The document is a self-learning module that describes plate tectonic theory and the distribution of active volcanoes, earthquake epicenters, and major mountain belts. It includes pre-tests and post-tests for students to assess their understanding. The key points are that plate tectonic theory states the lithosphere is made up of plates that move and interact at boundaries, and that volcanoes, earthquakes and mountains are located near these plate boundaries as a result of the interactions between plates. Students learn about the distribution of these features and take quizzes to relate this to plate tectonic theory.

is used to determine
the earthquake
epicenter using a
distance information
from three seismic
stations.

15. Plate Tectonic Theory
The theory of plate tectonics
states that the Earth’s solid
outer crust, the lithosphere,
is separated into plates that
move over the
asthenosphere, the molten
upper portion of the mantle.

17. Basic Plate Tectonic Concepts
•Earth’s crust and the uppermost layer of the mantle
are composed of rigid units called plates.
•The movement of these plates is small, in the order
of millimeters per year.
•Large-scale geological activities occur on or near
plate boundaries.
•Areas farther from plate boundaries are less prone to
earthquakes.

18. Basic Plate Tectonic Concepts
•The Philippine Sea plate,
which is oceanic, moves
northwestward, ranging from
as fast as 102 mm/year down
around 54 mm/year.
•Most of the Philippine
islands don’t lie on top of the
Philippine Sea plate but on
the Sunda Plate.

19. Major Key Concepts
•The volcanoes, earthquake’s epicenter, and
major mountain belts are distributed in close
proximity of the borders of the tectonic
plates. Once tectonic plates moved in any
possible motion, it could create changes
leading to geologic features and events.

20. Major Key Concepts
•Most of the active volcanoes nowadays are
found in the so called “Pacific Ring of Fire”
which is practically the border of the Pacific
Tectonic Plate.

21. Pacific Ring of Fire
• Argentina
• Belize
• Bolivia
• Brazil
• Brunei
• Canada
• Colombia
• Chile
• Costa Rica
• Ecuador
• East Timor
• El Salvador
• Micronesia
• Fiji
• Guatemala
• Honduras

• Kiribati
• Malaysia

22. Major Key Concepts
•The earthquake epicenters are not found
only in a specific place, but they are found
everywhere where there's a border between
two or more tectonic plates. It doesn't
matter if they collide, move away from each
other, or subduct, the earthquakes will be
there.

23. Major Key Concepts
•The major mountain belts are found in
places where tectonic plates of the same
density collide, so instead some of them go
and be subducted, they push against each
other and lift the area up.
