What is coral bleaching
Coral bleaching is the loss of symbiotic algae from the tissue of corals as a result of environmental factors.
|
What is ahermatypic?
Soft corals that do not build reefs.
|
What is how many types of reefs are there? must name them all.
(4) Fringing reefs, barrier reefs, atolls, patch reefs.
|
What is typically found between fringing reefs and barrier reefs?
Patch reefs.
|
What is the age of most coral reefs?
Between 5000 and 10000 years old.
|
What is the name of the special phylum that all corals belong to?
Cnidarians
|
What is hermatypic?
Hard corals capable of reef building
|
What is the name of the person who studied the geomorphology of coral reefs stated in unit 5?
Darwin
|
What is a patch reef?
Small, isolated reef usually located within the lagoon of a barrier reef.
|
What is reef erosion?
The gradual wearing away of a coral reef by the action of living organisms and physical factors such as storms.
|
What is polyps?
The sessile life stage of coral animals
|
What is the purpose of limestone skeleton
Provides the framework of coral reefs.
|
What is fringing reefs separated from the shorelines by?
Narrow shallow lagoon.

Patch reefs,
|
What is two fish mentioned in unit 5 that are considered predators of coral polyps?
Parrot fish Butterfly fish
|
What is the form in which corals reproduce? name the process too
Asexually through a process called budding.
|
What is the reason why zooxanthellae perform photosynthesis?
To generate organic material that can then be passed on to the coral.
|
What is which two types of reefs lie along the shoreline of a larger landmass
Barrier reefs and fringing reefs.
|
What is who determined how atolls were formed?
Darwin.
|
What is physical causes of reef erosion?
Storms, exposure to air and ocean acidification.
|
What is in a relationship between coral and zooxznthellae where does the zooxanthellae live?
In the corals tissue
|
What is the symbiotic relationship coral and zooxanthellae have?
Mutualistic.
|
What is geomorphology
The study of the characteristics, origin and development of land forms.
|
What is the size in diameter that atolls vary?
1-32 km
|
What is ocean acidification?
A reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon from the atmosphere.
