Topo Maps and Satellite Views: TEKS 8.9C
To the teacher:
• This CPO Science PowerPoint presentation is designed to guide you
through the process of presenting the lesson to your students. The
presentation uses a 5-E teaching model: Engage, Explore, Explain,
Elaborate, and Evaluate.
• The PowerPoint Slide notes indicate where you may want to bring in
various lesson elements such as quizzes, readings, investigations,
animations, and practice materials. Additional science background
information is provided in the slide notes where appropriate. You can
view these notes by selecting “View,” then “Normal.” You will see the
notes pane at the bottom of the PowerPoint workspace. Additionally,
the slide notes are available as a separate document, accessible from
the lesson home page.
• The slides that follow are intended for classroom use.

Maps and views of Earth
• Topographic or “topo” maps and
satellite views of Earth are ways to
see and study Earth’s surface
features.
• Carve a potato into “Spud Mountain”
as shown here. Photograph the
potato from above and then create a
topo map of it. Compare and contrast
the “satellite view” and topo map of
Spud Mountain.

Time to investigate!

Erosion and Weathering
• Erosion is the process of moving sediment by wind, water,
ice, or gravity.
• Weathering is the process of breaking down rock and
minerals. Weathering is caused by the Sun’s energy, wind,
running water, ice, chemical reactions, and the actions of
organisms.
• You created a topo map of a model land surface. Imagine
that the mountain in the model is a volcano. Predict how
it will it be affected by erosion and weathering over the
next 1 million years. What erosional features will you see?
How might weathering reshape these?

Did your prediction look like this?
• Ship Rock in New Mexico is an
ancient volcano. All that remains
today is a volcanic neck. A volcanic
neck is solid magma that was in
the main vent.
• Weathering has broken down the
rock and erosion has removed most
of the sediment surrounding the neck for
more than 20 million years.
• What would a topo map and a satellite view of this land
feature look like? Sketch your answer.

Time for Practice!
• Complete the lesson practice activity
- Topographic Maps
• Find a satellite view of Ship Rock on
the Internet. Does it look the way you thought it
would? Which features seem to be evidence of
erosion? Which features seem to be evidence of
weathering?

Show what you know!
• Try the lesson’s interactive quiz, or complete a quiz
that your teacher can print out for you.
• Hint:
– You might want to review your lesson reading piece one
more time before trying the quiz.
