PLATE TECTONICS: Distribution of
volcanoes and mountain ranges
Page | 1
Content Standard: The relationship among the locations of volcanoes, earthquake
epicentres, and mountain ranges.
INTRODUCTION
At the end of this week, you are expected to attain the following objectives:
A. Describe the distribution of active volcanoes, earthquake epicentres and
mountain ranges of the world.
B. Compare the locations of earthquake epicentres, active volcanoes, and
mountain ranges of the world.
C. Relate the distribution of active volcanoes, earthquake epicentres and
mountain ranges to the Plate Tectonics Theory.

PRE-ASSESSMENT
A. Identification. Choose the word/s inside the box that fit/s the
description of the statements below. Use your answer sheet in answering.
Volcano Himalayas
1. It is an opening in the Earth's surface that can allow gasses, magma, and ash
to escape.
2. It is a concentration of heat in the mantle capable of creating magma.
3. These are pieces of the Earth’s surface that fit together just like a jigsaw puzzle.
4. A chain of volcanoes that develop parallel to a trench.
5. It is a series of mountain of hills ranged in a line connected by high ground.
B. True or False. On your answer sheet write the word TRUE if the statement
is correct and FALSE if the statement is not correct.

Last week, your lesson was about the distribution of
earthquake epicenters. You learned that earthquake
mostly occurs along plate boundaries. You also
REVIEW
learned that it is important to identify earthquake
prone areas so that precautionary measures can be
done and to ensure the safety of everyone.
Activity 1
Find Me!
OBJECTIVES
a. Identify the most active volcanoes in the Philippines and their locations.
b. Explain the advantages and disadvantages of having a volcano in one’s locality.
MATERIALS
Philippine Map
Paper, pen
PROCEDURE
Page | 4
The Philippines is one of the countries
situated in the circum - Pacific belt or the Pacific
“Ring of Fire”. This is the reason why our country is
a host of many geologic features like the presence of
volcanoes. There are about 24 active volcanoes in
our country and the most active are Mayon in
Albay, Taal in Batangas, Kanlaon in Negros Island,
Bulusan in Sorsogon.
On January 12, 2020 Taal erupted and that eruption has caused
severe damage to the agricultural and aquatic resources. About 3.06 billion
pesos was lost due to that natural event. Almost 50,000 families are
affected and the results were devastating.
The presence of volcanoes has both advantages and disadvantages.
That is why millions of people are still living in areas where volcanoes are
found. Some of the advantages are: volcanic materials ultimately break
down and weather to form some of the most fertile soil on Earth, another is
the internal heat associated with young volcanic systems has harnessed to
produce geothermal energy. Also, volcanoes produce spectacular scenery
like Taal and Mt. Mayon. This spectacular scenery attracts tourists and as
a result it gives livelihood to the locals. Volcanoes also produce precious
stones and some materials are now processed to produce beauty products.
On the other hand, volcanoes can be very dangerous. Violent
reactions could lead to tremendous hazards like suffocation, floods,
mudslide, power outages, drinking water contamination, and air travel
disruption among others. People should be vigilant enough especially
though who are living near a volcano.

Q5. What is the importance of volcanoes to humans?
Activity 2
Mark the Boundaries
OBJECTIVES
MATERIALS
Map of earthquake distribution
Map of active volcanoes of the world
1 piece plastic sheet with the traces of earthquake epicentres
1 piece plastic sheet used for book cover, same size as book pagE
Page | 7
PROCEDURE
1. Look at Figure 2-Map of active volcanoes. Observe the colored areas because it
represents the presence of volcanoes,
2. On the plastic sheet, sketch the approximate locations of several volcanoes
using a marking pen.
3. Place the earthquake plastic sheet over the volcano plastic sheet.

Activity 3
Top of the World
OBJECTIVES
PROCEDURES
2. Look at the colored areas and observe the distribution of mountain ranges.

3. Using the two plastic sheets (earthquake distribution and active volcanoes),
compare the locations of earthquake epicentres, active volcanoes, and
mountain ranges of the world.
QUESTIONS
Q1. How will you relate the distribution of mountain ranges with the
distribution of earthquake epicentres and volcanoes?
Q2. Where can we find earthquake epicentres, active volcanoes, and mountain
ranges of the world?
Q3. What theory governs the mechanisms of geologic activities which lead to
the formation of active volcanoes and mountain ranges?
Q4. What is Plate Tectonics Theory?
DISCUSSION
Mountain ranges are found in places where
volcanoes and earthquake epicentres are also located.
They are not randomly distributed and majority of them
are found in narrow zones, and along the edges of some
continents. The presence of volcanoes, earthquake
epicentres, and mountain ranges mark the boundaries
of tectonic plates.

I would like to extend my sincerest gratitude to my family
and friends for their encouragement and overwhelming
support from the start until the end.
This self -learning kit will help you explore and understand the
natural processes and events around us. It will enhance your
understanding about the occurrence of earthquakes, volcanoes,
and mountain ranges around the world.
