The areas from which streams collect water are separated into ________, the borders of which are defined by local topographic highs. When this value is about 1/7, waves begin to break. Breaking is determined by wave steepness select two, Which type of mass wasting moves rapidly and can be deadly? Form when winds blow in one direction which causes water to pile up at one end of a basin. Waves originate in the fetch area. 239 Waves are disturbances that are generated on or beneath the sea surface. B. high porosity labs | - Wave form Seas, swell, and surf are progressive waves. Standing Waves In other words, as this increases, there is a deeper reach of wave base. Waves are disturbances that are generated on or beneath the sea surface. Internal Waves Why do some locations have especially high tidal ranges? 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! Standing Waves The size of surface waves depends on the speed and duration of the wind, and the fetch. Period of wind or tides approximate the natural period of oscillation of the basin. What happened in the 1925 Gros Ventre slide in Wyoming? Wave Orthogonals (Figure 7-8) All following actions can help mitigate the risk of mass wasting EXCEPT: building a house on top of a cliff to compress the material beneath it, When a landslide damn a river the resulting flooding can be deadly, Which of the following forces are NOT involved in a mass sliding down a slope, The shape of the water molecule is unique with two hydrogen ions bonded to the side of the oxygen ion. E. colorless They occur when water masses slip over one another. They occur when water masses slip over one another. The result is amplification of the wave size which can lead to flooding. This area is characterized by a "confused" sea state with extensive wave interference. Tsunamis - Persistent onshore winds. Period of wind or tides approximate the natural period of oscillation of the basin. http://dusk.geo.orst.edu/oceans/waves.html, - Wavelength shortens lectures | Waves Break by Spilling Plunging, or Surging (Figure 7-9) Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore currents velocity. Wave Motions Wind - Low pressure which leads to a rise in sea level. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) Slower speeds than surface waves because the density difference between water masses is less than between air and water. It is the energy of the wave, not its mass that is in motion. Storm Surges Storms affect shorelines in a variety of ways. depending on the slope of the bottom The size of surface waves depends on the speed and duration of the wind, and the fetch. - Differential speed along the crest. 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. They have very long periods and very large heights. Waves Entering Shallow Water Progressive waves move along the sea surface. WebMost common are surface waves, caused by wind blowing along the air-water interface, creating a disturbance that steadily builds as wind continues to blow and the wave crest C. contains drinkable water labs | lectures | Tsunamis Interaction with the sea bottom.

E. sea stack Waves are disturbances that are generated on or beneath the sea surface. Slower speeds than surface waves because the density difference between water masses is less than between air and water. - Constructive Breaking is determined by wave steepness As waves enter shallow water their wavelength shortens and their height increases. Water depths are less than 1/20 the wave length. Waves Break by Spilling Plunging, or Surging (Figure 7-9) Surfing Video: Condition Black Standing waves (seiches) do not move horizontally. When a stream reaches a low energy body of water, such as a lake or parts of the ocean , the velocity slows and the bed load and suspended load sediment come to rest, forming a _________. select three. - Low pressure which leads to a rise in sea level. lectures | Shore breakers (surf) are collapsing waves. Wind Generation of Waves They have very long periods and very large heights. - Speed decreases Waves affect water to a depth equal to or less than one-half their wavelength.

Why are ocean circulation patterns (shallow and deep currents) important for Earth? It is the energy of the wave, not its mass that is in motion. - Fetch (distance over which wind blows) Progressive waves move along the sea surface. - Persistent onshore winds. - Drag along the bottom. Storms affect shorelines in a variety of ways. Think of sloshing in bathtubs and or swinging in swing Shallow Waves Affected by Bottom E. offshore This leads to wave refraction and waves collapse forming surf (breakers).

Deep Water Waves (Figure 7-4a) Period of wind or tides approximate the natural period of oscillation of the basin. 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. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) ____________ causes surface currents, ___________ causes deep currents. Your return customer. Shallow-water Wave Transformations Standing waves can be dangerous due to the phenomenon of resonance. Standing Waves Some of the greatest destruction comes from the storm surge or extreme high water levels due to the: 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.
