Limestones are only formed from the remains of once-living creatures?

While limestone is mostly composed of the skeletal fragments of deceased marine life, that is not the only component. Limestone also contains traces of clay, sand, and silt. Limestone can also be created by precipitating calcite or aragonite.

How do organic sedimentary rocks forms?
from dead plants
How are oil and natural gases formed?
from the rotting remains of tiny sea creatures that lived millions of years ago
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.
What kinds of sediments form limestones?
Limestone is rock that formed at the bottom of the sea from the shells, bones, and bodies of fish, crabs, shellfish and other marine life. Because it's from life, it's called organic. Chalk and marble are similar.
Where did natural gas start?
Natural gas (and oil) is formed from the fossilized organic remains of sea creatures that were trapped in rocks at the bottom of the sea as sediments accumulated.

What type of fuel formed by the remains of sea creatures and plants millions of years ago?
fossil fuel
How do rocks form from remains of animals?
Limestone is formed from the skeletal remains of minute sea creatures, laid down on the sea floor millions of years ago.

Is limestone sedimenrtry or igneas?
limestones are sedimentery rocks because it is formed by layers.
Is lime stone sedimentary?
Lime stone is a sedimentary rock formed by the skeleton remains of ancient minute sea creatures.

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.
Why are coal and limestone classified as organic sedimentary rocks?
Because coal and most limestones are formed from organic material (living things). Coal is formed from compressed plant material, and limestone from animal remains (hard parts: soft parts are almost always rotted, broken by force or consumed by predators). From here you get different kinds of coal, depending on how long and how deep they have been buried. Limestones vary according to their composition (through formation). 'Shelly limestone' is composed of shell, as the name suggests. Chalk is composed of coccoliths - minuscule shell of tiny sea creatures millions of years ago. These rocks are, therefore, fossils.
What was formed from the remains of living things?
It is recycled: it either returns to the soil as compost, or forms the energy source for creatures further up the food chain.
Where did natural gas start?
Natural gas (and oil) is formed from the fossilized organic remains of sea creatures that were trapped in rocks at the bottom of the sea as sediments accumulated.
