question 8 of 28
why might scientists use a model to show the movement of the continents?
a. the actual movement is too complex.
b. the actual movement is too slow.
c. the actual movement is too dangerous.
d. the actual movement is too fast.

Explanation:

Continental movement occurs over geological time scales. For example, the rate of plate tectonics (which causes continental movement) is typically a few centimeters per year. This is extremely slow on a human - observable time scale. A model can be used to speed up the visualization of this slow process so that it can be better understood.

Answer:

B. The actual movement is too slow.
