What type of stream drainage pattern is present on this map? Waves are disturbances that are generated on or beneath the sea surface. When this value is about 1/7, waves begin to break. - Wind velocity Dividing the wavelength by the wave period. Which mass wasting type is very slow movement that can cause fences, retaining walls, and telephone poles to tilt downhill? Waves Break by Spilling Plunging, or Surging (Figure 7-9) Standing Waves - Wavelength shortens - Persistent onshore winds. Question 13 of 25 40 40 points what persistent - Course There are two other notable types of progressive waves. B.. D. E. Which of these features signify a groundwater discharge area? - Height increases 239 Why build them in the first place? email prof. ] The forward movement of the wave form. The type of wave generated by wind is determined by: Longshore Currents - NOAA's National Ocean Service D. normal Surfing Video: Condition Black Answers: A. C. What happens to the wave train because of wave dispersion? - Celerity http://dusk.geo.orst.edu/oceans/waves.html, Oscillate back and forth about a node i.e., a fixed point. Rogue Waves? lectures | Other Types of Progressive Waves Progressive Wave Types When the rate of discharge exceeds that of groundwater recharge, balances precipitation against evaporation and discharge. Slower speeds than surface waves because the density difference between water masses is less than between air and water. select all that apply. - Low pressure which leads to a rise in sea level. Shallow Waves Affected by Bottom Slower speeds than surface waves because the density difference between water masses is less than between air and water. Period of wind or tides approximate the natural period of oscillation of the basin. Storms affect shorelines in a variety of ways. Breaking is determined by wave steepness - Fetch (distance over which wind blows) email prof. ] Storm Surges email prof. ] Some of the greatest destruction comes from the storm surge or extreme high water levels due to the: They are stationary and Wave energy is focused where the lines converge. 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. email prof. ] In the open ocean they have short heights, long wavelengths (>100 km), and long periods. Wave energy is defocused where the lines diverge. An ocean wave is an undulation of the sea surface. The crests build up and the troughs build down. Wind-generated waves are progressive waves because they travel across the sea surface. Surf - waves that have reached the coast, grow in height, and break Standing waves can be dangerous due to the phenomenon of resonance. It is due to: Progressive waves move along the sea surface. There are two other notable types of progressive waves. In shallow water their length shortens and their height increases dramatically. Bending of the wave crest as waves enter shallow water. Oscillate back and forth about a node i.e., a fixed point. 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. Tsunamis Some of the greatest destruction comes from the storm surge or extreme high water levels due to the: Transformation of Deep-water Waves: Dispersion (Figure 7-7a) Waves affect water to a depth equal to or less than one-half their wavelength. There are two other notable types of progressive waves. Waves affect water to a depth equal to or less than one-half their wavelength. The result is amplification of the wave size which can lead to flooding. Rogue Waves? Waves originate in the fetch area. They have very long periods and very large heights. Waves originate in the fetch area. lectures | When this value is about 1/7, waves begin to break. In deep water most waves do not interact with the sea bottom and are called deep-water waves. In the open ocean they have short heights, long wavelengths (>100 km), and long periods. Answers: A. C. D. Which of these contaminants plays the biggest role in the growth of blue-green algae? Wave Refraction (Figure 7-8a) Wave energy is defocused where the lines diverge. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) In shallow water their length shortens and their height increases dramatically. Form when winds blow in one direction which causes water to pile up at one end of a basin. 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! Other Types of Progressive Waves The orbits of the water molecules are circular. Storm Surges Tsunamis which are seismic sea waves. Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. A. fields of an agricultural area - Wind duration - Differential speed along the crest. It is wave energy not water molecules that moves across the sea surface. Resonance - Persistent onshore winds. Standing Waves They occur when water masses slip over one another. email prof. ] The forward movement of the wave form. Webaway Question 18 What persistent behaviorofwaves produces longshore drift? Waves originate in the fetch area. Deep Water Waves (Figure 7-4a) Waves Break by Spilling Plunging, or Surging (Figure 7-9) C. sea arch Wave energy is focused where the lines converge. Answers: A. D. E. F. Carbonic acid is present in all precipitation. Wind B. flowing well The result is amplification of the wave size which can lead to flooding. http://dusk.geo.orst.edu/oceans/waves.html, Tsunamis which are seismic sea waves. The size of surface waves depends on the speed and duration of the wind, and the fetch. They are stationary and Dividing the wavelength by the wave period. - Celerity Which feature of a wave is most important in order to understand the wave base of a wave's motion?
