Is limestone made from seashells?
Limestone is made up out of fossils of corals and shells from the water.
What is the temperature for corals to survive in?
Usually 72 - 76 degrees F, but most corals prefer different temps, when answering this question it depends on if it is soft corals or hard corals, but this is the average temp
Are soft corals food for other organisms?
Yes, soft corals can be food for certain organisms such as certain shrimp, snails, and nudibranchs. Some fish species may also feed on soft corals as part of their diet.
When did corals evolve?
Although corals first appeared in the Cambrian period, some 542 million years ago, fossils are extremely rare until the Ordovician period, 100 million years later, when rugose and tabulate corals became widespread.
Which observation best shows that limestone was formed from ocean sediments?
The presence of marine fossils within the limestone is the best observation that shows it was formed from ocean sediments. Marine fossils like shells, corals, or sea creatures preserved within the rock provide direct evidence of its marine origin. Additionally, the presence of ripple marks or cross-bedding in the limestone can also indicate its formation in a marine environment.
Do Corals Coral stop growing when they get to a sertane size?
Like most fish, corals do not have a certain size that they stop growing there for, they will continue to grow. Most corals do slow down when they get huge sizes but never stop.
What is the ideal ocean temperature for the growth of reef-building corals?
about 75 degrees Fahrenheit
What mineral is found in the shells of certain animals such as corals and clams?
Aragonite, a carbonate mineral.
What is constructed primarily from the skeletal remains and secretions of corals and certain algae?
A coral reef.
What does a coral reef need?
Corals cannot flourish with opaque water. With this, they need clear water for them to get sunlight to do well. They also need warm temperature specially the reef-building corals.
Where do the corals occur?
it occurs between the tropic where the temperature is at least 21 degrees centigrade. the waters should not be deep because the corals need sunlight to grow. in deep waters sun light doesnt penetrate. so temperature and shallow water are ideal conditions for the corals to grow. this mainly happens between the tropic i.e tropic of cancer and tropic of capricon.
Which is a biochemical rock that contains fossils?
Limestone is a biochemical rock that can contain fossils. It is formed from the accumulation of calcite or aragonite shells or skeletal fragments of organisms such as corals, foraminifera, and mollusks. Over time, these remains can be compressed and preserved in the rock.
