Tsunamis: Ocean and Wave Shape Changes

6 05 Tsunami Nicolai Kortendick 1. The web send presents extensive information regarding tsunamis. Survey the site. A. consume the five facts ab out(p) tsunamis that were the approximately interest or surprising to you. Make a joust of your facts. 1. A tsunami is made up of a series of traveling marine swings of extremely tenacious windlength. 2. They are triggered by earthquakes and underocean volcanic eruptions and deep sea landslides. 3. The ruffle shape changes and the height increases as it approaches the glideline. . Far field tsunamis have a long travel time so it is easier to predict their effects. 5. Near field tsunami have a travel time of mavin or two hours, making it harder to empty people to safe, high areas before the tsunami reaches the bound. B. straightaway port over your list. In your opinion, what is the most intriguing item on your list? Explain. The most intriguing item on the list to me is that tsunamis resemble thrills that I cypher a lot eve ry twenty-four hours and they have extremely long driftlengths. 2.If you were on a ship at sea, and a tsunami passed under your ship, what would probably be your response? Explain. I would be pretty panic-struck if I knew it was a tsunami, and I would be worried for the people on the coast it was heading for. It probably wouldnt be a very big wave if I was far out in the ocean so it wouldnt scare me as much. 3. The site offers a tsunami quiz. get word the quiz. What was your score? I got 7 out of the 10 questions correct. 4. When you viewed the Introduction to Waves video, you learned some(prenominal) terms that apply to all waves.How do the following terms apply to tsunamis and what are typical values for a tsunamis wavelength and amplitude? Use the following sites to look for answers http//www. enchantedlearning. com/subjects/tsunami http//hyperphysics. phy-astr. gsu. edu/HBASE/Waves/tsunami. html C. Wavelength Tsunamis have an extremely long wavelength (which is the distan ce between the point of adept wave and the crest of the next wave) up to several hundred miles long. D. amplitudeThe amplitude of a wave is the height of a wave from the still water level to the upper side of the wave crest. As a tsunami reaches a coastline its amplitude increase greatly. E. crest The crest is the top of a wave. The wavelength of a wave is measured from the crest of one wave to the crest of another. F. trough The trough is the nates of a wave. As a tsunami approaches the coast (where the sea becomes shallow), the trough of a wave hits the beach floor, causing the wave to easy down, to increase in height and to reducing in wavelength.
