Limestone, coquina, and chalk are all sedimentary rocks primarily composed of calcium carbonate (CaCO3). They are formed from the accumulation of organic materials, such as shells and coral, or from the precipitation of calcium carbonate from water. Additionally, these rocks often indicate ancient marine environments, as they typically originate in oceanic or coastal settings. Their composition and formation processes highlight the geological history of sedimentary environments.

What is the relationship between limestone marble and chalk?
Limestone, marble, and chalk are all types of sedimentary rocks composed mainly of calcite. Limestone is the precursor to marble when subjected to high pressure and temperature. Chalk is a softer form of limestone made up of microscopic marine organisms.
Which two rocks have similar composition to limestone?
Dolomite and chalk have similar compositions to limestone, as they are all primarily composed of calcium carbonate minerals. Dolomite contains a significant amount of magnesium carbonate in addition to calcium carbonate, while chalk is a type of limestone that is formed from the shells of marine organisms.
What elements are found in limestone chalk and shells?
The element calcium is found in all four items.
How does coquina form?
Coquina forms when shells, mineral calcite, and sometimes phosphate settle on the bottom of the ocean, while more and more pile upon them as time passes. Soon, as more pressure builds up, all the shells, mineral calcite, and phosphate press together to create a hard structure in the form of a rock called coquina.
What rock type is in the River Tillingbourne?
Chalk, sands, clay, and glacial drift can all be found in an around the River Tillingbourne.
What do limestone chalk marble calcium carbonate have in common?
they all have differentlimestone'swhich makes them have something in common. :D by jessicaxxx
What 3 kinds of sedimentary rocks make up coquina?
Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
What is the relationship between limestone marble and chalk?
Limestone, marble, and chalk are all types of sedimentary rocks composed mainly of calcite. Limestone is the precursor to marble when subjected to high pressure and temperature. Chalk is a softer form of limestone made up of microscopic marine organisms.
What are the similarities between gneiss marble coquina and quartzite?
marble used to be limestone
What sedimentary rock forms marble?
Limestone or dolostone forms marble. This encompasses all types, from Chalk to Oolitic Limestone.

What do Chalk Marble and Limestone have in common?
Chalk, marble, and limestone are all sedimentary rocks composed primarily of calcium carbonate. They are formed from the accumulation of marine organisms, such as shells and coral, and share similar properties like their white color and susceptibility to erosion by acids.
What elements are found in limestone chalk and shells?
The element calcium is found in all four items.
What is the reaction between limestone and marble chalk?
Any chemical reaction ! You think probably to relation: all are forms of calcium carbonate - CaCO3.
How does acids break down rock?
It breaks down limestone, chemically acid rain is : H2CO3, it reacts with CaCO3 (limestone) to break it down. Limestone is effervescent with all acids, you can try it by adding lemon, vinegar, or any other acid to a chalk, you will notice hydrogen bubbles. :)
What is the Barefoot Pit on Route 31 in South Carolina?
It is a Coquina mine. Coquina is a sedimentary rock used primarily as a base for highway construction I Where is it all comming from ? ?
Which common minerals fizzes when dilute hydrochloric acid HCI is placed on it?
Calcite is a common mineral that will fizz when dilute hydrochloric acid (HCl) is placed on it. This reaction is due to the release of carbon dioxide gas from the mineral when it comes in contact with the acid.
