Coasts

How does the sea and wind erode, transport, and deposit?

• Erosion occurs when the sea and wind build up rocks and particles. Transportation happens through processes like longshore drift and suspension. Deposition occurs when the energy of the sea and wind decreases, leading to the formation of various landforms.

• Erosion occurs as the sea and wind break down rocks and carry away particles. Transportation is mainly done through volcanic activity. Deposition occurs when the energy of the sea and wind decreases, leading to the formation of various landforms.

Under what conditions do coral reefs and mangroves form?

• • Coral Reefs: Form in warm, clear, shallow, and nutrient-poor waters with hard substrates and gentle water movement. They rely on stable temperature and salinity conditions and need light for photosynthesis.

  • Mangrove Forests: Grow in tropical and subtropical intertidal zones where they tolerate saline and muddy conditions. They thrive in sheltered areas with low wave action.

• • Coral Reefs: Form in cold temperatures, high nutrient levels, turbid waters, soft substrates, strong wave action. They rely on stable temperature and salinity conditions and need light for photosynthesis by symbiotic algae.

  • Mangrove Forests Form in cold temperatures, clear water, stable water levels, well-drained soils, high wave action, and low salinity, with adaptations to cope with periodic flooding and anoxic soils..

• Coral reefs form in freshwater lakes while mangroves form in mountainous regions. while mangroves form in tropical coastal areas with sediment and wave protection.
