10. TYPES OF PLATE BOUNDARIES

11. DIVERGENT BOUNDARY
Plates move apart, creating a zone of tension.
Seafloor spreading - As the plates separate, new
materials from the mantle ooze up to fill the gap.
These materials will slowly cool to produce new
ocean floor.
Rift valleys – down faulted valleys. It happens
between continents.
 Rising of Magma

12. CONVERGENT BOUNDARY
Two plates are moving toward each other.
Main Processes:
Subduction zone - if one plate moves underneath
the other.
Orogenic Belt - if the two simply collide and
compress

16. TRANSFORM FAULT BOUNDARY
Plates slide or grind past each other.
The immediate concerns about transform
fault boundaries are earthquake activities
triggered by movements along the fault
system

18. VALUES INTEGRATION
Our country is located just right above Filipino
Plate and on the Pacific Ring of Fire where
most earthquake and volcanic activities occur
due to interactions between different plate
boundaries. Through solidarity, how can we
minimize damages brought about by these
natural disasters? And why is disaster
preparedness everyone’s responsibility?

26. LESSON #1: EVIDENCE OF
PLATE MOVEMENTS

27. OBJECTIVES
1. Enumerate pieces of evidence that support
plate movements;
2. Explain the reasons why Alfred Wegener’s ideas
are generally rejected; and
3. Compare Wegener’s evidence on plate
movements with modern science.

28. CONTINENTAL DRIFT THEORY
Proposed by Alfred Wegener.
The continents were once one large landmass
called as Pangaea. (Gr. All Earth)
It broke into two smaller supercontinent called
Laurasia and Gondwanaland during the Jurassic
Period.

29. EVIDENCE 1: THE CONTINENTAL JIGSAW PUZZLE
WEGENER
• The eastern coastline of South
America and western coastline of
Africa seem to fit snugly to each
other.
TODAY
• South America and Africa fit
together; India, Antarctica, and
Australia match one another;
Eurasia and North America
complete the whole continental
puzzle in the north.

30. EVIDENCE 2: FOSSIL RECORDS
WEGENER
• Similar fossils of plants and
animals were found on the
eastern coastline of South
America and western coast
of South Africa.
TODAY
• Fossils in South America and
South Africa are very similar
in terms of their sequence
and share common
ancestors.

31. EVIDENCE 2: ROCK RECORDS
WEGENER
• The sequence of rock
on opposite sides of
match each other.
TODAY
• Geological studies of areas
with glaciers in eastern
South America match
in South and West Africa.

33. SEAFLOOR SPREADING
In the early 1960’s, scientist Harry Hess, together with Robert Dietz,
suggested an explanation to the continental drift.
According to this theory, hot, less dense material from below the
earth’s crust rises towards the surface at the mid-ocean ridge. This
material flows sideways carrying the seafloor away from the ridge,
and creates a crack in the crust. The magma flows out of the crack,
cools down and becomes the new seafloor. Overtime, the new
oceanic crust pushed the old oceanic crust far from the ridge. The
process of seafloor spreading allowed the creation of new bodies of
water.

35. VALUES INTEGRATION
During the time when Alfred Wegener
presented his ideas about the Continental
Drift Theory, he received a lot of criticism.
But still, Wegener searched for evidences to
support his claim. What Ruizian core values
is shown by the scientist and how will you
apply it in your time as a student?

(POSSIBLE CAUSES OF
MOVEMENT) OF PLATE TECTONICS

42. OBJECTIVES
1. Identify the driving forces of plate movements;
and
2. Identify the resisting forces of plate movements.

43. PLATE TECTONICS THEORY
This theory evolved from the two former theories
and was developed during the first decades of the
20th century. Crustal plates could possibly moved
by two types of forces: the driving forces and
resisting forces.
