Question 5 of 24 worth 1 point generalizing patterns

This preview shows page 2 - 5 out of 8 pages.

Question 5 of 24 (worth 1 point) Generalizing, patterns of orthogonals indicate that wave crests approaching a shoreline at oblique angles are refracted or bent, ______. A. toward the shoreline B. away from the shoreline Answer Key: A
Question 6 of 24 (worth 1 point) Figure 2 depicts water waves approaching an embayed coastline. The pattern of wave crests illustrates the effects of an irregular coast on approaching waves. Arrows depicting segments of orthorgonals are drawn along the deep-water wave crest. Complete the drawing of the orthogonals to shore. Your analysis shows that orthogonals of wave crests approaching a headland refract ______ the headland, thereby concentrating wave energy.
Question 7 of 24 (worth 1 point) The pattern of orthogonals you drew centered on the bay area indicates that the orthogonals refract _____ the midpoint of the bay shore thereby spreading out wave energy.
Question 8 of 24 (worth 1 point) Generalizing, _____ orthogonals indicate the concentration of wave energy.
Question 9 of 24 (worth 1 point) On the other hand, orthogonals denote the dispersal or spreading out of wave energy when _____. Where wave energy is concentrated, erosion can be expected (e.g., undercutting of seaside cliffs).. Where wave energy is dissipated, its carrying capacity for sediment is reduced and particles settle out of suspension. A. converging B. diverging
Answer Key: B
Question 10 of 24 (worth 1 point) Consequently, headlands are places of _____.
Question 11 of 24 (worth 1 point) Bays are places of sediment _____.
Question 12 of 24 (worth 1 point) Based on differences in width of the barrier island beach on either side of the tidal inlets and knowing that beach sediments accumulate on the sides of jetties facing the oncoming longshore current and erode on the down-current sides, the prevailing direction of littoral drift is from _____.
