How do you describe 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).
How many coastal areas are there?
Nine coastal states of India are– Gujarat, Maharashtra, Goa, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Odisha, West Bengal.
What are the examples of coastal features?
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. Some coasts are also changed by the flow of glaciers, which are huge rivers of ice, and lava from volcanoes.
What is a coastal area called?
The coast, also known as the coastline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the ocean or a lake.
What are the parts of sea coastline?

- Shoal.
Why are coastal areas important?
Importance of Coastal Waters Coastal waters support many fish species and provide breeding habitat for 85 percent of U.S. migratory birds. They also provide habitat for many other organisms such as marine mammals, corals, sea turtles, and submerged aquatic vegetation.
How is a coast formed?
Waves, tides, and currents help create coastlines. When waves crash onto shore, they wear away at, or erode, the land. But they also leave behind little parts of the sea, such as shells, sand dollars, seaweeds, and hermit crabs. Sometimes these objects end up as more permanent parts of the coastline.
What is coastal morphology?
Coastal morphology is the study of natural processes ongoing at the shoreline and of the impact due to human interventions within the coastal zone.
What is coastal topography?
Coastal Topography The shape of the coastline and its orientation to oncoming waves is also an important factor to consider. An area of coastline may be generally influenced by a large ocean fetch but because of its orientation it may be sheltered from destructive waves.
What are the characteristics of coastal landforms?
These regions are characterized by beaches, dunes, barriers, deltas, strandplains, backbarrier marshes, lagoons, and tidal flats. In extreme climates, such as along the Arctic coast, features are influenced by ice processes such as the patterned ground and ice-push barriers.
What are the types of coastal zones?
In general, coastal zones include the splash zone, the high intertidal zone, the low intertidal zone, and the low tide zone. Coastal zones are extremely sensitive to environmental perturbations.
What is the coastline?
The coast is the land along a sea. The boundary of a coast, where land meets water, is called the coastline. Waves, tides, and currents help create coastlines. When waves crash onto shore, they wear away at, or erode, the land.

What does a coast look like?
Where are coastal areas located?
In the United States, coastal plains can be found along the Atlantic Ocean and the Gulf of Mexico. Coastal plains can form in two basic ways. Some start as a continental shelf, a flat piece of land located below sea level. When the ocean level falls, the land is exposed, creating a coastal plain.
What is the coastal features diagram?
This diagram is a simpler version of the other coast features diagrams. It helps us understand that first caves are formed, followed by arches and then stacks. This coastal diagram is more detailed with ten features of coasts marked on. Coastal diagrams – wave action on coasts.
What is coastal geography?
NW Osmussaar, Estonia. Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography ( sociology and history) of the coast.
How do coastal processes shape the coast?
Below is a list of processes which help shape the coast. You can make a labelled diagram. Why not draw a labelled diagram explaining how these processes take place? small rocks are smashed against each other making smaller rocks. What coastal processes shape the coasts? higher sea levels lead to greater erosion shaping the coasts.
What are the main features of an exposed coastline?
Feature # 1. Capes and Bays: On exposed coasts, the continual action of waves on rocks of varying resistance causes the coastline to be eroded irregularly. This is particularly pronounced where hard rocks, e.g. granites and limestone’s, occur in alternate bands with softer rocks e.g. sand and clay.
