Composed of chemical properties such as calcium carbonate (CaCO3). e.The gravitational attraction among the oceans, mountains, and the moon. Fig. (B) A sign at Haena Beach Park, Kauai, HawaiI, warns swimmers that rip currents can sweep swimmers out to sea. a.at a density boundary within the ocean. In terms of erosion protection from wave action, seawalls: Relative (local) changes in sea level might include: a.tectonic activity resulting in a regional coastline that is higher or lower. Wave refraction and diffraction cause converging wave fronts on headlands and diverging wave fronts in bays. Wavelength decreases. Manganese nodules In general, if the bottom is very sloped, the resulting wave will be spilling. Fig. Will Xbox Series X ever be in stock again? As a wave moves into increasingly shallow water, it continues to grow in height. A wave cut platform refers to the narrow flat area often seen at the base of a sea cliff caused by the action of the waves. Coastal features are constantly changing; the same beach can look different over the span of a season or even a day. siliceous ooze (SiO2, plankton shells). 5.2). -When two waves that are 180 degrees out-of-phase interfere. A rip current is strongest at its neck, where the currents merge and flow back to sea through a deeper channel (Fig. Discordant coastline occurs where bands of differing rock type run perpendicular to the coast. Which of the following statements about storm surge is CORRECT? e. wave refraction. Fig. These lines of weakness get enlarged and develop into small sea caves. Image courtesy of Cecilia and Randy Lascody, from National Oceanic and Atmospheric Administration (NOAA). Coastal Processes Flashcards | Chegg.com 5.22). Waves converge on headlands due to _____. -Wave refraction at the headland decreases deposition at the headland and causes erosion in adjacent bays. Test Prep. How did the original headland become eroded to the present coastal landscape? The uplift of downdropping of large areas of the sea floor creates ____ waves. -the furthest distance a wave can get to shore before dissipating -The wavelength of the wave must be contained within a smaller water column in shallow water. How does wave amplitude change with depth in water? The speed of a deep-water wave is proportional to ________. a series of water waves that travel away from a fault in all directions at a high speed. In general, a good surf spot is one that breaks fairly often and in a manner that offers rideable waves. 5.20. Suggest a correction? You can use the same procedure to make a profile of the area outside your classroom. -Wave amplitude decreases as depth increases. Surface ocean currents are driven primarily by ___ and modified by ____. It issues tsunami warnings to 25 Pacific rim nations when data suggest a tsunami is imminent. Surging breakers (Fig. :) $12 tip if you get all the answers correct I need help with geography oceanography lab homework. Any shoreline construction causes change in the beach environment. b.rise in sea level due to a large weight of glacier on a continental mass. -the distance between consecutive wave crests or troughs -the closest distance a wave can get to shore before breaking, the lower limit of wave-induced motion in the water. Which ocean is associated with most tsunamis? 5.21. What are the main causes of tides on Earth? d. are important feeding/resting points for migrating birds. 5.6. -Pure destructive interference c. Earth rotates into and out of tidal bulges. Coastal upwelling along the coast of Chile is a result of winds from the ___ turning towards the ____ due to Ekman transport. where storm waves move against strong surface currents. -Freak waves -the time it takes for one wavelength of a wave to pass a particular point 5.19. C) spilling breakers. Energy travels as right angles to the direction of the vibrating particles in ____. If the map does not display but requires you to log in your organization account, log out of your organization account in the browser, and then refresh this page. A rip current can also form when water from an incoming high tide or from large waves flows over a bar or reef; the water then flows in a rip current back to sea through a gap or deep area in the bar or reef. A wave train is caused by wave energy moving more slowly than individual waves. Use a ripple tank to observe various properties of propagating waves including interference, reflection, refraction, and diffraction. Most ocean waves form as a result of ____. Is Harlech Castle part of National Trust? These differences in energy can affect the shape of the coastline. Wave refraction at the headland increases erosion at the headland and causes deposition in adjacent bays. Eddies can transport nutrients onshore, offshore, or from deep water, helping to maintain populations of plankton. Where few streams bringing in lithogenous sediment. Multiple Choice Waves converge on headlands due to: A)constructive interference. The time it takes for a full wave to pass a stationary object is called the wave: Period. Uploaded By wildrider9896; Pages 182 Ratings 71% (35) 25 out of 35 people found this document helpful; This document may be freely reproduced and distributed for non-profit educational purposes. The tsunami warning system uses seismic waves and deep-ocean pressure sensors to detect tsunami. Waves are a type of erosion. Focusing Beyond the Diffraction Limit with Far-Field Time - Science -When waves with identical wavelengths interfere. Constructive wave, A problem with the worldwide shark fisheries is __________. Equatorial currents are driven by the ____. Four common types of surfing breaks include beach, point, reef, and river mouth: Tides can dramatically affect the quality of surf because they influence both water motion and the relative depth of the bottom contour. Standing waves may be caused by _____. Larger waves tend to break in deeper water, farther from shore. The El Nio Southern Oscillation can best be described as ____. -the lowest part of the wave How do headlands and bays form on discordant coastlines? Fossilized remains of ancient marine life. between two successive waves is called the _________. -Havoc waves How are positive and negative charges distributed on a water molecule? -The energy of the wave must be contained within a larger water column in shallow water. This is because offshore winds help to hold the face of the wave up and open, to provide a smooth, surfable surface. Buried sediment on the continental shelf. d. Earth only has only one tidal bulge facing either the Sun or the Moon. Oceanography Exam 2 Dubbs Flashcards | Quizlet
