Katie designed an experiment using a paint roller pan, sand, and water. the steps of the experiment are listed below. 1. put 3 inches of moist sand on a paint roller pan. 2.make a beach by scooping the sand towards the higher portion of the pan. 3.put some soil with very small plants growing on it on the sand. 4.pour water into the deeper end of the pan. 5.move the roller pan to create wave like motion in the water. 6.observe how the sand and plants are displaced by the waves. katie’s model most likely represents the interactions between the a. atmosphere, ocean and cryosphere b. geosphere, ocean, and biosphere c. atmosphere, ocean, and biosphere d. cryosphere, biosphere, and ocean

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
