Lesson Goal
I will explain plate tectonic
theory including uplift,
volcanoes and earthquakes. I
will demonstrate knowledge
in my science notebook with
definitions, illustrations, and
question responses.
Our Changing Earth
So far, we have learned some ways
the Earth changes naturally:
Weathering
Water Erosion
Wind Erosion
Extreme Weather
Our Changing Earth
This week, we will learn another way the
Earth changes naturally:
Plate Tectonics
Let’s add this topic to our notebook
(Don’t forget the Table of Contents)
Plate Tectonics
Let’s start with some new science words
to add to our notebook:
Write Vocabulary under the title
Plate Tectonics, where we will be
adding some new words as go
Core:
the solid rock, very hot center
of the Earth
Mantle:
the layer of hot rock beneath
Earth’s surface
Crust:
the outside, hard layer of the
Earth
Diagram
Draw the diagram in your notebook. Be sure to
label the parts we learned.
Inside the Earth 1
Inside the Earth 2
Inside the Earth
Check for Understanding
Discuss with your table group
On your note card, answer:
1. On which layer does erosion and
weathering occur on Earth?
I wonder how Earth’s layers relate
to plate tectonics?
Notes
 Earth’s crust is broken into pieces,
which “float” on the mantle layer
 These pieces, called plates, are always
moving, but very slowly
 The plates move apart, collide into one
another, and slide against other plates
We’re going to need more vocabulary words
Magma:
melted rock
found between
the crust and
mantle
Tectonic Plates:
massive pieces of rock under
the land that fit together like a
giant puzzle
Continental Drift:
when tectonic plates move,
causing Earth’s continents to
move with them
Plate Tectonics
Continental Drift
Check for Understanding
Discuss with your table group
On your note card, answer:
2. What was Pangea?
Continental Drift
Check for Understanding
Discuss with your table group
On your note card, answer:
3. What caused Pangea to break
apart?
I wonder why this is important to
Earth’s surface?
Notes
 When tectonic plates collide, it creates
mountains and volcanoes
 When tectonic plates move apart,
ocean valleys are made
 When tectonic plates slide against each
other, earthquakes happen
We’re going to need more vocabulary words
Fault:
the place where
two plates touch
Uplift:
when plates collide and one is
pushed upward, creating a
mountain
Folding:
when a plate is
squished
between other
plates and
pushes up to
form a mountain
Mountains
Inside the Earth
Check for Understanding
Discuss with your table group
On your note card, answer:
4. Name two ways mountains are
created with plate tectonics
Lava:
when magma
reaches the
Earth’s surface
Volcano:
a mountain
formed by
cooled lava
from Earth’s
mantle
Volcanoes
Diagram
Draw the diagram in your notebook. Be sure to
label the parts.
Earthquake:
when energy in the Earth
causes plates to shift
quickly
Epicenter:
the place
where an
earthquake
began
Magnitude:
how powerful
an earthquake
is
Earthquakes
Plate Tectonics
Check for Understanding
Discuss with your table group
On your note card, answer:
5. Name 3 ways plate tectonics
creates landforms on Earth.

Tsunami:
A huge wave
caused by an
underwater
earthquake or
volcano
Tsunamis
Volcanic Island:
An island
created by the
continual
eruption of a
volcano
Volcanic Islands
Types of Volcanoes
