*3-D Plate Tectonics Models are due Thursday. Your group should be ready to put the final model together starting at the begining of class. This should not take more than 20 minutes. Your group should not plan on doing any major coloring or construction of parts on Thursday - you should be ready to assemble the final model.*
AGENDA:
- Work on 3-D Plate Tectonics Models
HOMEWORK:
- Do any work needed on your plate tectonics models.
- Complete any notebook work for this unit that is not yet done.
- STUDY the questions for the plate tectonics models. You will be asked 3 of these questions (for the type of model your group has made) so be ready for all of them!
QUESTIONS FOR PLATE TECTONICS MODELS:
Convergent
Boundaries Questions:
1.
What types of lithosphere are found at this
plate boundary and what are they made of?
2.
What is oceanic lithosphere made of and how is
it created?
3.
Why does oceanic lithosphere sit on top of the
asthenosphere?
4.
What is continental lithosphere made of and how
is it created?
5.
Why does continental lithosphere sit higher on
the mantle than oceanic lithosphere?
6.
Why does the oceanic lithosphere go down into
the mantle and what is this called?
7.
What is the Benioff Zone and what does it tell
us?
8.
What is a trench and how is it formed?
9.
What is an accretionary prism and how is it
created?
10.
Why does the lithosphere melt at convergent
boundaries?
11.
How do magma plutons form and what will happen
to them over time?
12.
Why are there volcanoes at convergent
boundaries?

away from a mid-ocean ridge and what does it show us?
