VOLCANO AND IT’S
PARTS
Volcano
Is a vent that directly
connects magma to
the surface of the
Earth.
8
It is also described as a
mountain or hill, typically
conical, having a crater or
vent through which lava,
rock fragments , hot
vapor, and gas are being
erupted from the Earth’s
crust

Crater
It is a funnel-shaped
depression of
the top of a volcano
formed as a result of
explosive eruption.
Caldera
It is a volcanic crater
that is formed when a
part of the wall of the
crater collapses
following an explosive
eruption.
Magma chamber
Is a large pool of liquid
rock beneath the
surface of the earth.
Magma chamber
Magma chamber
Magma
magma
Is extremely hot liquid
and semi-liquid rock
that comes from a large
underground pool of
molten rocks called the
magma chamber or the
magma reservoir.
Lava
Magma that has been
ejected out of a
volcano.
Secondary Vent
Are smaller outlets
through which magma
escapes.
Ash Cloud
Steeped-wall
depression at the
peak of the volcano
and the volcanic
vent.
What factors would cause a volcano to form?
3 predominate triggering factors:
18/05/2022
• The buoyancy of the magma
• The pressure from the gases in the
magma
• Injection of a new batch of magma
into already filled magma chamber
22
The movement of the
earth’s crust sometimes
causes a plate to slide
down the mantle. In the
mantle the plate is
gradually heated.
When the pressure becomes
high enough in the magma
chamber, magma forces its way
to the crust
What 3 ways are volcanoes formed?
• Divergent Boundaries (crust moves
apart, magma fills in)
• Convergent boundaries ( magma fills
when one plate goes beneath
another)
• Hot spots ( a large magma plume
rises from mantle)

25
DIVERGENT
BOUNDARIES
Volcanoes formed
when crust moves
apart and magma
Fills in
CONVERGENT
BOUNDARIES
Volcanoes formed
when one tectonic
plate moves under
another.
HOT SPOTS
Volcanoes formed
when a large magma
Plume rises from
mantle
Ex. Hawaii
What is the difference between a
volcano from a mountain?
FORMATION
Mountain is formed due to various geological
processes like movement and opposition of
tectonic plates but a
Volcano is formed around a vent that allows
magma to reach the surface of the earth.
29
1.What is the difference between magma and lava?
Do they have the same composition?
2. What is the importance of knowing the
parts of a Volcano?
It is important to know about volcanoes and it’s parts
because volcanoes spew hot, dangerous gases, ash, lava, and rock
that are powerfully destructive and it can kill hundreds and
thousands of lives.
31
Volcano
Why is Volcano important?
Volcanoes keep the Earth warm and wet, which are 2 critical elements for
sustaining life. Without volcano, most of the Earth’s water would still be
trapped in the crust and mantle.

the sentence below:

A volcano are formed in
what ways?

.
.
33
Arrange the statements about the formation of
volcanoes in their correct sequence. Write letter
A-E on ¼ sheet of paper.
1. In the mantle, the plate is gradually heated.
2. When the pressure becomes high enough in the
magma chamber, magma forces it’s way to the crust
and blows its top creating an opening.
3. The molten rocks (magma) collect in the magma
chamber.
4. The movement of the earth’s crust sometimes
causes plate to slide down the mantle.
5. This action releases steam that melts the rock on
the top of it.
Identify what is being described in each
statement below.
6. It is the opening at the peak of the volcano.
7. Molten rock expelled from a volcano during volcanic
eruption.
8. It is the rupture in the crust that allows hot lava to escape
from a magma chamber below the Earth’s surface.
9. It is consist of fragments of rocks, minerals, and volcanic
glass created during volcanic eruptions.
10. It is the Philippine National Institution dedicated to provide
information on the activities of volcanoes, earthquakes, and
tsunamis.
