INTERMEDIATE
A.Using the map of the tectonic plates, identify the at
least 5 major and 5 minor tectonic plates. Use theRED
PUSH PIN icon to mark the MAJORtectonic
plates and the GREEN PUSH PIN icon to mark the
MINOR tectonic plates in unlabeled the map. Write the
names of your identified plates on the table on the next
slide. (10 points)

11. Questions
Q1. What can you say about the distribution of earthquake
epicenters in the map?
11
<answer>
Q2. Why is it important for us to identify the places which
are prone to earthquakes?
<answer>
around the Pacific Ocean in a region called the “Ring of Fire.” These areas are highly
active in terms of seismic movements.
Most earthquake epicenters are located along the edges of tectonic plates, especially
safer structures, and reduce the risk of injuries and damage during
It is important to identify earthquake-prone areas so people can prepare, build
earthquakes.

C. Map of mountain ranges and belts

14. Questions
Q3. Compare the location of majority of earthquake epicenters withthe location of
active volcanoes around the world. What can you infer regarding the comparison?

Q4. Compare the location of majority of earthquake epicenters withthe location of
active volcanoes and major mountain belts around the world. What are the things
that you discovered?

earthquakes and active volcanoes, indicating that both are primarily driven by tectonic activity.
and the boundaries around the Indian Ocean. This suggests a strong correlation between the locations of
the distribution of active volcanoes. These areas include the Pacific Ring of Fire, the Mid-Atlantic Ridge,
The majority of earthquake epicenters are located along tectonic plate boundaries, which closely match

boundaries. For example, the Himalayas, the Andes, and the Alps coincide with zones of frequent seismic
activity and volcanic presence. This reveals that tectonic plate interactions not only cause earthquakes
and volcanic activity but also contribute to the formation of mountain ranges. Hence, these geological
Most earthquake epicenters, active volcanoes, and major mountain belts are found along tectonic plate

15. Task
On the map below, trace the areas with high seismic activities (A)
with blue , areas with active volcanoes (B)red, and areas with major
mountain belts (C)green. Use the ppt drawing tool (or other tools of
your choice, make sure to fulfil the task objective)

Q5. Now that you have seen the location of volcanoes, mountain ranges,
and majority of earthquake epicenters, study your Map of Plate
boundaries once more. What do you think are the bases of scientists in
dividing Earth’s lithosphere into several plates?

interact. For example, the "Ring of Fire" shows a clear outline of plate
Scientists divide Earth’s lithosphere into several plates based on the
patterns of earthquakes, volcanoes, and mountain ranges. These
features are mostly found along plate boundaries, where plates meet and
edges due to its many volcanoes and earthquakes.
By studying maps of earthquake epicenters, active volcanoes, and large
mountain ranges, scientists noticed that these features form in specific
zones. This helped them understand that the Earth's outer layer is broken
into moving pieces, or plates. The movement and collision of these plates
explain many of Earth’s surface features and natural events.
