Good morning class!
Good morning Ma’am.
Please remain standing for our opening
prayer.
*students will start to pray
their daily prayer*
Class before you seat kindly fix your chair
and pick up all those pieces of trashes.
Are there any absents for today’s session?
A. Preliminary
Activities
Before we start our lesson, I have here some
friendly rules for you to follow during our
class session. Always be:
None, Ma’am.
 Always be kind
 Cooperate in the
class
 Treat others with
respect
 Instill discipline
 Volunteer to
participate
 Encourage to
recite
Let us have first a quick recap about what
was learned last meeting. I have here words
that are disarranged. I will call some
volunteers or those who wants to recite and
come in front to arrange these words to
come up with the correct statements.
Direction: Arrange the disarranged
words to form a sentence or statement.
Each statement should be arranged
within 30 seconds.

volcanoes. These include dissolved
gases in magma and lava or gases
emanating from lava, gases trapped in
vesicles in volcanic rocks, and even
emitted by groundwater heated by
volcanic eruptions.
Volcanoes release gases when they erupt,
and through openings called fumaroles.
They can also release gas into soil and
groundwater.

As shown in the picture, the main component
of volcanic gas emissions is water vapor,
carbon dioxide, sulfur dioxide, and hydrogen
sulfide.
What is again a lava, class? Any idea about
it?
Lava
is
a
molten
rock(magma)
that
is
ejected out from the
interior of the earth. The
ease with which lava
flows and the structures it
forms depends on how
much silica and gas the
lava contains.
A lava flow is a moving outpouring of lava
created during a non-explosive effusive
eruption.
The following are the lava flow materials and
pyroclastic materials that are ejected from
the opening of volcanoes. Here are the
following lists of various volcanic material
with their definitions.
Please read what is a lava flow materials?

We move with the other materials that are
ejected from the explosion. These are the
pyroclastic materials. These pyroclastic

ejection from a volcanic vent.

volcano into the atmosphere.
The following pictures are some of the
lava and pyrocrastic flows.
Please study these pictures and take note
of the different styles of these materials.
As we can see, there are also types of
rocks in the pictures presented.
How

do
volcanic
eruptions affect our society?
Any idea about this, class?
A volcanic eruption is often associated
with both positive and negative effects.
Our planet, the Earth is active,
geologically speaking and as such, it
undergoes a process of constant renewal
by way of volcanic eruptions. Volcanoes
erupt when magma reaches the surface
due to high pressure and starts to pool in
a magma chamber.
Apart from enhancing soil fertility, the
resultant eruption also helps to bring
out various precious minerals buried
deep in the earth such as Diamond,
Opal, Garnets, emeralds and much
more.
Volcanoes can provide you with a
ready source of power since the same
can be tapped by geothermal power
stations and help to power up the
various cities located close by.
A good example of the eruption is the
Pinatubo Volcano which created a
spectacular view resulting in an income
generation of the community that attracts
lots of tourists.
Figure 3. Pinatubo Crater Lake

The lava that blasted
from the eruption makes
the soil fertile, but this
can be done after years
of eruption.
All volcanic eruptions result in
widespread damage to the point that
whole cities are destroyed along with
the entire local infrastructure. This can
impact the local population on several
levels, and it can take a while before
the city can be reconstructed. It can
cause loss of lives and properties.
Even though a volcanic eruption leads
to increased fertility in the soil, the
process takes time. Meanwhile, the fall
out on the local environment is
immediate with ash, toxic gases all of
which impact the local flora and fauna.
CLASSIFY ME!
To check your comprehension to our lesson.
I want you to answer this one individually in a
¼ sheet of paper.
Classify the effects of volcanic eruption if it is
positive or negative effects. Write positive if
the statement says positive effect, and write
negative if it is otherwise.
