| | Abstract | Tsunamis are huge waves that can cause a lot of damage to cities, and |
| | can kill many people. They can travel very fast and leave people with little |
| | time to prepare and get away from where the tsunami will hit. They can |
| | cause great damage to cities that can take a long time to rebuild. Can the |
| | shape of the ocean floor affect the size of these huge waves? A tsunami |
| | created by a landslide can be simulated using a tank and gravel dropped |
| | down a slope. Using this it is possible to test if the ocean floor really does |
| | affect the size of a tsunami. Flat, sloped, valley, one hill, two hill, and three |
| | hill ocean floors were tested. Five trials of each sea floor type were done, |
| | and the results were surprising. Tsunamis are affected by the sea floor’s |
| | shape, and that can contribute to why some areas have been known to |
| | have huge tsunamis. The tsunami starts out small and as the water gets |
| | shallower pushes on the sea floor causing it to grow taller and become |
| | this huge destructive wave. As the Tsunami is pushing down on the sea |
| | floor its shape can affect how large the tsunami is. |
