What was the era when most of our limestone and coal formed?
Most of our limestone and coal formed during the Carboniferous period, which lasted from about 359 to 299 million years ago. This era was characterized by lush, swampy environments that supported dense forests and abundant plant life, leading to the accumulation of organic material that eventually transformed into coal. Additionally, limestone formation was facilitated by the marine environments of the time, where calcium-rich organisms thrived.
What was the time period when most of our limestone and coal formed?
Most of the limestone and coal that we use today formed during the Paleozoic Era, particularly in the Carboniferous Period, which lasted from approximately 359 to 299 million years ago. During this time, tropical swamps and shallow seas were prevalent, creating the ideal conditions for limestone and coal deposits. The accumulation of plant material in these swamps eventually transformed into coal, while marine organisms contributed to limestone formation.
What are two important important organic rocks?
Limestone and coal are two important organic rocks.
Which rock most likely formed as a result of biological processes?
Limestone is a rock that often forms as a result of biological processes, as it is made up of calcium carbonate derived from the skeletons of marine organisms like corals and mollusks.
What is a kind of organic sedimentary rock formed from the decayed remains of plants a sandstone b limestone c shale or d coal?
Coal is the only option being a solely organic product. Sandstone, Limestone and Shales may contain considerable amounts of coalified organic matter of marine or continental origin (up to several per cent) but the larger fraction of material is detrital slicates in the case of sandstones and shales and carbonates in the case of a limestone.
What era did most of our limestone and coal formed?
Most of our limestone formed during the Paleozoic era, approximately 500 to 250 million years ago. Coal formation occurred mainly during the Carboniferous period within the Paleozoic era, around 360 to 300 million years ago.

Limestone and coal are two important organic rocks.
When most of your limestone and coal formed?
Limestone typically formed during the Paleozoic era (around 540 to 250 million years ago) when large quantities of marine organisms such as corals and mollusks accumulated on the sea floor and compressed over time. Coal formed primarily during the Carboniferous period (around 360 to 300 million years ago) when dense forests in swampy environments underwent burial and transformation into coal due to pressure and heat.
How are coal and limestone similar to each other?
Coal and limestone are both sedimentary rocks that are formed from the accumulation of organic material (coal) or calcium carbonate (limestone) over millions of years. Both are used as natural resources in various industries, with coal being primarily used for energy production and limestone used in construction, agriculture, and manufacturing.
What era was the coal forest formed?
Carboniferous and Permian
What period were carbons formed in the Earth?
Hydrocarbons and coal were formed in what is known as the carboniferous era.
How are coal and limestone different?
Coal is a combustible sedimentary rock formed from the remains of plants and trees, used as a fuel source. Limestone is a sedimentary rock made mostly of calcium carbonate, used in construction and manufacturing. Both have different origins, compositions, and uses.
Match the era on the left with its characteristic on the right?
Precambarian- When earth’s atmosphere formed Mesozoic- Ended with a massive impact Paleozoic- When oxygen-breathing organisms first thrived Cenozoic- Began about 65 million years ago Hope this helps! :)
What is a sedimentary rock formed from materials that were once living?
A sedimentary rock formed from materials that were once living is called organic sedimentary rock. Examples include limestone, coal, and chalk, which are composed of the remains of marine organisms, plants, or other organic matter.
How do the coal and limestone specimen differ in appearance?
Coal is easily seen as black. Limestone is usually gray. Coal has no real features to it. Limestone has shells, and other things.
