Q
How did the Graham cracker model represent convergent boundaries?
A
The crackers were pushed toward each other.
Q
What happened when crackers were pushed together?
A
They could buckle, fold, or one could move beneath another.
Q
How did the model represent divergent boundaries?
A
The crackers were pulled apart, creating a gap.
Q
How did the model represent transform boundaries?
A
The crackers slid past each other.
Q
What did sliding crackers demonstrate?
A
Friction and sudden slipping, similar to earthquake-producing faults.
Q
Which cracker model best explains mountain building?
A
Convergent boundaries.
Q
Which model best represents seafloor spreading?
A
Divergent boundaries.
Q
Which model best represents an earthquake-producing fault?
A
Transform boundaries.
Q
What are the limitations of the Graham cracker model?
A
It cannot accurately reproduce real plate temperatures, pressures, rock strength, sizes, or timescales.
