Volcanic

1. VOLCANO,
EARTHQUAKES, AND
MOUNTAIN RANGES

2. WHAT ARE THE LAYERS OF EARTH?
CRUST
MANTLE
CORE
The outermost layer of the earth
Middle layer of the earth,
made of molten rocks
Innermost layer of the earth

3. Can you identify this Landforms?
Sierra Madre

4. Mayon Volcano

5. Have you ever wondered why our
country is endowed with this kind of
geologic Features?

6. We will study and understand how
And why several features of the
Earth continuously change.

7. LITHOSPHERE
The rigid outer part of the earth,
Consisting of the crust and the
upper mantle.
Hard
brittle

8. Plate tectonic
 Earth’s lithosphere consist of layers,
the crust and the upper part of the
mantle.

9. According to the plate tectonic model,
the entire lithosphere of the Earth is
broken into numerous segment called
Plates.

10. The Crust
Made up of a variety of solid rocks
like sedimentary, metamorphic , and
igneous rocks.
The outermost , coolest layer of the
earth

11. Types of Crust

12. Continental crust
Thicker
less dense than oceanic crust
Oceanic crust
Thinner
Denser that continental crust

13. Continents of the world
NORTH
AMERICA EUROPE ASIA
AFRICA
SOUTH
AMERICA AUSTRALIA
ANTARTICA
Which continent can you
Find Philippines?

14. Tectonic Plate
The plates move very slowly
but constantly

15. Plate tectonic theory
The Earth’s crust is broken into
segment (Plates) that moves slowly
constantly (tectonics)
What if the plates are moving?

16. What are the effects of plates movement?
Earthquakes
Formation of volcanoes
Formation of mountains /Mountains
ranges

17. Earthquake

18. Earthquake
Sudden and violent shaking of the
ground. Sometimes causing great
destruction , as a result of movement
within the earth’s crust or volcanic
action

19. A weak point in the tectonic
Plate where pressure within
The crust is released
origin

20. Where do earthquakes usually
happen?
Earthquakes may happen anytime,
either on land or under water.
Earthquake on land can cause either
tectonic plates movement or volcanic
eruption.

21. Earthquake under the sea can
cause tsunami.
Earthquakes usually happen along
the edge of plates( plates
boundaries)

22. The crust and a part of upper
mantle make up the
Lithosphere.

23. There are two kinds of
crust
Continental crust
Oceanic crust
Thicker but less dense
Thinner but denser

24. Plate Tectonic theory
Which suggest that earth’s crust
Is made up of plates that
constantly move
in various ways, thus producing
Earthquake, mountains volcanoes And
other features
and interact
