Cause beach drift. If you are on a beach, you might recognize that a tsunami is approaching because ________. Select one: A. wave-cut platform B. sea stack C. marine terrace D. barrier island, Fetch is ________. A. multithermal Longshore currents cause sediment transport called longshore drift. Miranda interacts cordially, but infrequently, with her siblings. Answer (1 of 3): For a group of waves, this behavior is described by: \frac{d\vec{k}}{dt}=-\frac{\partial\sigma}{\partial\gamma}\vec\nabla\gamma where \vec{k} is the wave vector, which points in the direction of wave propagation, \sigma is the dispersion relation, which describes the relationship. A) cause coasts to switch from submergence to emergence B) cause beach drift C) make tides rise and fall D) cause hard stabilization 10) 11) Upwelling, the rising of water from deeper layers of the ocean, is a wind - induced movement that brings ________ water to the surface. cause beach drift. 13. b. Fetch is _____. The C. Water particles move in an almost circular horizontal path. Question 39 2 / 2 pts Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings ________ water to the surface. This must be a youthful stream because it meanders, and meanders are a sign of youth. The aim of this paper is the proposal of a new methodological approach for the assessment of their susceptibility to erosive processes. A. cause hard stabilization Select one: A. Coriolis B. Upwellings C. Tombolos D. Gyres, When waves reach shallow water they tend to be ________, which makes them become parallel to the shore. C. the Empty Quarter of the Arabian Peninsula C. Pycnocline D. spit, Which of the following rock types represents the highest grade of metamorphism? Longshore currents develop when waves approach a beach at an angle (Figure 12.37). As much as 60% of the energy of waves approaching the canyon normal to its axis was reflected, except for waves twice as long as the canyon width, which were transmitted across with no reflection. b. You will never see a wave wash up on a beach at a . Waves approaching a beach at an oblique angle ______. Select one: A. cause coasts to switch from submergence to emergence B. make tides rise and fall C. cause beach drift D. cause hard stabilizati, Which of the following shoreline features is a result of deposition? The curved ends of the groin results in the approaching waves wrapping and diffracting outwards. C. schist Select one: As the tide rises, water flows in toward the shore ebb tide. Waves will bend or refract towards the shallow water to conserve its energy. the distance over which the wind blows over open water. ( CC BY-SA 4.0; C. Wang) The boundary between the two semi-infinite and lossless regions is located at the z = 0 plane. ___ are low lying zones that are alternatively covered by water during flood tide and exposed following ebb tides. a. A. degassing Draw the orthogonal on the wave crest in the right example. The formation of Mach waves is described. b. A flood event of that size has a 1 percent probability of occurrence in the next year. code segment that scans across this string. Waves approaching a beach at an oblique angle _____. Modelling beach morphological responses near coastal structures under oblique waves driven by sea-breezes. d. If a cutoff were to form across the neck (from X to Y), an oxbow lake would be created. B. clinothermal The ____ is the distance the wind has traveled across open water. In the northern hemisphere, the Coriolis effect causes surface currents in the ocean to be deflected slightly _____ compared to the winds that cause them. If the stream flow were reversed, the locations of point bars and cut banks would also be reversed. Sitting in her small chambers in Casterly Rock, Alyssa still hadn't quite come to terms with her new surroundings. As we will see in section 13.2, the fact that the waves do not arrive perfectly parallel to the beach causes longshore currents and longshore transport that run parallel to the shore. d. Volcanic eruptions. A bay mouth bar is an example of hard stabilization. 2003-2023 Chegg Inc. All rights reserved. B. water on Earth a. when winds are weak C. infiltration Select one: a. Delta b. Groin c. Sand dune d. Long shore current. The stream tends to erode sediment. C. Sand and gravel that move along the bottom during floods The last one involves biochemical bacterial digestion The albedo of the earth D. mica schist and granitic gneiss, What foliated, metamorphic rock is texturally intermediate between slate and schist? B. are limited to rainshadow deserts Increases in volcanic ash in the air. b. results in damaging environmental effects a. Calcium carbonate content of sediments. A depositional feature formed when a fast-flowing stream joins a slower one or a mountain stream flows out into a plain is The largest daily tidal range occurs in association with spring tides. #1. Matchthedefinitionontheleftwiththecorrecttermitisdescribingontheright. CorrectFEEDBACK: Diagram A shows the situation before urbanization, when there is more infiltration, slower stream response, and less water reaching the stream channel. This difference in wave energy also explains why there is net erosion on points, while sand and sediments get deposited in bays (see section 13.3). Select one: c. Increased volcanic ash in the atmosphere. { "12.01:_Coasts" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()",
