Use your observations from yesterday to help you answer the questions
We used three things yesterday to build and use a model of how the continents move. Here is what each piece of the model represented.
Graham cracker: Thick crust
Fruit Roll-up: Thinner crust
Frosting: The top of the mantle
Look at your observations for Part 1 to answer the next few questions.
Were the continents getting closer together or farther apart?
As the continents move apart something forms between them, what do you think that is?
As you moved the pieces closer together one of the crumpled up. Which kind of crust crumpled?
In real life the thinner crust also gets pushed under the thick crust and down into the mantle. What do you think happens to it?
Before the two pieces of crust collided there was an ocean between them. What do you think happened to the ocean?
The two pieces of crust crumpled when they collided. Why?
When the crust crumpled it formed some land features. Which kind of land feature did they make?
