The Earth’s Changing
Surface
Weathering and Erosion
What is weathering?
Weathering is the breaking
down of rocks into smaller parts
by plants, chemicals, frost, and
changes of temperature.
What is erosion? Erosion
includes weathering and also
the transporting of weathered
material from one place to
another by running water, wind,
and glaciers.

1. What is erosion?
Erosion is a natural process where the earth’s surface gets broken down.
2. What causes erosion?
Erosion is caused by natural elements such as weather (wind, rain, snow,
etc.) and water movement.

3. What is weathering?
Weathering is the breaking down of materials contained in the earth’s
crust into smaller pieces, called sediment.
4. What are two types of weathering?
Two types of weathering are physical weathering and chemical
weathering.
Soil and Its Makeup
What are the different layers of soil?
Before I did my
research, I only
knew the names
of the different
layers of soil…
Graphic Organizer: Inspiration
After I did my research using
this really cool Filamentality
website:
http://www.kn.att.com/wired/fil/pages/listearthslo1.html
in addition to some other
websites, I learned a lot more
about the different layers of
soil!
Volcanoes
Let's make a virtual volcano!
What is an Earthquake?
An earthquake is the shaking,
rolling, or sudden shock of
the earth’s surface.
PET Manipulative:
Earthquakes
Ball and ramp game
What angle should the ramp be at in
order to have the ball travel three feet
(90cm) before and after an earthquake?
Hypothesis anyone?
I think that the bigger the
angle of the ramp, the
further the ball will travel.

“Rock Groups”
Sedimentary: Rocks that are broken down by
weathering and deposited in layers in the rivers, lakes,
and oceans.
Metamorphic:
Rocks that are squeezed and
changed by heat and pressure in the earth.
Igneous:
solidified.
Rocks made from molten rocks that
Filamentality
We designed our Filamentality website in order to give
students the opportunity to browse additional resources
related to our unit of study, The Earth’s Changing Surface.
We included videos, songs, games, and informational
pages, just to name a few!
