During a hurricane, how do reefs protect the shoreline?

• Cause upwelling, weakening tropical cyclones

• Cause waves to break out to sea, preventing shoreline erosion

• Prevent storm surge from occuring

• Act as a wind break, slowing gusts

Why are reefs considered areas of high primary productivity?

• The high number of different species in a small area

• The amount of photosynthesis from zooxanthellae

• The presence of nitrogen and phosphorus in large volumes

• The large amount of phytoplankton floating above the reef

What is the area between the shoreline and the reef called?

• Lagoon

• Bay

• Inlet

• Peninsula

Coral reefs are distributed in

• deep water with low nutrients in the tropics

• low nutrients with warm water

• in the ocean

• shallow tropical and low nutrient water

coral reefs need abiotic conditions including

• high oxygen, good light availability, consistent salinity, low nitrated and phosphates

• high oxygen, good light availability, low salinity, low nitrated and phosphates

• high oxygen, good light availability, consistent salinity, high nitrated and phosphates

• low oxygen, good light availability, consistent salinity, low nitrated and phosphate
