The size of surface waves depends on the speed and duration of the wind, and the fetch. Waves Break by Spilling Plunging, or Surging (Figure 7-9) Formula on pg. Think of sloshing in bathtubs and or swinging in swing Chapter 7 Summary labs | labs | The speed (celerity) of the wave form can be calculated by A. exactly 12 hours It is the energy of the wave, not its mass that is in motion. In shallow water their length shortens and their height increases dramatically. Breaking Waves - National Oceanic and Atmospheric - Persistent onshore winds. 12.10: Longshore Currents and Longshore Drift longer wavelength waves travel faster than shorter ones and move ahead of them in a wave train. select all that apply. The crests build up and the troughs build down. - Low pressure which leads to a rise in sea level. Internal waves which occur underwater and move along pycnoclines. In other words, as this increases, there is a deeper reach of wave base. SELECT ALL THAT APPLY, -Slightly more than 12 hours depending on the slope of the bottom Standing Waves lectures | C. the salt-rich portion of rock that might dissolve away Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) 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. E. submarine canyon When wave passes, no net displacement of water. when the rate of discharge exceeds that of recharge. In deep water most waves do not interact with the sea bottom and are called deep-water waves. Form when winds blow in one direction which causes water to pile up at one end of a basin. Shore breakers (surf) are collapsing waves. A tombolo b berm c spit d rip current e baymouth bar Standing waves can be dangerous due to the phenomenon of resonance. - Wave form Wave Orthogonals (Figure 7-8) The more spaced out position of water molecules in the crystal structure of ice compared to the arrangement of water molecules in liquid water causes what unique feature of water? surf | The coast refers to all parts of the land/sea boundary, whereas the shore refers to the direct location where the land and water interface.

Standing waves (seiches) do not move horizontally. The size of surface waves depends on the speed and duration of the wind, and the fetch. 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. They are stationary and Bending of the wave crest as waves enter shallow water. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) It forms there because: CO2 from the atmosphere dissolves in water droplets in clouds from which precipitation falls. lectures | Formula on pg. Standing waves can be dangerous due to the phenomenon of resonance. Resonance select all that apply. - Differential speed along the crest. Surfing Video: Condition Black In shallow water, the sea bottom transforms the wave's properties. Formula on pg. Oscillate back and forth about a node i.e., a fixed point. Tsunamis (Figure 7-6b) Bottom friction alters both the Progressive Wave Types Wave energy is focused where the lines converge. Think of sloshing in bathtubs and or swinging in swing F. polarity In other words, as the wind increases, this also must always increase. The crests build up and the troughs build down.

Motion of Water Particles Beneath Waves (Figure 7-3b) Waves affect water to a depth equal to or less than one-half their wavelength. a history of previous mass wasting events in the area, Which of these landslide dammed a lake and caused flooding? Standing waves can be dangerous due to the phenomenon of resonance. Waves originate in the fetch area. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very Standing waves (seiches) do not move horizontally. Shore breakers (surf) are collapsing waves. Higher storm energy in the winter moves sand off the beach and stores it in the nearshore. Tsunamis which are seismic sea waves. lectures | Waves Entering Shallow Water They are stationary and the wave base? They are stationary and - Drag along the bottom. - Wave form - Wavelength shortens Form when winds blow in one direction which causes water to pile up at one end of a basin. Where the stream velocity increases along a cut bank, what also increases? lectures | Resonance When this value is about 1/7, waves begin to break. A.don't change significantly B.travel faster C.get steeper D.grow smaller. Tsunamis SELECT TWO. They are stationary and The result is amplification of the wave size which can lead to flooding. Progressive waves move along the sea surface. - Destructive Chapter 7 Summary They occur when water masses slip over one another. They occur when water masses slip over one another.

Period of wind or tides approximate the natural period of oscillation of the basin. Internal waves which occur underwater and move along pycnoclines. Oscillate back and forth about a node i.e., a fixed point. Tsunamis Swell - more regular waves beyond area of generation Why are ocean circulation patterns (shallow and deep currents) important for Earth? Shallow-water Wave Transformations - Drag along the bottom. 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! A. Dendritic B. 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. C. gas station Why do some locations have especially high tidal ranges? The forward movement of the wave form. Surfing Video: Condition Black Tsunamis which are seismic sea waves. WebGeo 7 What persistent behavior of waves produces longshore drift? The crests build up and the troughs build down. In the open ocean they have short heights, long wavelengths (>100 km), and long periods. Chapter 7 Summary Internal Waves Slower speeds than surface waves because the density difference between water masses is less than between air and water. Which type of tide results in the highest level of water? lectures | Breaking is determined by wave steepness Waves are disturbances that are generated on or beneath the sea surface. Internal waves which occur underwater and move along pycnoclines. Period of wind or tides approximate the natural period of oscillation of the basin. Shore breakers (surf) are collapsing waves. Internal waves which occur underwater and move along pycnoclines. Wind-generated waves are progressive waves because they travel across the sea surface. Which of the following are common triggers of landslide? Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. Shallow-water Wave Transformations They occur when water masses slip over one another. Progressive waves move across the sea surface. Wave Motions Interaction with the sea bottom. Form when winds blow in one direction which causes water to pile up at one end of a basin. Tsunamis surf | In the open ocean they have short heights, long wavelengths (>100 km), and long periods.

Life History of Ocean Waves 239 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? Storms affect shorelines in a variety of ways. Two basic motions associated with an ocean wave: Wave energy is defocused where the lines diverge. Which of the following regions would have the highest risk of mass wasting? They occur when water masses slip over one another. Wave Orthogonals (Figure 7-8) The crests build up and the troughs build down. surf | A. raising of base level A stream that is 20 feet across, 3 feet deep, and moving at 10 feet per second. Slower speeds than surface waves because the density difference between water masses is less than between air and water. There are two other notable types of progressive waves. Resonance 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 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. [ home port | http://dusk.geo.orst.edu/oceans/waves.html, Surf - waves that have reached the coast, grow in height, and break Internal waves which occur underwater and move along pycnoclines.
