What Depositional Landforms are created on Coast

Who would not like to enjoy a shower, sunbath, playing with sand, water games and activities, sitting idle and looking towards the ocean, sea, and river on the beach.
But do you ever tried to get to know about that, how these beaches are formed? From where this much sand, sediments, rocks, pebbles came on the beach? 

Here are the answers to these questions. What all you need to do is to continue reading with me. In this post you came to know how all depositional landforms are formed on the coast or shoreline.

Depositional Landforms on Coast

When the sea and ocean waves deposit all its eroded material like sand, sediments, silt, shells, pebbles, rocks on the shore leads to form various beautiful mesmerizing landforms called depositional landforms.

Five depositional landforms are:

1. Beaches

  • These are very beautiful depositional features alongside the water bodies like the ocean, sea, river, pond, and lake.
  • It is a narrow strip of land which separate the mainland and water body like ocean, sea, river, pond, and lake.
  • It is made up of sand, sediment, rocks, seashells, silt, pebbles, stone.
  • The slope of the beach is very gentle.

For example, Miami Beach, Grand Anse Beach of Seychelles, Cabbage Beach of Bahamas, Sunshine Beach of Thailand.

2. Coastal Dune

It is loose sand small hill shaped depositional landform along the coastline. Formed when winds and waves transport and deposit sand on to the beach.
These dunes protect the coastline land areas against strong waves of seas and oceans. That time these dunes act as a barrier.

For example, Silver Lake Sand Dunes, and Grand Sable Banks and Dunes.

3. Lagoons

It is comparatively a shallow body of water than the main water body i.e ocean, seas, and river, attached to the mainland.
Formed due to separation of some part of the main water body by a narrow landmass generally known as sand bars, barrier island, or coral reefs.
It looks like a shoreside shallow lake having arc-shaped features.

There are two types of Lagoon are: 

  • Atoll
  • Coastal

For example, Garabogaz- Gol lagoon in Turkmenistan, The Blue lagoon and Cominotto island, Chilika lake of Odisha, India, Pulicat Lake of India.

4. Sand Spits

It is an extended stretch of beach material into the sea or ocean from the front side and its back end attached to the mainland.
Formed when waves meet the beach at the oblique angle, moving sediments or sand down the beach into open waters and deposit here in a narrow strip.

For example, Hel spit of Poland, Feelotova spit of Ukrain, Farewell spit of New Zealand, Spurn point.

5. Bars

It is a thin ridge made up of sand and gravel (mostly) joins the two headlands. It Acts like a bar or barrier between the bay and land area, that is why it is called as bars.
Most bars are found parallel to the mainland area.

These are the panoramic depositional landforms of the coastal regions.

Now Hopefully you got the answer to all your question.
Next time whenever you get a chance to tour and visit around the coastal region and went to the beach,  also enjoy these mesmerizing landforms with fresh perception. 

And if you are already living in a coastal region then share your precious close review experiences with these depositional features of the coast.
