Question

the work of sea waves is confined to a narrow belt along the coast.explain the erosional and the depositional features created by the sea waves

Answer 1

Answer:

The following points may help you:

a. Coastal landforms are the result of sea waves. They may create and change the existing landforms.

b. The dispositional and erosion feature of sea waves forms beaches

c. Besides that other structures formed through sea wave erosion are sea cliffs, which is the result of the impacting lower part of the rocks,whereby the upper part projects towards the sea leaving the vertical wall behind.

d. Sea caves is also an important feature, which is the result of continuos striking of waves on the rocks. They also result in the formation of sea arches.

e. Later when the roof of the arch is broken , it also takes a form of sea stacks.

Explanation:

Erosional and Depositional Coasts

PrintPrint

Another approach to coastal classification is to consider whether coastal processes in the coastal zone are primarily contributing sediment to the coastline or whether they are removing sediment from the coastline. The former of these is recognized as deposition, whereas the latter is known as erosion. Where erosion is the dominant process, the coastline is retreating landward, and where deposition is the dominant, the coastline is advancing seaward.

Erosional Coasts

In places where there is an abundance of wave energy or ocean currents and/or a lack of sediment available for deposition, erosion of the coast will be the dominant mechanism of change. Quite often, erosional coasts are narrow and characterized by resilient rocky shorelines that are exposed to high energy waves and supply relatively little sediment to the adjacent shore. This is the case for much of the western U.S. where there are numerous rocky exposures and vertical sea cliffs. Often, but not necessarily always, erosional coasts are associated with coastal zones along active plate margins where there is a steady uplift of the landform, and few well-developed drainage basins and rivers systems have developed to deliver large quantities of sediment to the coast.

Depositional Coasts

Depositional coasts are characterized by abundant sediment supply that results in the net deposition of sediment and creation of new coastal landforms despite the energy of the waves and ocean currents. There is a wide variety of landforms along depositional coasts such as extensive beaches, barrier islands, and expansive coastal wetlands and mudflats. They are most common along mature, tectonically inactive continental margins where ample geologic time has passed for large drainage basins and rivers to develop, which can provide large quantities of sediment that can be distributed by waves and tides at the coastline
