Tectonics and Natural Disasters
Collect data, map, and describe patterns in the locations of volcanoes and earthquakes related to tectonic plate boundaries, interactions, and hotspots.
Science and Engineering Practice(s)
Construct Explanations, Argue from Evidence,
Analyze & Interpret Data, Obtain and communicate information
Crosscutting Concepts
Cause and Effect, Stability and Change
I Can Statement
...I can identify patterns about the locations of volcanoes and
earthquakes and describe how these natural disasters are
connected to tectonic processes.

2. Online Activity Do research. Make graphs. Interpret seismic data
Click on the following link.
Link:
On the right side of the USGS website,
find the “Past 7 Days” heading. Select
the “All Earthquakes” link. A data table about earthquakes will appear.
Select “All Earthquakes”
B) Use this data to create a bar graph about the 10 most recent earthquakes in Alaska. Use the Kid’s Zone website to help you.
Link: Kid's Zone-Create a Graph Website
C) Interpret the data in your graphs.
1) Which data did you choose to graph and why?
2) Explain what the data represents.
3) Get ready to share.

3. Answer these questions.
Get in pairs. Do online research. Get ready to share.
Science and Engineering Practice(s)
Obtain and communicate information, Construct Explanations
1) What was the general latitude and longitude for these
ten earthquakes?
2) What was the average magnitude for these ten earthquakes?
3) Where in Alaska did these earthquakes occur?
4) Why did these earthquake occur in Alaska?
5) What determines the power (magnitude) of an earthquake?
6) What tectonic factors cause earthquakes?
