Limestone is made of calcium carbonate. Around 1.8 billion years ago the sea started to oxidize because cyanobacteria produced carbon dioxide. Calcium ions could be easily found because protists used them. Thus calcium carbonate was easy to make after the seas were oxidized
Limestone deposits became common 1.8 billion years ago due to the accumulation of calcium carbonate shells and skeletons from marine organisms. This period saw an increase in the development of multicellular life forms that produced calcium carbonate as part of their biological processes, leading to the formation of limestone deposits through sedimentation and compaction over time.

A sedimentary rock that is sometimes formed by deposits of shell fragments?
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
What sedimentary rock is used to make cement?
Limestone is a common sedimentary rock used to make cement. It is primarily composed of calcium carbonate and is crushed and heated to form the powdery substance used in cement production.
Why most caves form by limestone?
Limestone is susceptible to dissolution by acidic water, which is common in most natural environments. Over time, this dissolution process carves out cavities underground, leading to the formation of caves. Additionally, limestone is a common and widespread rock type, which contributes to the prevalence of limestone caves.
What do limestone shale and sandstone have in common?
Limestone, shale, and sandstone are all sedimentary rocks formed through the accumulation and compression of sediments. They are all composed of mineral particles such as quartz, calcite, and clay minerals. Additionally, these rocks are commonly used in construction and as building materials due to their durability and strength.
What is Another name for limestone?
One common name for limestone is calcium carbonate.
A sedimentary rock that is sometimes formed by deposits of shell fragments?
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
What is the common name for limestone?
The common name for limestone is simply "limestone".
Karst areas which are characterized by sinkholes are common in parts of the southeast United States Where do Karst areas often form?
Above limestone deposits
What are some type of rocks found in TN?
Some common types of rocks found in Tennessee include limestone, sandstone, shale, and dolomite. Additionally, Tennessee is known for its rich deposits of minerals such as coal, zinc, and copper.
Is Florida known for sinkholes?
Yes, Florida is known for sinkholes due to its karst topography, characterized by the dissolution of soluble rocks such as limestone, causing the ground to collapse. Sinkholes are relatively common in Florida, particularly in areas with underlying limestone deposits.
What type rocks are found in Belize?
The most common rocks found in Belize are limestone and sandstone, as the country is known for its extensive limestone deposits. These rocks are typically found in the Maya Mountains and the Belize Barrier Reef. Additionally, some volcanic rocks can also be found in Belize, particularly in the southern region near the border with Guatemala.
What is the most common rock in cork?
The most common rock in Cork, Ireland is limestone. The region is known for its extensive deposits of limestone, which is a sedimentary rock formed from the remains of marine organisms. It is widely used in construction and as a building material in the area.
What sedimentary rock is used to make cement?
Limestone is a common sedimentary rock used to make cement. It is primarily composed of calcium carbonate and is crushed and heated to form the powdery substance used in cement production.
How do you write 1 billion in figures?
Depending on the country, a "billion" is either 1,000,000,000, or 1,000,000,000,000. The smaller version is become more common, though.
Limestone deposit hanging from the ceiling ofa cave?
A limestone deposit hanging from the ceiling of a cave is known as a stalactite. Stalactites form when mineral-rich water drips from the ceiling and leaves behind mineral deposits that gradually build up over time, creating a cone-shaped structure that hangs down. Stalactites are common in caves with limestone formations.
Where is fluorite most common?
Fluorite is most commonly found in places with hydrothermal veins, such as in limestone and dolostone deposits, as well as in areas with granite and other igneous rocks. It is also often associated with areas where there are deposits of lead, zinc, and silver ores. Some notable locations for fluorite deposits include China, Mexico, and the United States.
What special property does limestone have in common with marble?
Both limestone and marble have calcium in them.
