Yes, coral reefs are made of the limestone skeletons of deceased corals - the living corals are on the surface of the reef.

When coral animals die do their skeletons fall to the sea floor?
When coral animals die their skeletons do indeed fall to the sea floor. This is the only place where they can go.
When coral animals die their skeletons fall to the sea floor.?
Yes, they do.
How does coral make calcium carbonate?
The skeletons of dead corals are the foundation upon which layerer upon layer of successively younger animals attach themselves. The coral animal, or polyp, is colulmn shaped. Its lower end is attached to the hard floor made of the preceding coral skeletons of the reef, and its upper end extends into the water. There hard and soft corals, depending on the type of skeleton secreted. The hard-coral polyp deposits a cup-like solid skeleton of calcium carbonate around itself into which the polyp withdraws during the daytime. For this reason, deep sea divers see only the skeletons-and not the polyps-of hard corals.
Do skeletons exist on the ocean floor?
The ocean floor sediment contains unfathomable numbers of marine organism skeletons.
What is limestone and chert?
Limestone is a boigenic rock. It is formed as a byproduct of living things, frequently it is made from the calcareous skeletons of living creatures. If we take the Chalk as a limestone, this was made in a warm shallow sea from the shells of microscopic plankton as they died and sank to the sea floor. However along with the calcareous shells, there were also shells of diatomic plankton which are made out of silicon dioxide (quartz). After deposition as the chalk was compacted by the overlying sediments that were laid down on top of it and it became buried, the water it contained became heated and the skeletons of the silicious diatoms dissolved in the water and then were redeposited as layers of "Chert" or "Flint" in the Chalk.
Under what conditions is limestone formed?
Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.
Why are diatom shells found in ocean-floor sediments?
diatom shells settle on the ocean floor from the surface
Where do you get limestones from?
Limestone is a sedimentary rock formed of Calcium Carbonate (CaCO3) and Magnesium. Most limestone forms from the skeletal remains of various algae, phytoplanton, and shellfish. it can also be made into fireplaces and all sorts of stuff . :)
Are there shells in an ocean floor?
i just did this to tell everyone that this page sucks
