Web. 13 Sept 2012. http//environment. nationalgeographic. com/environment/natural-disasters/tsuna mi-profile/ This electronic source was helpful to me by providing me with even much background information on tsunamis and their effects. In addition, a video on National Geographic allowed me to billet a real tsunami in action. 4.Luhr, James F. Earth. Smithsonian. Smithsonian Institution. New York, New York DK Publishing, 2003. Print. (P. 123, 143, 151, 190, 192, 271, 429, 501) This printed source helped me understand the different things that can cause a tsunami. This includes a signifier of submarinal conditions, and-although this is rare- those reasons related to meteors. 5. Cramer, Deborah. Ocean. Smithsonian. Smithsonian Institution. New York, New York Collins Publishing, 2008. Print. (P. 62) This printed source was very helpful, because it showed me a tsunamis effect on the whole ocean.This is an important thing to note, becaus e it helps put into emplacement how a tsunami is not only devastating once it hits shore, but also before it hits shore and is still a violent wave uncontrollably speeding crosswise the ocean toward the shore, destroying almost everything in its line. Materials 1. Plastic shop recess (at least 40 cm long x 5 cm deep) 2. Source of water 3. Small gravel or pebbles (to be spread over bottom of fund stripe as type of an uneven bottom in the ocean) 4. Piece of wood (2 in recondite x 4 in wide x 8 in long) 5. Sharpie permanent marker 6. Metric ruler 7. Digital stopwatch . Bright ceiling light (above location of experiment) 9. Hand towel 10. tender to run stopwatch 11. Lab notebook computer 12. Graph Paper agency 1. Find a well-lit location at which to execute experiment (favorably deep down and free of commotion) 2. Remove any items away from location that could be discredited by potential splashing water from storage corner 3. adjust storage box on white sheet and under lum inous ceiling light with no surrounding lights in order to define waves as clearly as possible 4. Cover bottom of storage box with layer(s) of gravel/pebbles as needed until bottom of box cannot be seen 5.Fill storage box with a few centimeters (cm) of water 6. Draw handsome line with sharpie on a shorter end of the boxs exterior, approximately 2. 5 cm below rim of box (this label the spot from where piece of wood will be dropped) 7. Begin practicing do and tracking waves 8. Line up bottom of wood at attach line and drop, immediately thereafter watching for resulting wave traveling from atomic number 53 end of tank to the some other 9. Begin executing real experiment once comfortable creating and tracking waves 10. evacuate/fill water tank after practice runs until 1 cm of water is left in tank. Use metric ruler for accuracy.This water reasonableness will be used as the measurement for the first treatment 11. Create permit data table in lab notebook 12. Notify pop the que stion with stopwatch when they should start and stop timing the waves path (those times should be as soon as wooden block is dropped and wave is formed, and as soon as wave returns and hits other end of box) 13. Record the time in data table from lab notebook 14. Repeat step 11 nine more times (nine more tests), always waiting for water to settle before dropping wood again from consistent position each test 15. Fill box with water depth 2 cm (confirm with ruler) 16. Repeat steps 11-13 17.Fill box with water depth of 3 cm (confirm with ruler) 18. Repeat steps 11-13 19. Empty box and repeat steps 9-16 four times so that end result is 5 trials (10 tests per trial) for each of the 3 depths 20. Analyze data for each water depth for each trial across the 10 tests and eternize data in notebook 21. Average time data across the three trials from the numbers calculated in step 19 22. mensuration and record distance between where wave was created (leading edge of mark from where wood was dro pped) and other end of box 23. Divide distance by bonnie time it took for wave to move from one end of tank to the other for each water depth.The answer recorded in notebook will be wave velocity 24. Plot data (x-axis=water depth, y-axis=wave velocity) 25. Answer the following questions What is the relationship between the water depth and the wave velocity? Is it a linear relationship? Does the wave velocity augment or decrease with increasing water depth even with an uneven bottom? Does this result make sense to you according to the research that you have done on tsunamis that seems to state that, in general, if the level of the water is higher then the velocity of the wave will be greater? If it does not match, then the conclusion should be that an uneven bottom does affect the velocity of tsunami waves. 26. equality 1, below, shows the mathematical relationship between the wave velocity in shallow water as a function of water depth. Equation 1 states that velocity is the squar e root of the product of the acceleration of gravitational force and the water depth V = vgd V = Velocity in meters/ fleck (m/s) g = Acceleration of gravity (9. 8 meters/second2) d = Water depth in meters (m) 27. Using equation 1, plot wave velocity as a function of water depth. How does the plot compare to results from the storage box/model-tsunami?
