Tidal phases are determined by bathymetry: the _________ of ocean basins and the continental _________ that are used in the way of the tidal envelope within which the Earth rotates. Form when winds blow in one direction which causes water to pile up at one end of a basin. 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 Progressive waves move along the sea surface. Surfing Video: Condition Black In shallow water, the sea bottom transforms the wave's properties. Standing waves (seiches) do not move horizontally. labs | A. marine terrace The speed (celerity) of the wave form can be calculated by They occur when water masses slip over one another. A. gaining stream http://dusk.geo.orst.edu/oceans/waves.html, They occur when water masses slip over one another. As waves enter shallow water their wavelength shortens and their height increases. - Persistent onshore winds. Answers: A. Sudden shifting of the ocean floor due to earthquakes, volcanic eruptions, and submarine slumping. surf | Standing waves (seiches) do not move horizontally. - Fetch (distance over which wind blows) Waves Break by Spilling Plunging, or Surging (Figure 7-9) The number of waves in the wave train B. The difference between high and low tide is called what ? labs | Higher storm energy in the winter moves sand off the beach and stores it in the nearshore. All of the following factors affect the probability of mass wasting EXCEPT: Which of the following mass wasting mitigation efforts is characterized by spraying reinforced concrete onto a slop surface? Why is the Colorado River Compact (as conceived and amended) likely to cause problems in the future? Form when winds blow in one direction which causes water to pile up at one end of a basin. http://dusk.geo.orst.edu/oceans/waves.html, In shallow water their length shortens and their height increases dramatically. Internal Waves - Wave form Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. It is due to: D. gravity on land decreases because of felsic composition E. Rock towers Bending of the wave crest as waves enter shallow water. When this value is about 1/7, waves begin to break. 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 duration Period of wind or tides approximate the natural period of oscillation of the basin.
