When looking at the distribution of precipitation in the United States, the ________ meridian approximately divides the wet eastern from the dry western states. labs | Why do some locations have especially high tidal ranges? Resonance Waves which interact with the sea floor are known as shallow-water 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! Standing waves can be dangerous due to the phenomenon of resonance. Moving sand _____ causes surface currents, _____ causes Internal Waves C. contains drinkable water Formula on pg. Formula on pg. 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! (Figure 7-6b) F. car exhaust in the winter [ home port | In shallow water their length shortens and their height increases dramatically. Period of wind or tides approximate the natural period of oscillation of the basin. Standing waves (seiches) do not move horizontally. [ home port | Transformation of Deep-water Waves: Dispersion (Figure 7-7a) Form when winds blow in one direction which causes water to pile up at one end of a basin. They occur when water masses slip over one another. - Height increases This interference may be: Storms affect shorelines in a variety of ways. 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. Deep Water Waves (Figure 7-4a) - Constructive In other words, as this increases, there is a deeper reach of wave base. Introductory Geology Water 5.11 Student Responses 1. a. What forces are involved in a mass sliding down an inclined plane? Waves are disturbances that are generated on or beneath the sea surface. It is the energy of the wave, not its mass that is in motion. A. exactly 12 hours - Speed decreases - Fetch (distance over which wind blows) All of the following are ways in which sedimentary rocks form EXCEPT: A mixture of Fe2O3Fe_2O_3Fe2O3 and FeOFeOFeO was found to contain 72.00% FeFeFe by mass. Resonance C. Madison Canyon Internal waves which occur underwater and move along pycnoclines. Tsunamis which are seismic sea waves. Think of sloshing in bathtubs and or swinging in swing This area is characterized by a "confused" sea state with extensive wave interference. In shallow water their length shortens and their height increases dramatically. Life History of Ocean Waves (Cont.) Answers: A. -Depends on the location In the open ocean they have short heights, long wavelengths (>100 km), and long periods. - Wind velocity Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) - Persistent onshore winds. 239 Wave energy is defocused where the lines diverge. Internal waves which occur underwater and move along pycnoclines.
