Why are cliffs common along the coast?

Cliffs are usually formed because of processes called erosion and weathering. Weathering happens when natural events, like wind or rain, break up pieces of rock. In coastal areas, strong winds and powerful waves break off soft or grainy rocks from hardier rocks. The harder rocks are left as cliffs.

What are the 4 types of coastal transportation?

These are:

  • Solution – when minerals in rocks like chalk and limestone are dissolved in sea water and then carried in solution.
  • Suspension – small particles such as silts and clays are suspended in the flow of the water.
  • Saltation – where small pieces of shingle or large sand grains are bounced along the sea bed.

What is a sheltered coast?

Sheltered coasts (defined in Chapter 1) are found in estuaries, lagoons, or sounds where the shore exposure is fetch limited. Rising sea levels inundate old fluvial systems and create geomorphic units that are generally shorter (measured parallel to the shoreline) than units on open-ocean coasts.

How many types of coastal transportation are there?

Traction – large pebbles and boulders are rolled along the seafloor. Saltation – beach material is bounced along the seafloor. Suspension – beach material is suspended and carried by the waves. Solution – material is dissolved and carried by the water.

What are natural coastal processes?

The results of actions and interactions of these natural forces on the shoreline and near-shore seabed are called coastal processes. These include erosion and deposition, movement of dunes, longshore drift, and the effects of storms on the coastline.

What are the examples of the coastal processes?

Coastal Processes

  • Waves.
  • Tides.
  • Near-Shore Currents.
  • Shoreline Weathering.
  • Coastal Erosion.
  • Sediment Transport and Deposition.
  • Organic Activity.
  • Changes in Sea Level.

Why do coastal areas need to be protected?

Some areas are in greater need of protection than others. For example there are a variety of reasons specifically economic and social (socio-economic) why seaside towns need to be protected. They are places where people live and they are also places where money can be made specifically through tourism.
