Rogue waves are known to reach heights of about one hundred feet high. That is about four two-story houses. In the article, it states that “The surrounding sea can appear calm when suddenly a 100 foot tall wave comes crashing towards you.” Scientists are not one hundred percent certain why these waves are as high as they are. Ocean depth, currents, wind and island presence could affect the height. In conclusion, rogue waves and their height are caused by many things, including wind, ocean depth, and island presence. Similar to rogue waves, tsunamis are caused by factors that may not be first to be thought of, and these factors severely affect their appearance. Most of the time, tsunamis are caused by earthquakes underwater. Stated in the article, “Once water is moved by an earthquake or another event, large waves like ripples spread out from the point where the water was first moved,” (Tsunamis by Earth Science For Kids, Ducksters.com pg 1). The gap created in the sea floor, or the underground movement, affects the water on the surface, creating ripples that turn into a series of waves that travel very quickly for long distances until they reach
