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 towards the higher portion of the pan.
put some soil with very small plants growing on it on the sand.
pour water into the deeper end of the pan.
move the roller pan to create wave like motion in the water.
observe how the sand and plants are displaced by the waves.

Explanation:

Biosphere is the plants.

Hydrosphere is the water on the deeper side of the roller pan.

and the geosphere is the land moving because of the water hitting the land (causing erosion)

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
