The Earth
Earthquakes
Earthquakes are the shaking, rolling or sudden
shock of the earth’s surface. Earthquakes
happen along "fault lines" in the earth’s crust.
Earthquakes can be felt over large areas
although they usually last less than one minute.
Click on the link below for more information.
(List five facts from the Fact and Fiction
section).
Volcanoes
A volcano is a mountain that opens downward to a
pool of molten rock below the surface of the
earth. When pressure builds up, eruptions occur.
Gases and rock shoot up through the opening
and spill over or fill the air with lava fragments.

(List five facts from the Volcano Facts section).
Types of Rock
Rocks are the most common material on Earth.
They are naturally occurring aggregates of one
or more minerals.
Click on the link below for more information.
(List the three types of rock and explain how
they are formed).
Weathering
Weathering takes place as rocks are broken down
into progressively smaller pieces. There are
three types of weathering: mechanical, chemical,
and biotic.
Click on the link below for more information.
(Describe the three types of weathering and
provide one example for each).
Erosion
Webster's defines erode as, "To eat into or away
by slow destruction of substance."
Click on the link below for more information.
(Define erosion in your own words. List three
land forms created by erosion).
Constructive Processes
(Deposition)
Constructive processes help the Earth. Click on
the link below to discover how beaches, sand
dunes, and deltas are formed.
(Describe how each are formed. Name a delta
found in the United States.).
