Marble is made from limestone....
Egypt's pyramids and Sphinx are made of limestone....

Answer 2

Limestone is the most abundant of the non-clastic sedimentary rocks. Limestone is produced from the mineral calcite (calcium carbonate) and sediment. The main source of limestone is the limy ooze formed in the ocean. The calcium carbonate can be precipitated from ocean water or it can be formed from sea creatures that secrete lime such as algae and coral.
Chalk is another type of limestone that is made up of very small single-celled organisms. Chalk is usually white or gray in color.

Answer 3

Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). Limestones often contain variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand as disseminations, nodules, or layers within the rock. The primary source of the calcite in limestone is most commonly marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze or alternatively is conglomerated in a coral reef (see lysocline for information on calcite dissolution). Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites and stalactites. Another form taken by calcite is that of oolites (oolitic limestone) which can be recognised by its granular appearance. Limestone makes up about 10 percent of the total volume of all sedimentary rocks.

Pure limestones are white or almost white. Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces. Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock. Folk and Dunham classifications are used to describe limestones more precisely.

Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls and around hot or cold springs. Calcium carbonate is deposited where evaporation of the water leaves a solution that is supersaturated with chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls. Coquina is a poorly consolidated limestone composed of pieces of coral or shells.

During regional metamorphism that occurs during the mountain building process (orogeny) limestone recrystallizes into marble

Answer 4

Limestone rocks are sedimentary rocks that are made from the mineral calcite which came from the beds of evaporated seas and lakes and from sea animal shells. This rock is used in concrete and is an excellent building stone for humid regions

Answer 5

This sample of limestone has a large fossil in it. This happens all the time since limestone is made of shells and dead sea creatures that collect at the bottom of the ocean. They get buried by other sediment and, after millions of years of being under pressure, the particles get cemented together to form solid rock. Limestone is a very strong rock and is often cut into large blocks and used in the construction of buildings and skyscrapers. Crushed limestone is also used to make cement, plaster and chalk.
Limestone fizzes in vinegar, which means that it reacts to acids. This also means that the outsides of many of our buildings and monuments are being affected by acid rain. Acid rain occurs when large companies pollute the air by releasing chemicals like sulfur into the atmosphere. The sulfur combines with hydrogen and oxygen in the air to form sulfuric acid!

When limestone undergoes metamorphism, it turns into marble. If the limestone contains other materials such as sand and clay, the calcite will react with them to produce minerals such as tremolite, epidote, diopside, and grossular garnet.

Answer 6

Limestone is a rock composed mainly of calcite (calcium carbonate). Limestones can be classified according to observed properties. Try a web search for the names of "Folk" and "Dunham" to find common classifications.

Answer 7

limestone rock

Answer 8

listen to your question you answered yourself what kinds of Rock is LIMESTONE made of? limestone is made from limestone

Answer 9

Hmmm I,m no geologist but I believe the answer would be limestone.

Answer 10

sedimentary rock. the other types of rock are igneous and metamorphic
