Factors contributing to coastal erosion:
Waves, Storms, Rising sea levels, changes in how sand and sediment move, human activities such as building near coast, and natural processes like wind and water wearing down rocks.
What is a Shoreline?
This refers to the edge where the land meets the water.
What is erosion?
Erosion is the process of wearing away or breaking down of soil, rock, or land surfaces by natural forces like water, wind, ice, and gravity.
What are coastal zones?
Coastal zones are the areas where land meets the sea, including beaches, estuaries, cliffs, dunes, and tidal marshes.
List some erosional shores.
Sea cliffs, Wave-Cut platforms, Sea Arches, sea Stacks, Caves and Caverns.
Why is our climate changing so much?
It’s caused by humans
What is The Coastal Erosion?
Coastal Erosion is wearing away of land and the removal of beach or dune sediments by wave action, tidal currents, wave currents, drainage or high winds.
What are some natural causes of erosion?
Rain, rivers, wind, flooding from extreme weather, ocean waves, and the movement of ice (glaciers). Steep slopes, formed by the uplift or sinking of land, can result in landslides.
How do coastal zones contribute to biodiversity?
Coastal zones support rich biodiversity by providing habitats for various marine and terrestrial species, including fish, seabirds, marine mammals, turtles, mangroves, seagrasses, and coral reefs.
How can we prevent erosion?
building jetties and seawalls help prevent erosion... They do help prevent it in a localized area but this often just shifts the erosion elsewhere. Planting vegetation can be helpful as they help keep sand in place by providing a better structure for it to “hold on to”
What is a barrier island?
A barrier island is a long, narrow island that runs parallel to the mainland and helps protect the mainland from the ocean's waves and storms.
What is Marine sub-system?
the ocean component of a coastal zone
What are some human causes of Erosion?
Deforestation, habitat loss, and agricultural activities.
What are Saltmarshes?
Saltmarshes are coastal wetlands flooded by saltwater from tides, with specialized plants and habitats.
What is weathering, and how is it different from erosion?
Weathering is when rocks break down naturally over time, while erosion is when those broken rocks and soil get moved to another place by water, wind, or ice.
List two Abiotic Factors Of Rocky Shores
Water and Rocks or Salinity
A coastal zone is a area between…
Land and Water
How does erosion impact the environment?
Erosion can lead to loss of fertile soil, sedimentation in water bodies (which affects aquatic life), landslides, changes in landscape features, and degradation of habitats for plants and animals.
What are the main features of coastal zones?
Coastal zones have diverse features such as sandy beaches, rocky shorelines, tidal flats, mangrove forests, and coral reefs.
What are some human activities that contribute to erosion?
Deforestation, overgrazing by livestock, improper agricultural practices like monoculture and excessive tilling, urbanization without proper erosion control measures, and mining are human activities that accelerate erosion.
What is a Estuarine?
Estuaries are where rivers meet the sea, creating a mix of freshwater and saltwater habitats.
Coastal Zone is composed of 3 subsystems:
How does water cause erosion?
Water erosion occurs when rainfall, rivers, or ocean waves move soil particles and rocks, gradually wearing away the land and creating features like valleys, canyons, and riverbanks.
What’s a tide pool?
A tide pool is like a small bathtub of ocean water that forms when the tide goes out. It's usually in rocky areas along the shore. Lots of sea creatures live in these pools until the tide comes back in, bringing fresh seawater with it.
What are Dikes?
Dikes are like sea walls that extend into land rather than out to sea. They guide the water in and extend up to block water from flowing over into communities
