Here’s What Your Map
Should Look Like
Let’s Review Our Answers
1 & 2) Both earthquakes and
volcanoes are concentrated in
definite zones.
3) Earthquakes and volcanoes tent to
occur in the same areas
4) The west coast of North America
has the greatest risk of both
earthquake and volcano damage.
Urban planners, engineers, and
builders should use this information
when placing and designing
structures.
Think back to yesterday…
What did we notice about
where volcanoes form?
THE ANATOMY OF A VOLCANO
What’s
This?
Lava collects in the crater, the
bowl-shaped area that forms
around the volcano’s vent.
What’s
This?
The point on the surface where
magma leaves the volcano’s
pipe is called the vent.
Magma that reaches the
surface is called lava
What’s
This?
What’s
This?
Sometimes magma forces
its way out of a volcano
through a side vent.
What’s
This?
The river of
lava that pours
down a volcano and over the
land is called a lava flow.
A pipe is a narrow, almost
vertical crack in the crust
through which magma rises
to the surface
What’s
This?
Magma is extremely hot,
molten material that also
contains dissolved gases
including water vapor
What’s
This?
What’s
This?
As magma rises toward the
surface, it forms a large
underground pocket called a
magma chamber
Please Take out the
Following Supplies:
• 1 Pencil
• Red, Orange, & Brown
Crayons/Markers/Colored Pencils
• 1 Index Card
The Anatomy of a Volcano
• On the back of your handout, you
will draw and label a volcano from
the inside out
– The first thing you should draw is an
east/west line across the bottom of
the page, about 5 cm from the
bottom…It will represent the border
between the crust and mantle.
– You will then draw a cone shape to
represent the slopes of the volcanoes
sides.
– Use the key words below to help you
determine where to draw the interior
parts of a volcano:
Pipe…Vent…Side Vent…
Magma Chamber…
Magma…Lava Flow…Crater…Lava
Don’t forget to name your volcano!
Once your sketch is
complete…
On your Index Card, please write:
• Your First and Last Name
• 6-1/6-2
…Use your imagination and prior
knowledge about volcanoes to answer the
following questions!
…BE CREATIVE!
1. How did the volcano behave the day
before the eruption?
2. Describe how the volcano reacted during
the eruption
3. What did the area surrounding the
volcano look like after the eruption?
(HINT: Think of the video we watched in class
about the lifespan of a volcano…Think of
how it changed as time progressed…)
HOMEWORK
• Complete your volcano diagram
and attach your index card(s) with
your responses to questions 1-3
• Read pages 183-185
Please do not complete your
reading until you’ve finished your
