Progressive waves move along the sea surface. In other words, as this increases, there is a deeper reach of wave base. Introductory Geology Water 5.11 Student Responses 1. when the rate of discharge exceeds that of recharge. The result is amplification of the wave size which can lead to flooding. As waves enter shallow water their wavelength shortens and their height increases. Waves Entering Shallow Water [ home port | lectures | D. jetty Geology Exam 3 Flashcards | Quizlet Tsunamis Wave Orthogonals (Figure 7-8) B. smaller draining area Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) Life History of Ocean Waves (Cont.) Progressive waves move along the sea surface. Sudden shifting of the ocean floor due to earthquakes, volcanic eruptions, and submarine slumping. Internal Waves Constructive wave interference occurs when several wave crests or troughs coincide. Wave Refraction (Figure 7-8a) Destructive wave interference occurs when the crest of one wave coincides with the trough of another wave resulting in a cancellation. - Celerity A. gaining stream Wave energy is focused where the lines converge. Chapter 7 Summary Some of the greatest destruction comes from the storm surge or extreme high water levels due to the: Wave Orthogonals (Figure 7-8) Wave energy is defocused where the lines diverge. Destructive wave interference occurs when the crest of one wave coincides with the trough of another wave resulting in a cancellation. Shallow Water Waves (Figure 7-4b) Tsunamis which are seismic sea waves. Breaking is determined by wave steepness Bending of the wave crest as waves enter shallow water. Internal Waves Waves originate in the fetch area. As waves enter shallow water: 239 Surfing Video: Condition Black Internal waves which occur underwater and move along pycnoclines. Standing waves (seiches) do not move horizontally. Sudden shifting of the ocean floor due to earthquakes, volcanic eruptions, and submarine slumping. http://dusk.geo.orst.edu/oceans/waves.html, Wave energy is focused where the lines converge. What is the process involved in the formation of the summer and winter berms? Other Types of Progressive Waves Standing waves (seiches) do not move horizontally. Standing waves can be dangerous due to the phenomenon of resonance. Oscillate back and forth about a node i.e., a fixed point. They occur when water masses slip over one another. In deep water most waves do not interact with the sea bottom and are called deep-water waves. It is due to: Based on the water cycle, all water available to land dwelling organisms including humankind, ultimately comes from where? Waves in the lonely stretches of the open sea are little noticed by anyone but the occasional sailor. Some of the greatest destruction comes from the storm surge or extreme high water levels due to the:
