and your group will then choose one volcano and create a model of that type of
volcano. Find
a picture and description of your volcano and create a list of all of the properties of that
volcano. Do
any additional tasks given to you by your teacher also. Your
volcano model will be evaluated using a rubric made by your teacher. Volcanoes
are considered both a destructive and constructive force of nature. Some are
destructive, some are constructive and some are both. As
a concluding activity make a Venn Diagram that compares all the volcanoes in
regard to destructive and constructive forces. Author 
Introduction
What
Is A Volcano?
A
Volcano
is most commonly a conical hill or mountain built around a vent that connects
with reservoirs of molten rock below the surface of the Earth. The term volcano
also refers to the opening or vent through which the molten rock and associated
gases are expelled.
There
are several different types of volcanoes, each having its own distinct
properties. Some are mild-mannered and constructive while others are
furious, explosive and destructive.
The
Task
Research
why and where volcanoes occur.
Find
out how many different types of volcanoes there are. What are the distinct
properties of each type?. Research their physical properties, history, and
potential for future eruptions.
Why
Do Volcanoes Occur?
Here
inThe
Earth's mantle temperatures are hot enough to melt rock and form a
thick, flowing substance called magma. Lighter than the solid rock that
surrounds it, magma is buoyant much like a cork in water; being buoyant, it
rises.
As
the magma rises,
some of it collects in large reservoirs, or magma chambers that fuel
volcanoes. As the rising magma nears the Earth's surface, pressure decreases,
which causes the gases in the magma to expand. This expansion propels the magma
through openings in the Earth's surface: a volcanic eruption occurs. Once magma
is erupted, it is called lava.
Where
Do Volcanoes Occur?
The
Earth's outermost shell -- the lithosphere -- is broken into a series of
slabs known as lithospheric or tectonic plates. These plates are
rigid, but they float on the hotter, softer layer in the Earth's mantle. There
are 16 major plates. As the plates move about, they spread apart, collide, or
slide past each other. Volcanoes occur most frequently at plate boundaries.
Volcano
Types
Volcanic eruptions range from quiet outpourings of lava to violent earth-shaking
explosions! The different type of volcanic eruptions and explosions
produce different types of volcanoes. Each type is named for its
structure.

You
may create a 3-D model or a computer animation of an eruption of your volcano.
