The combination of wave refraction, longshore current and beach drift result in a number of different shoreline erosional and depositional features. Your email address will not be published. Match the correct letter to each of the following features. Erosion is defined as wearing away of rock along the coastline. When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands. When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands. The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island. Label a baymouth bar and a spit in Figure 12.8L Figure 12.8 Image to accompany Question 4. 5. Deposition is the wearing away of the land by the sea. . A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. A double tombolo encloses a lagoon that eventually fills with sediment; fine examples of these occur off the coast of Italy. C: Arrow that points in the OPPOSITE direction of longshore drift A pebble or sand particle moves from point A to B, carried by the swash up the beach , the angle determined by the wave and wind direction. What are Tombolos and how are they formed? Tombolo, 2. Intranet Ciusss Est, A tombolo, from the Italian tombolo, meaning pillow or cushion, and sometimes translated as ayre, is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar. It is a depositional landform and it is formed the same as sandspits. Cuspate forelands, also known as cuspate barriers or nesses in Britain, are geographical features found on coastlines and lakeshores that are created primarily by longshore drift. Where can you find a double tombolo in Italy? There are four types of erosion by waves: Abrasion - waves carry material which thrashes against the cliff and progressively disintegrate it. 2. A tied island refers to an island which is connected to the mainland by a narrow piece of land called a tombolo. How is a beach formed by deposition Sometimes due to deposition of waves and currents, both ends of the bar join to enclose a part of sea water between the coast and the bar. These are the most obvious defensive methods. D: Barrier flat (third from right). A tombolo is a sandy isthmus. A sea arch is a natural opening eroded out of a cliff face by marine processes. Results for free physical weathering and erosion activities The construction projects on artificial Riyue islands have led to a fast change of coastal erosion and deposition on Riyue bay.The erosion of the southwest coast has threatened the development of the vitica mangachapoi forest natural reserves on the land.Monitoring and management of Riyue bay becomes an urgent demand.With the studies of multi . True When the waves broke, their energy was used to deposit sand into a bar along the sea floor.

Once attached, the island is then known as a tied island. They can also trap sediment by ponding and settling out sheet flow runoff, or by filtering sediment as runoff passes through permeable berms. Spits often have salt marshes build up behind them because the spit offers protection from the stronger waves and the wind, allowing salt tolerant plants to grow. Played 0 times. Many beaches have been eroded and the obvious environmental and landscape degradation of many coastal stretches are problems that coastal engineers are spending time solving. Coastal landforms can be either depositional or erosional. B: Spit Spits and Tombolo: A sand spit is an extended stretch of beach material (linear accumulation of sediment) that projects out to sea and is joined to the mainland at one end. The island is then referred to as a linked island once it has been joined.Due to sand accretion in the lee of the island, where wave energy and longshore drift are reduced and hence sand deposition occurs, the shoreline creeps toward the island (or detached breakwater). On deposition The study area is part of the [6], Deposition landform in which an island is connected to the mainland by a sandy isthmus, Glossary of Geology and Related Sciences.

Soft engineering defines natural defences, typically considered inexpensive, long term and sustainable, whereas hard engineering represents artificial structures which are arguably short term, expensive and unsustainable solutions to coastal erosion. In some area, bars extend to join the mainland to an island. Formed by accretion and progradation of sand and shingle, they extend outwards from the shoreline in a triangular shape. Many natural pocket beaches exist throughout the world. The image below depicts shoreline features characteristic of erosional coasts. This island-like landform is actually attached to the coast by a thin sand bar or spit. 7. Hence, the correct answer is option (2). C. B. Some landforms created by erosion are platforms, arches, and sea stacks. Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Erosional coasts are characterized by features of accumulated sand/pebble/rock that are eroded elsewhere and deposited on shore where longshore currents slow. Shore Platform. They often are complexly curved, with a characteristic recurved head (hook); this probably results from the refraction of waves around the spit's end.
