finally
take a look at the third map
what does this map show our third map
shows the distribution of the earth's
mountain ranges
take note that the coarse and darker
areas in the map
are the mountain ranges of the world the
himalayas are the great mountain system
of asia
this include the highest mountains in
the world
with more than 110 peaks rising to
elevations of 24
000 feet or more above the sea level
one of those is the mount everest
the world's highest with an elevation of
29 035 feet
the cordillera central more commonly
known as the cordelieras
is a gigantic array of mountains
dominating the whole western half of
northern luzon
it is the largest of all the mountain
ranges in the philippines
constituting around a sixth of the
entire land area of the zone
from north to south the entire
cordillera central spans
320 kilometers long and encompasses all
the provinces of the cordillera
administrative region
another notable mountain range is the
sierra madre
also known as the backbone of luzon did
you know that shera madre is the longest
mountain range in the philippines
it covers the northeast coast of luzon
island
serving as natural shield against
typhoons coming from the pacific ocean
the range also comprises numerous
watersheds
that serves the adjacent agricultural
lands in central luzon
and kageyang valley how's the learning
exploration so far
wonder warriors always remember to take
note of the important details in a piece
of paper
by taking notes you can easily remember
what you learned in the activity
got it way to go wonder warriors
you observed in the activity that
earthquake epicenters
volcanoes and mountain ranges are close
to each other
if not situated in the same locations
have you ever wondered
how this could be possible let's
zoom in remember that plates are in
constant motion
as they interrupt along their margins
important geologic processes
take place such as the formation of
major mountain ranges
active volcanoes and earthquake
epicenters
it means to say that where there are
earthquakes crust
can either meet or move apart and form
mountains and volcanoes
plate movements may result in
earthquakes and earthquakes may happen
any time either on land or underwater
earthquakes on land can be caused either
by tectonic plate movement
or volcanic eruptions earthquakes under
the sea can cause a tsunami
according to experts it is estimated
that there are 500 000 detectable
earthquakes in the world each year
one hundred thousand of those can be
felt and one hundred of them can cause
damage
our country the philippines is situated
in a place where plate tectonics are
very evident
the ring of fire it is a long chain of
volcanoes and other
tectonically active structures that
surround the pacific ocean
the ring of fire is one of the most
geologically active areas on earth
and a site for frequent earthquakes and
powerful volcanic eruptions
did you know that the ring of fire is
also called as the circum-pacific belt
and about 90 percent of the world's
earthquakes occur there
to better understand this let us perform
an enrichment activity
let's call this activity as the
re-circle the ring
for this activity you will need the
following materials
a separate piece of paper
a pencil and your self
learning module to start
take a look at this figure
[Music]
what do you see it shows the active
volcanoes
represented as triangles all over the
pacific region
let's label this figure as one
and compare this to another figure and
label it as two
you will realize that the active
volcanoes shown in the figure 1
are also situated in the areas of the
plate movement
as shown in figure 2. can you spot it
using the map in figure 1 which volcano
is familiar to you and why
you probably say mount pinatubo an
active volcano located on the island of
luzon in the philippines
at the intersection of the borders of
the provinces of zambales
and pampanga did you know that on june
15
1991 mount pinatubo volcano exploded
which was the second largest volcanic
eruption in the 20th century
[Music]
other notable volcanoes include the
mount
fuji in japan which is an active volcano
it stands at 3776 meters
and the mount st helens in washington
which is known as the world's famous
natural laboratory for the study of the
earth's
processes and also nature's response to
catastrophe
why this area is called the pacific ring
of fire
that's because active volcanoes faults
and earthquake epicenters almost
surround the pacific region
so there you have just learned about the
plate tectonics
based on the distribution of active
volcanoes
earthquake epicenters and mountain
ranges on our planet
wonder warriors let us see if we have
grasped the essence of today's
exploration
let's have a five item pop quiz kindly
prepare
your paper and pen for this pop quiz i
will read the question
and choices once you are only given
five seconds to write the letter of the
correct answer for each question
you will be given one gold coin for
every correct answer
