What is Hydraulic action?
The weight and impact of water against the coastline which cause cracks/caves to form.

Coral Reefs are found in shallow, clear, warm water because there is
lots of sunlight for the symbiotic algae (zooxanthellae) that live with the polyps

Which of the mangrove trees are found the furthest back from the shore?
red
white

How do mangroves help protect humans from hurricanes and tsunanis?
They release salt into the air, which neutralizes these events.
The birds, animals, and fish in the mangroves get killed instead of the humans.
They absorb up to 90% of the impact of these events.

Groynes are an effective technique because they slow down the process of what occurring?

Deposition
How do groynes work to protect the coastline?
They trap sediment by slowing down longshore drift, thereby building up a wide beach
They absorb wave energy so that the cliffs behind are protected
They act as a hard rock barrier at foot of cliff to provide a buffer again the sea
They allow rapid longshore drift along the coastline
