Coral reefs are built by millions of coral polyps, small colonial animals resembling overturned jellyfish. They excrete an exoskeleton made of calcium carbonate, which forms their distinctive shapes as a colony. Thousands of coral colonies build up over time to form the reef.
After an extensive period of time, the reef may die off, perhaps because the conditions of the environment change for the worse for the corals. Since reefs often form in conditions where there is a lot of water movement (because the water is more oxygenated in these areas), if the colony is no longer being sustained by living polyps the colonies break up. Reefs can still break up when the coral is still alive if the conditions are severe. Sedimentation and cementation occurs as calcium carbonate precipitates out of the water and of the exoskeletons of the coral.

How is coral limestone different from other types of limestone?
Coral limestone is formed almost completely from the calcitic skeletons of individual coral polyp colonies. Other limestones can be formed from the shells of marine organisms or be formed from the precipitation of calcite from a saturated solution, or a combination of the two. Chemically, they're pretty much the same.
What is a rock formed from crushed shells and coral?
A Sedimentary Rock. Eg, Bioclastic Limestone.
A deposit of organic limestone on land probably formed millions of years ago as a?
Coral reef
Why is most limestone formed in shallow warm seas?
Limestone is mostly made up of fossilized coral piled and compressed by the weight of the ocean over millions of years. Coral require sunlight for photosynthesis so cannont grow in deep water. Also, coral does better in warm regions. Limestone is found where coral is successful. Warm, shallow water.
How is cement formed from limestone?
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
Were the Bahamas formed by coral?
no it was formed by limestone
Islands formed by limestone animal skeletons?
Coral island.

What is sedimentary rock formed from deposites of shells?
Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.
What is the underwater buildup of limestone skeletons from certain small animals?
This is how coral reefs are formed. Coral will take salt from the sea and utilize it to create limestone skeletons on underwater objects.

What type of sedimentary rock formed from the remains of coral and sea shells?
Limestone and chalk.
Where is limestone quarried?
Limestone is often sedimentary, formed of calcite in the form of shells and coral. So it's found where there used to be an ocean.
What is a good sentence for limestone?
Limestone is a sedimentary rock formed from the accumulation of skeletal fragments of marine organisms like coral and mollusks.
What Sedimentary rock formed from deposits of shell?
Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.
A deposit of organic limestone on land probably formed millions of years ago as a?
