Which is the hardest granite clay chalk Jurassic limestone or carboniferous limestone?
Among granite, clay, chalk, Jurassic limestone, and Carboniferous limestone, granite is generally considered the hardest material. Granite is an igneous rock formed from the slow crystallization of magma, making it much denser and more durable than sedimentary rocks like chalk and limestone. Carboniferous limestone is relatively hard but not as tough as granite. Therefore, granite stands out as the hardest of these materials.
What era was when the limestone and coal formed?
Limestone and coal primarily formed during the Paleozoic and Mesozoic eras. Limestone typically originates from marine environments and is abundant in the Paleozoic era, particularly in the Carboniferous period. Coal formation is also closely associated with the Carboniferous period when extensive swampy environments allowed for the accumulation of plant material. Thus, both limestone and coal are significant geological features from the Paleozoic era, especially during its later stages.
What type of rock is carboniferous limestone?
Carboniferous limestone is a type of sedimentary rock that is formed from the accumulation of skeletal fragments of marine organisms such as corals and mollusks. It is typically composed of calcium carbonate and is known for its durability and suitability for building materials like aggregates and cement.
When most of our limestone and coal formed?
Most of the Earth's limestone formed during the Paleozoic Era, particularly in shallow marine environments, with significant deposits created during the Carboniferous period about 359 to 299 million years ago. Coal primarily formed during the Carboniferous period as well, when vast swampy forests existed, allowing for the accumulation of plant material that eventually transformed into coal over millions of years under heat and pressure. These processes collectively contributed to the substantial fossil fuel reserves we rely on today.
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 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.

How is concrete formed from limestone?
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!

Which period did the redwall limestone form?
The Redwall Limestone formed during the Mississippian period, which is part of the Carboniferous era. This period lasted from about 359 to 323 million years ago. The limestone is primarily found in the Grand Canyon region and is known for its rich fossil content, including marine organisms that thrived in shallow seas at the time.
What era was the coal forest formed?
Carboniferous and Permian
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.
Why is the marble arch caves called that when they are made from limestone?
Simply a romantic name. Similarly with "Marble Steps Pot" in the Carboniferous Limestone of the Pennines of NW Yorkshire.
What period were carbons formed in the Earth?
Hydrocarbons and coal were formed in what is known as the carboniferous era.
