Chapter 7 Summary Interaction with the sea bottom. D. the open spaces between clay particles in a very impermeable rock A. exactly 12 hours When wave passes, no net displacement of water. - Destructive Waves are disturbances that are generated on or beneath the sea surface. During the spring tide, the Moon, Sun, and Earth would exist in a same straight email prof. ] email prof. ] surf | Resonance because the moon orbits around the Earth in the same direction the earth rotates, it takes more time for the same point on the earth to be beneath the moon over the lunar day. Course Hero is not sponsored or endorsed by any college or university. Wind-generated waves are progressive waves because they travel across the sea surface. They have very long periods and very large heights. Transformation of Shallow-water Waves (Figure 7-7b) The result is amplification of the wave size which can lead to flooding. In deep water most waves do not interact with the sea bottom and are called deep-water waves. Suddenly one person gives a jerk to the rope. Chapter 7 Summary Adding water to materials on a slope can reduce ____ and cause mass wasting to occur. The most damaging effect of storms is not necessarily the waves alone, but the waves in combination with storm surge (elevated sea level), created by the winds which pile water up along the shore. Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. Progressive waves move along the sea surface. Water depths are less than 1/20 the wave length. The forward movement of the wave form. In deep water most waves do not interact with the sea bottom and are called deep-water waves. Shore breakers (surf) are collapsing waves. In shallow water their length shortens and their height increases dramatically. Some of the greatest destruction comes from the storm surge or extreme high water levels due to the: Slower speeds than surface waves because the density difference between water masses is less than between air and water. (Figure 7-6b) Think of sloshing in bathtubs and or swinging in swing WebQuestion 13 of 254.0/ 4.0 Points What persistent behavior of waves produces longshore drift? There are two other notable types of progressive waves. B.. D. E. Which of these features signify a groundwater discharge area? - Wave form Seas, swell, and surf are progressive waves. Tsunamis which are seismic sea waves. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) Waves affect water to a depth equal to or less than one-half their wavelength. In shallow water, the sea bottom transforms the wave's properties. Progressive Waves Deep Water Waves (Figure 7-4a) Which of the following is NOT one of the three types of stream channels discussed in our text? Slower speeds than surface waves because the density difference between water masses is less than between air and water. Other Types of Progressive Waves Progressive waves move along the sea surface. There are two other notable types of progressive waves. Bottom friction alters both the http://dusk.geo.orst.edu/oceans/waves.html, - Drag along the bottom. When a stream enters a lake or ocean, the stream velocity slows. Internal Waves This interference may be: Transformation of Deep-water Waves: Dispersion (Figure 7-7a) - Constructive In the open ocean they have short heights, long wavelengths (>100 km), and long periods. Storm Surges Wave height/wave length. A special case is a tsunami, a deepwater wave generated by a submarine disturbance with incredibly long wavelengths, high wave speeds, and very short wave heights, UNTIL they feel the bottom in shallow water! Wind-generated waves are progressive waves because they travel across the sea surface. C. depends on the location Standing Waves The orbits of the water molecules are circular. The size of surface waves depends on the speed and duration of the wind, and the fetch. The result is amplification of the wave size which can lead to flooding. The crests build up and the troughs build down. Speed of the waves Fetch of the waves The number of waves in the wave train Angle that waves hit the shoreline Wavelength of the waves. They occur when water masses slip over one another. Dividing the wavelength by the wave period. There are two other notable types of progressive waves. Angle that waves hit the shoreline Which part of a coastal area is always under water? Seas, swell, and surf are progressive waves. Resonance Wave energy is focused where the lines converge. F. polarity Oscillate back and forth about a node i.e., a fixed point. A jetty may have bad consequences for beach nourishment. Which feature of a wave is most important to understand the energy of a wave? lectures | (Figure 7-6b) Waves originate in the fetch area. Storms affect shorelines in a variety of ways. Sudden shifting of the ocean floor due to earthquakes, volcanic eruptions, and submarine slumping. Rogue Waves? Slower speeds than surface waves because the density difference between water masses is less than between air and water. D. steeper gradients due to uplift In shallow water their length shortens and their height increases dramatically. - Drag along the bottom. In shallow water their length shortens and their height increases dramatically. A special case is a tsunami, a deepwater wave generated by a submarine disturbance with incredibly long wavelengths, high wave speeds, and very short wave heights, UNTIL they feel the bottom in shallow water! Wave Orthogonals (Figure 7-8) - Wave form The natural circular motion within the wave, Friction of the seafloor slowing waves, causing the crest to grow, How often does a full cycle of a tide occur? Constructive wave interference occurs when several wave crests or troughs coincide. Destructive Waves (Figure 7-6c) Geology Ch 12 Coastlines Flashcards | Quizlet There are two other notable types of progressive waves. A special case is a tsunami, a deepwater wave generated by a submarine disturbance with incredibly long wavelengths, high wave speeds, and very short wave heights, UNTIL they feel the bottom in shallow water! The orbits of the water molecules are circular. As waves enter shallow water their wavelength shortens and their height increases. Standing waves (seiches) do not move horizontally. - Fetch (distance over which wind blows) ______ streams only flow during rain events or the wet season. Wave Refraction (Figure 7-8a) Standing waves can be dangerous due to the phenomenon of resonance. 239 select all that apply. - Constructive The type of wave generated by wind is determined by: When the rate of discharge exceeds that of groundwater recharge, balances precipitation against evaporation and discharge. SELECT ALL THAT APPLY. A. Internal waves which occur underwater and move along pycnoclines. When this value is about 1/7, waves begin to break. The crests build up and the troughs build down. Because the moon orbits around the Earth in the same direction the Earth rotates, it takes more time for the same point on the Earth to be beneath the moon over the lunar day. moves heat around the planet, distributing it, Which of these features are found on emergent coastline, with a relative falling sea level? Think of sloshing in bathtubs and or swinging in swing Wave energy is focused where the lines converge. [ home port | cracks, possibly with some vertical displacement, occur upslope, What are some clues that a proposed home site may be susceptible to landslide activity? Period of wind or tides approximate the natural period of oscillation of the basin. labs | What is the process involved in the formation of the summer and winter berms? Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. - Drag along the bottom. email prof. ] Internal Waves Storms affect shorelines in a variety of ways. Internal waves which occur underwater and move along pycnoclines. Oscillate back and forth about a node i.e., a fixed point. - Drag along the bottom. It is wave energy not water molecules that moves across the sea surface. They occur when water masses slip over one another. Waves Break by Spilling Plunging, or Surging (Figure 7-9) Form when winds blow in one direction which causes water to pile up at one end of a basin. In the open ocean they have short heights, long wavelengths (>100 km), and long periods. Wave Refraction (Figure 7-8a) They are stationary and Shallow Water Waves (Figure 7-4b) -Friction with the bottom causes waves to slow down. http://dusk.geo.orst.edu/oceans/waves.html, It is the energy of the wave, not its mass that is in motion. select three. Why do some locations have especially high tidal ranges? Wave energy is focused where the lines converge. What important function do surface currents provide to the land? Standing waves (seiches) do not move horizontally. They occur when water masses slip over one another. Water depths are less than 1/20 the wave length. Progressive waves move along the sea surface. Breaking is determined by wave steepness The result is amplification of the wave size which can lead to flooding. Storm Surges - Low pressure which leads to a rise in sea level. - Constructive Think of sloshing in bathtubs and or swinging in swing -Tombolo Waves Entering Shallow Water
