1. Good day Class!

2. REVIEW

3. Plate Tectonics
The theory that the Earth’s outermost layer is
fragmented into a dozen or more large and
small plates that move relative to one another
as they ride on top of hotter, more mobile
material.

5. What Are Tectonic Plates?
•A plate is a large, rigid
slab of solid rock.
–Plates are formed from
the lithosphere: the crust
and the upper part of the
mantle.
•The plates include both
the land and ocean
floor (Continental and
Oceanic Plate).

6. LEARNING OBJECTIVES:
•a.) Define and Differentiate the three types of plate boundaries.
•b.) Create a 3D Model of the three types of Plate Tectonic
Boundaries
•c.) Value the importance of studying the types of plate tectonic
boundaries

7. PRE-ACTIVITY
In your own words, describe the following
images.

9. What Drives Plate
Tectonics?
•The slow movement of hot,
softened mantle lies below
rigid plates.
•The hot, softened rock in the
mantle moves in a circular
manner in a convection flow

12. Earth’s Plates

13. Movement of
the Plates
Over Time
Permian
248 million years ago
Triassic
206 million years ago
Jurassic
206 million years ago
Cretaceous
65 million years ago
Present Day

14. Different Types of
Boundaries

16. Different Types of
Boundaries
•Divergent boundaries spread apart
–Places where new crust is generated as the
plates pull away from each other
–New crust is created from magma
pushing up from the mantle

18. Different Types of
Boundaries
•Convergent boundaries
(come together)
–Places where crust is destroyed as
one plate dives under another.

21. Different Types of
Boundaries
•Transform boundaries (slide
against each other)
–Places where crust is neither
produced nor destroyed as the
plates slide horizontally past each
other

23. Consequences of Plate
Tectonics
•Earthquakes and volcanic activity are linked to plate
tectonic processes.
•The Ring of Fire is the most seismically and volcanically
active zone in the world.

24. Consequences of Plate
Tectonics
The San Andreas Fault –a
transform fault
Aerial view of the area around Thingvellir, Iceland,
showing a fissure zone (in shadow) that is an on-land
exposure of the Mid-Atlantic Ridge. Right of the fissure,
the North American Plate is pulling westward away from
the Eurasian Plate (left of fissure).

25. DO YOU HAVE ANY QUESTIONS?

26. GROUP ACTIVITY

27. GROUP ACTIVITY
You will going to re-enact the movement of the different
plate boundaries that we have discussed.
•GROUP 1: DIVERGENT BOUNDARIES.
•GROUP 2: CONVERGENT BOUNDARIES
•GROUP 3: TRANSFORM BOUNDARIES
You only have 5 minutes to do the activity and then you will
present it later.

28. INDIVIDUAL ACTIVITY
DIRECTION: Using a Venn
diagram, compare and contrast the
different types of plate boundaries.

29. ASSIGNMENT
Bring the following materials:
•Cookie biscuit (Oreo, hansel,
presto, bingo)
•Long bond paper
•Markers
