CH5 Sec 5 – Plate Tectonics
1. What is the Theory of Plate Tectonics?
2. What are the three types of plate
boundaries?
II.
The theory of plate tectonics (tek TAHN iks) states
that pieces of Earth’s lithosphere are in slow,
constant motion, driven by convection currents in
the mantle. The theory of plate tectonics explains
the formation, movement, and subduction of
Earth’s plates.
There are three kinds of plate boundaries:
divergent boundaries, convergent boundaries, and
transform boundaries. A different type of plate
movement occurs along each type of boundary.

Tectonics”. Turn in by 24 NOV (Monday) for credit.

(20 min) Big Idea: “How Earth’s crust changes over time”
How Does Plate Movement Generate Earthquakes? (1:42) TechBook
Fault Lines, Stress & Earthquakes (3:38) From “Earthquakes: Our Restless Planet”
In class – students should write and answer following questions in notebooks:
CH6 Sec1 – Forces in Earth’s Crust
1. How does stress in the crust change the
Earth’s surface?
2. What land features result from the forces of
plate movement?
III.
Three different kinds of stress can occur in the
crust—tension, compression, and
shearing. Tension, compression, and shearing
work over millions of years to change the shape
and volume of rock.
The forces produced by the movement of Earth’s
plates can fold, stretch, and uplift the crust. Over
millions of years, the forces of plate movement can
change a flat plain into landforms such as anticlines
and synclines, folded mountains, fault-block
mountains, and plateaus.

Wed – CH6 Section 2: Earthquakes & Seismic Waves
I.
(10 min) Big Idea: “How do scientists measure Earthquakes?”
Seismology & Earthquakes (3:23)
In class – students should write and answer following questions:
CH5 Section 2 – Earthquakes & Seismic Waves
1. How does energy of an earthquake travel
through the Earth?
2. What are the scales used to measure the
strength of an earthquake?
3. How do scientists locate the epicenter of an
earthquake?
II.
Seismic waves carry energy from an earthquake
away from the focus, through Earth’s interior, and
across the surface.
Three commonly used methods of measuring
earthquakes are the Mercalli scale, the Richter
scale, and the moment magnitude scale.
Geologists use seismic waves to locate an
earthquake’s epicenter. Seismic waves travel at
different speeds. P waves arrive at a seismograph
first, with S waves following behind. To tell how far
the epicenter is from the seismograph, scientists
measure the difference between the arrival times of
the P waves and S waves. The farther away an
earthquake is, the greater the time between the
arrival of the P waves and the S waves

Thur – CH6 Section 4: Volcanoes & Plate Tectonics
I.
(20 min) Big Idea: “Where do volcanoes form?”
How Does Plate Movement Generate Volcanoes? (1:01) Discovery TechBook – Forces That Shape the Earth (Seg. 6 of 18)
In class – students should write and answer following questions:
CH6 Sec 4 – Volcanoes & Plate Tectonics
1. Where are most of Earth’s volcanoes
found?
2. How do hot spot volcanoes form?
Volcanic belts form along the boundaries of
Earth’s plates. At plate boundaries, huge pieces of
the crust diverge (pull apart) or converge (push
together). As a result, the crust often fractures,
allowing magma to reach the surface. Most
volcanoes form along diverging plate boundaries
such as mid-ocean ridges and along converging
plate boundaries where subduction takes place.
A hot spot is an area where material from deep
within the mantle rises and then melts, forming
magma. A volcano forms above a hot spot when
magma erupts through the crust and reaches
the surface. Some hot spot volcanoes lie in the
middle of plates far from any plate boundaries.
Other hot spots occur on or near plate boundaries.

Fri – CH6 Section 5: Volcanic Eruptions
I.
(10 min) Big Idea: “What causes volcanoes to erupt?”
Volcanic Eruptions: http://app.discoveryeducation.com/player/view/assetGuid/AC438ACF6CAD-4F6B-A253-7E94B58C0336
In class – students should write and answer following questions:
CH6 Sec 5 – Volcanic Eruptions
1. What happens when a volcano erupts?
2. What are the two types of volcanic
eruptions?
3. What are a volcano’s stages of activity?
II.
When a volcano erupts, the force of the expanding
gases pushes magma from the magma chamber
through the pipe until it flows or explodes out of the
vent.
Some volcanic eruptions occur gradually. Others
are dramatic explosions.Geologists classify
volcanic eruptions as quiet or explosive. The
physical properties of its magma determine how a
volcano erupts. Whether an eruption is quiet or
explosive depends on the magma’s silica content
and viscosity.
Geologists often use the terms active,
dormant, or extinct to describe a volcano’s stage
of activity. An active, or live, volcano is one that is
erupting or has shown signs that it may erupt in the
near future. A dormant, or sleeping, volcano is like
a sleeping bear. Dormant volcanos should awaken
in the future and become active. An extinct, or
dead, volcano is unlikely to erupt again.
