A student places an open hardcover book face down on a table. Slowly, he pushes the two halves of the book toward each other. Which geologic process is he trying to model?
a. mountain building
b. sediment deposition
c. sea-floor spreading
d. divergent plate boundaries
The answer would be letter A, a mountain building. The two surfaces of the book signify the tectonic platesAs he presses them in the direction of each other he is demonstrating a convergent boundary, and mountains are an effect of convergent plates.
When the student pushes the two halves of the book toward each other, the book is likely to rise at the spine. This model is an attempt to illustrate the process of mountain building.
