A student designed an experiment to demonstrate the movement of Earth plates. The steps of the experiment are listed below. - Make a vertical slit in the middle of a cardboard piece.

- Fold and place two pieces of paper inside the slit and tape two blocks of cardboard labeled Earth plate on top of the paper as shown below.

- Pull down the papers below the slit.

- Observe the direction of motion of the Earth plates.

The student's experiment most likely demonstrates how

volcanoes subside

faults are created

rift valleys are created

mountains are formed
