Question

The boundary between the water and the land shoreline beach face coastline shore The area between the lowest low tide and the area affected by storm waves nearshore beach face berm shore A steep slope of sediment that extends to the shoreline and is washed by the waves. foreshore offshore near shore Beach Why is Sandy Beach. Puerto Penasco. Mexico considered a high energy beach? All of the above. It has strong breaking waves. There is an abundance of sand along the beach. The foreshore is very short. How was the coquina at Sandy Beach (Mexico) created? The weight of the overlying sediments compressed the shells and they fused as a result of the pressure. The coquina was created by low level metamorphism during the last Ice Age. It was created through the action of groundwater depositing cement between the grains. The shell fragments were cemented together by intertidal algae and corals. The area called Cholla Bay near Puerto Penasco is only about one mile away from Sandy Beach, but Cholla Bay is a low energy environment. How can two areas, so close together, be so different? The water in Cholla Bay is so deep that strong currents can not develop. There are numerous reefs of coral in Cholla Bay. These reefs break the waves so that little wave action strikes the beach. Cholla Bay is protected from the strong waves coming from the south. The strong longshore current that is formed at Sandy Beach transports sediments to Cholla Bay. The accumulation of sand in the area of Cholla Bay slows the current and results in lower energy. Waves can cause a large amount of erosion as well as abrasion, especially when the water is loaded with sand and other sediments. However, even water without sediment can cause erosion through a process called cavitation sublimation swash backwash

Explanation / Answer

SOLUTION NO-16.

'A' Shoreline is the correct option.

A shoreline is the boundary in between just before reaching the surface of wave and wave flowing towards surface.
