Tectonic Plate

What is it? (definition)

What’s it like?

Surprising

Fact!

What are some examples?

Type of Movement

Is crust created or

destroyed?

Change in elevation?

Note any other important features or interesting characteristics of the three types of tectonic plate interactions at

boundaries:

Divergent Convergent Transform

Look back at page 92 to see the plate boundary lines. Based on what you have learned so far, describe one location

where you believe that each type of plate boundary is. Explain your reasoning.

Divergent:

Convergent:

Transform:

Tracking Tectonic Plate Motion (Pg. 102)

Write a brief (2-5 sentence) summary of the main ideas:

Science, Technology, and Society: Living on the Mid-Atlantic Ridge (Pg. 116)

What geologic features/dangers exist in Iceland?

What is happening to the tectonic plates that is creating those features/dangers?

How are the people of Iceland able to use those features to help them live well?

Scientific Debate: Continental Drift (Pg. 117)

Give at least two examples of evidence that suggested to Wegener that the continents were “drifting.”

Why didn’t other scientists of his day believe him?

Why do scientists believe him now?
