An estuary formed from a flooded glacial valley is called a: An estuary produced by faulting or folding of rocks that creates a dropped-down section into which a river flows is called a: The large outflow of the Columbia River into the Pacific Ocean, causes: Which physical factor(s) influence(s) the surface circulation patterns in marginal seas? In addition to observing and obeying signs and flags that warn about rip currents, and swimming at beaches with lifeguards, learn what a rip current looks like so you can avoid them (Fig. e.wave refraction. Ooids, shallow water near shoe, warm water, gentle waves. Why do waves converge on headlands? - Answers oceanography ch. 8 quiz Flashcards | Quizlet Coastal processes of erosion include hydraulic action, attrition, corrosion and solution. A wave may break more than once, and in different ways, as it advances to shore. B) wave reflection. Where water is warm. 5.18. 5.10). 5.6. This means that the bathymetry (the underwater elevation) of the ocean or sea bed also impacts the strength of waves. If a coastline is all made of hard rock, then it will stay relatively firm and resistant to erosion and weathering, and therefore create a headland. b. they bounce wave energy back across the beach and cause erosion. The normal line is the horizontal dotted line. D. wind Deep ocean currents are driven primarily by ___ and caused by ___. c.The gravitational attraction just between the Earth and Sun. As waves approach a coastline they lose energy though because friction with the seabed increases. D)wave reflection. From organic remains of marine life, primarily plankton organisms and algae. Deep ocean circulation is driven primarily by __________. gravitational, Moon, Sun Larger waves tend to break in deeper water, farther from shore. In general, the speed, frequency, period, and energy of a wave are not affected by reflection. Waves converge on headlands due to: Wave refraction Which of the following from earliest to latest represents the typical order of formation of waves: Sea, swell, surf. 2003-2023 Chegg Inc. All rights reserved. -Pure destructive interference Which is technically the most correct with respect to tides? Why are headlands more susceptible to erosion than bays? The movement of sea water at a pynocline creates ____ waves. Why does wave height increase as waves enter shallow water? Wind blowing across the surface of the ocean. Density differences; differences in salinity and temperature. Save my name, email, and website in this browser for the next time I comment. The surf zone is the area near the coastline where waves break (Fig. 5.19). Surface ocean currents are driven primarily by ___ and modified by ____. Rogue waves are generated by destructive interference patterns of ocean swells. :) $12 tip if you get all the answers correct I need help with geography oceanography lab homework. -When waves with identical wavelengths interfere. What is the relationship between Atlantic inflow and evaporation rates in the Mediterranean Sea? The ratio of wave height to wavelength is called the: Waves that are moving faster than local wind and are sorted out by wavelength are called: The speed of a deep-water wave is proportional to: Tsunami travel as deep-water waves over the open ocean. When I do it myself I get all the answers correct but I don't haveenough time to, . A number of stages are involved: All rocks have lines of weakness; the sea and its waves use hydraulic action, abrasion and solution to erode along any lines of weakness. Study with Quizlet and memorize flashcards containing terms like Waves converge on headlands due to:, As a wave begins to feel bottom near a shoreline, its wave height:, The speed of a shallow- water wave is proportional to: and more. Earth is the only major body in the solar system on which there are active volcanoes. Are 0333 numbers included in free minutes? b. Waves are a type of erosion. An aerial view of the coastline in Kihei, Hawaii, shows reflection, refraction, and diffraction of water waves (Fig. The location of breaking waves at a particular location depends on the depth of the water and wave characteristics like wave height, wavelength, and direction of wave movement. Wave height increases. -the bending of waves due to a change in wavelength, -the bending of waves due to a change in wave velocity. As waves move into shallower water, they contact the bottom and begin to move slower (see theWave Energy and Wave Changes with Depth topic in the Waves unit). All Rights Reserved. Why do ocean waves bend around headlands? waves converge on the headlands due to wave refraction, they bounce wave energy back across the beach and cause erosion, When waves approach the shore and enter shallow water, the waves slow down and the wave height increases, seacliffs are exposed to wave action, and they are also steep slopes, which can make them susceptible to landslides. Based on the graph, which of the following has the highest density? In general, bays will have more sedimentation, because they have less wave energy, and headlands will have more erosion, due to the higher amount of wave energy reaching them.
