  • 4. BayCapeA large piece of land surrounded on three sides by water.A part of the sea partly enclosed by a curve in the land.
  • 5. PeninsulaA piece of land almost completely surrounded by water but joined to a large area of land.BeachA geological landform along the shoreline of a body of water.
  • 6. ThunderstormsSevere thunderstorms occur generally during the afternoon and evening hours.PrecipitationPrecipitation is high, particularly along the coast, and seasonal.TemperatureHot and humid.Average annual high temperature is about 77 degrees.
  • 7. Sandy soil is ideal for certain crops such as watermelons, peaches, coconuts etcSaline soil contains high level of salts which is ideal for growing date palm,sugar beet, cotton etc.
  • 8. Mangrove soil: Bacterium from mangrove soil helps in the fermentation ofmangrove trees.Peat soil- Soil that is derived completely from the decomposing remains of plants.They are used for horticulture and for growing crops.
  • 9. Coral reefsRocky structures are produced by living organisms found in marine waterswith little or no nutrients.Coral reefs are warm, clear, shallow ocean habitats that are rich inplant and animal life.
  • 10. Mangrove forestsThe forests transfer organic matter and energy from the land to thesea, forming the base for many marine food webs.They play a vital role in trapping sediments,thereby stabilizing coastlines and protecting coral reefs and sea grass.
  • 11. WILDLIFECoastal environment supports a large number ofmigratory and breeding birds.The coasts of Northern Europe are home for the Puffin.Chough are found around coasts in West Wales.Eider Duck are found in the Northern coasts of Europe, North America in large numbers.

  • 13. Humpback Whales can be seen off Washingtons coast,in Mexico and Hawaii.Humpback Whales
  • 14. Grass TreesOyster Plant Big Cone PlantExposed places on the coast are the flourishing grounds forbeautiful and sea-tolerant plants…
  • 15. 60 per cent of the world’s population lives within 60 km of a coast.Some grew up around fishing communities.Most coastal settlements have developed around docks, ports and harbours.Some grew up around tourist hotspots.
  • 16. Salt PansShallow man-made ponds are designed to produce salt from sea water.Notable salt ponds include the San Francisco Bay salt ponds in theUnited States, Little Rann of Kutch in Indiaand the Dead Sea salt ponds in Israel.
  • 17. Inland FarmingCoastline with its many inlets, peninsulas and offshore islands providesplenty of habitat for coastal floras.Palm Trees Black BerrysSea Oats
  • 18. The tropical monsoon climate and fertile soils of the coastal plains favour spicefarming.In fact, Asia is known as the ‘Land of Spices’ .Thirteen major spices are produced in Asia.Spice FarmingBlack Pepper Clove Cardamom

  • 24. Many of the World’s major cities such as New York, Sydney, Shanghai,Mumbai etc. lie on the coast.Coastal cities are the routes through which vital supplies of food,petroleum and raw materials for industry enter a country.
  • 25. The life of a coastal resident is vulnerable to natural disasters such as storms,cyclone, hurricanes, land erosion, etc.Shore line erosion
  • 26. The ultimate recipients of marine pollution due to industrial effluents, human activities etc.People face extreme possible impacts of climate change e.g. floods, tsunamis etc.Tsunami, 26 December Impact of Coastal Flood
  • 27. Coasts are facing environmental challenges related to human-induced activities.There are various sources of pollution such as garbage and industrial debris,oil spills from petroleum tankers etc.Coastal Pollution
  • 28. Climate ChangeContributes in rise of sea level, which threatens coastal habitat.Extinction of FishesDue to habitat degradation, over fishing and climate change.
