Quick Answer: What Are Coastal Features And Processes?

What are the coastal plains Class 9?

A coastal plain is a flat, low-lying piece of land next to the ocean.

To the east and west of the peninsular plateau, 2 narrow strips of plain lands are found, which are respectively called Eastern Coastal Plain and Western Coastal Plain..

What are the 4 types of coastal transportation?

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 the landforms in the coastal region?

Coastal Landform TypesDelta Landforms.Estuary Landforms.Lakeshore Landforms.Rocky Coast Landforms.Sandy Coast Landforms.Tropical Coast Landforms.

How can coastal processes be prevented?

Hard structural/engineering options use structures constructed on the beach (seawalls, groynes, breakwaters/artificial headlands) or further offshore (offshore breakwaters). These options influence coastal processes to stop or reduce the rate of coastal erosion.

What are the coastal processes?

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

What are the effects of coastal processes?

Already, coastal erosion costs roughly $500 million per year for coastal property loss, including damage to structures and loss of land. Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast.

What are the two main coastal processes that form coastal landforms?

Coastal landforms can be formed in two different ways, either by erosion (the wearing away of land by waves and wind) or by deposition (the building up of land through deposits of sand and other materials).

What are the main characteristics of coastal plain?

A coastal plain is a flat, low-lying piece of land next to the ocean. Coastal plains are separated from the rest of the interior by nearby landforms, such as mountains. In western South America, a large coastal plain lies between the Andes Mountains and the Pacific Ocean.

What is marine and coastal processes?

Coastal processes occur where waves break on a shore, not only on ocean/sea coasts but also on lakes/ponds. Waves Currents Still-water deposition Biological activity Tides Sea level rises. 4. Waves are usually caused by wind and controlled by wind speed.

What are the two main characteristics of coastal plains?

Geographically, coastal plains are regional features of low relief bounded seaward by the shore and landward by highlands (Freeman and Morris, 1958). Between the sea and the highlands they rise gently, frequently in a series of terraces or flats separated by scarps or hills to altitudes as high as 100–300 meters.

What is the importance of the coastal zone?

A coastal zone is the interface between the land and water. These zones are important because a majority of the world’s population inhabit such zones. Coastal zones are continually changing because of the dynamic interaction between the oceans and the land.

What are the uses of coastal plains?

Coastal plains are a source of salt, monazite (used for nuclear power) and mineral oil and gas as well as centres of fisheries. Although lacking in adequate natural harbours, with a number of major and minor ports, coastal plains are centres of commerce and have attracted dense human settlements.

What are the 4 types of coastal erosion?

ErosionHydraulic action – this is the sheer power of the waves as they smash against the cliff. … Abrasion – this is when pebbles grind along a rock platform, much like sandpaper. … Attrition – this is when rocks that the sea is carrying knock against each other. … Solution – this is when sea water dissolves certain types of rocks.

Where is the coastal zone found?

FACTORS DETERMINING COASTAL ZONE TYPES The common types of coastal zone are well represented along the shores of the United States. These types range from the ice-push coasts of Alaska to the coral reef coasts of Hawaii and southern Florida.

What are the 4 processes of coastal erosion?

These are corrasion, abrasion, hydraulic action, attrition and corrosion/solution.

What are coastal erosional features?

Erosional landforms include headlands, bays, caves, arches, stacks, stumps and wave-cut platforms. There are also depositional landforms such as beaches, spits and bars.

What are the common coastal hazard?

There are many different types of natural hazards, such as tornadoes, blizzards, drought, wildfire, volcanoes and earthquakes. … Coastal hazards refer to the risks of life and property on the coastline that are created by coastal flooding, high winds and waves, short- and long-term shoreline erosion, and storm surges.

What are coastal features?

A coast is a strip of land that meets an ocean or sea. … Coasts have many different features, such as caves and cliffs, beaches and mudflats. Tides, waves, and water currents (flow) shape the land to form these coastal features.

What is the meaning of coastal zone?

Definition of Coastal zone: (General, wide planning-oriented characterisation): The interface between land and sea, defined as the part of the land affected by its proximity to the sea (influence of marine processes), and the part of the sea affected by its proximity to the land (influence of terrestrial processes).

What do you mean by coastal areas?

Common term: Coastal area, Plural: Coastal areas. Short definition: Coastal areas are local administrative units (LAUs) that are bordering or close to a coastline. A coastline is defined as the line where land and water surfaces meet (border each other).

What are the different types of coastal landforms?
