 Katie designed an experiment using a paint roller pan, sand, and water. The steps of the experiment are listed below. 
 Put 3 inches of moist sand on a paint roller pan.
 Make a beach by scooping the sand toward the higher portion of the pan.
 Form hills of sand to mimic dunes.
 Add toothpicks to the sand dunes to represent sea oats and vegetation.
 Pour water into the deeper end of the pan.
 Katie's experiment most likely represents the interactions between the
 atmosphere, biosphere, and geosphere
