What are traces of ancient organisms have been preserved in rock?
They are generically called fossils.
What sedimentary rock is used to make cement?
Limestone is the sedimentary rock that is used to make cement. Some limestone is made of old coral reefs that have been buried by deposits.
Which rock was formed from skeleton and shells of sea animals and plants?
Coral is the hard rock-like substance that is formed by skeletons of tiny sea animals. These calcareous skeletons build up and form islands and reefs.
How are coral and limestone formed?
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.
Is dead coral a rock or a mineral?
a rock? i guess
What is a rock made of shells and corals cemented together?
Sedimentary rock is made from ancient coral reefs buried by sediments.
Another name for coral reefs?
The name for Coral Reefs are Sand bars,Atoll, Bank, Bar, Beach, Cay, Ridge,Rock, Rock barrier, Shoal, Skelly.
What type of rock is made up of ancient coral?
Over time coral reefs may be changed into a firm sedimentary rock, known as reef rock, and eventually into a dense, solid limestone. An example is the Coral Rag Formation around Oxford England. Some Coral Rag was used as a building stone. It can be seen in some of the oldest buildings in that city.
Is a petoskey stone a sedimentary rock?
Yes, a Petoskey stone is a type of sedimentary rock. It is formed from the remains of ancient coral reefs found in freshwater deposits in Michigan, USA. The stone is composed of fossilized coral, which gives it its distinct pattern.
What type of rock is coral?
No its a plant. Umm... the above answer is not true. Coral Reef is a biome = = Oh yes and if you were talking about the stuff that grow in coral reefs, they are made of many coral polyps which are very tiny animals.

What are the difference of corals and coral reefs?
A coral reef is a colony of corals. A coral reef can be formed on rock rubble, but old established coral reefs are actually structured out of dead coral. This is one of the reasons it takes so long for a reef to form. Some corals may life for tens or even hundreds of years before they die and allow another coral to grow on top of their skeleton. There are many types of coral reefs, but the real difference is that coral is what makes up a coral reef.
What is the ancient organism preserved in a rock is called what?
A fossil
What is a small low island on a coral reef called it has to begin with a K?
Key: Cay-pronounced "key" and often spelled that way-a small, low island. Key
Where do urchins live?
Sea urchins live in the sea, rock pools, kelp forests, and coral reefs
What kind of rock is corals?
Coral is actually a living thing, not a rock. Coral is not a rock at all. It is the skeletons created by anthozoans. These are a live organism. A rocklike deposit consisting of the calcareous skeletons secreted by various anthozoans. Coral deposits often accumulate to form reefs or islands in warm seas.
What types of rocks are found there at great barrier reef?
The reef sits on top of thousands of years of compacted coral skeletons that have compressed and fused to form limestone rocks. So yes, there are rocks in the reef as it is principally composed of rock.
