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.

Is it true deposits were formed when ancient seas evaporated?
Yes, in some areas in the past there were shallow seas in hot, desert environments which periodically flooded and evaporated, leaving deposits of various salts such as halite and anhydrite which were then buried by other sediments. Some of these deposits are now mined for the various salts.
Which fossil fuel was formed from the remains of small animals algae and other organisms that lived in oceans and shallow inland seas?
it is gas and oil
From what rock is sandstone formed?
Sandstone is formed of layers of eroded rock grains deposited in shallow seas. Under immense pressure, the grains eventually become sandstone. Sandstone comes in many colors. Red sandstone is colored by iron oxide.
Do All Limestone Look The Same?
Limestone is a sedimentary rock that is half calcium carbonate, and varies in types. It generally has a rough appearance, that is generally hard. It is light in color usually colored from grey to yellow.
What might stop the development of an organic sedimentary rock?
A sedimentary rock is one that is formed from sediments laid down in horizontal strata, usual at the bottom of lakes or shallow seas. But they can be formed on land, such as Old Red Sandstone, which is a remnant of an ancient hot desert.An "organic" sedimentary rock is one made up not from mineral sediments such as sand and mud, but from the skeletal remains of sea-creatures or from partially decayed plant remains (coal). It follows that organic sedimentary rock will always be formed under water. (The skeletons are mineral, typically calcium carbonate). An example is limestone, which may be carboniferous, oolitic, or chalk.To answer the question, the factors that might stop the development of an organic sedimentary rock include: extinction of the species, loss of sea-life through climate change, or the drying up of the ocean through land uplift. Even an ice-age might affect the process.
Why do you find limestone in South Dakota when it is typically formed in the oceans?
Millions of years ago, the area now known as South Dakota was covered by seas. The shells and skeletons of the animals which lived in the seas formed the limestone that is now found in South Dakota.
Do we get limestone from volcano?
No, we don't. Limestone is a sedimentary rock laid down in ancient seas. It is formed from the skeletal remains of countless marine creatures.
When was ...In Shallow Seas We Sail created?

Where did you probably find a deposit of limestone what type of setting did it form in?
Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.
How old and how was quartzite formed in the Dover Cliffs of England?
deposits of volcanic ash in the shallow seas during the deposition of the chalk
Where was limestone originally formed?
Limestone is the skeletal remains of small marine shelled creatures. Their remains sank to the floor of the seas, and the layers became rock over a very long time.
When was dolphins found?
Most Dolphins are found in all oceans, they are found in the shallow seas.
Are limestone deposits are often evidence of ancient tropical seas?
Many geologists believe that limestone deposits on land exist where ancient seas used to be. The moisture, over many centuries, created limestone.

How geologist know that shallow seas coverd the central part of north America?
The limestone. It is only deposited in the presence of water. Most of the fossils found are marine animals. There are coal, slate and shale deposits formed from river or shallow lagoons as evidence of shallow water. And the mountains came after because sedimentary rock is laid flat. The mountains forming the Appalachian mountains are very eroded so they must be very old. Of course this is only the simple explanation visit wiki or a library for more info.
Are limestone deposits evidence of ancient seas?
Limestone is a type of sedimentary rock comprised of minerals calcite and aragonite. Limestone deposits are evidence of ancient seas with some limestone being dated as far back as 470 million years ago on the area where North America now stands.
Where is a sea horse located?
shallow seas and temperate waters
