Let’s Mark the
Boundaries
Activity 2

Objectives:
1. Describe the distribution of active
volcanoes, earthquake epicenters, and
major mountain ranges (S10ES-Ia-j-36.1)
2.Determine the scientific basis in
dividing the lithospheric plates

Q1. How are earthquakes
distributed on the map?
Answer:
The world’s earthquakes
are not randomly distributed
over the Earth’s Surface.

Q2. Where are they
located?
Answer:
Some are located near the
edges of the continents, some are in
the mid-continents, while others
are in oceans.

Q3. Where are places
with no earthquakes?
Answer: The places where there are no
earthquakes are large part of the Pacific
Ocean, Northernmost Asia, majority of
Europe, Eastern part of North and South
America and Western Africa.

Q4. Why do you think it is
important for us to identify
area which are prone to
earthquakes?
Answer: It is important to identify areas
which are prone to earthquakes so that
necessary precautions could be done if
ever you are living in one of those places.

Q5. How are volcanoes
distributed?
Answer:
Volcanoes are not
randomly distributed. Majority of
them are found along the edges
of some continents.

Q6.Where are they
located?
Answer:
Majority of them are found along
the edges of some continents,
particularly in the western coast of North
and South America and Southeast Asia.

Q7. Based on the map,
state a country that is
unlikely to experience a
volcanic eruption?
Answer:
Countries that are located in
Europe, Eastern part of North and South
America, etc.

Q8. Compare the location of
majority of earthquake
epicenters with the location of
volcanoes around the world?
Answer:
Earthquake epicenters and
volcanoes are both situated at the

Q9. How will you relate the
distribution of mountain ranges
with the distribution of
earthquake epicenters and
volcanoes?
Answer:
Mountain ranges are found in
places where volcanoes and earthquake
epicenters are located.

Q10. What do you think
is the basis of scientists
in dividing the Earth’s
lithosphere into several
plates?

Answer: Geologic activities
such as seismicity (occurrence
of earthquake), volcanism and
mountain formation are the
basis of scientists in dividing the
Earth’s lithosphere.

Key Concepts:
Plates are large pieces of
the upper few hundred
kilometers of Earth that move
as it floats above the mantle.

Key Concepts:
The plates are in constant
motion. As they interact along their
boundary, important geological
processes/event take place such as the
formation of mountains and
volcanoes and occurrence of
earthquake.
