Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.

How is cement formed from limestone?
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
What is required for karst topography to form?
Karst topography is formed by chemical weathering, and affects the underlying carbonate rock (limestone or dolomite). This occurs under specific drainage conditions. Slightly acidic water (carbonic acid in solution) is the active agent.
How is limestone pavement formed?
limestone pavement is formed by leaving exposed limestone for ages
A sedimentary rock that is sometimes formed by deposits of shell fragments?
A sedimentary rock that is sometimes formed by deposits of shell fragments is LIMESTONE!!
What is a rare and beautiful metimorphic stone is formed of limestone?
Marble is metamorphosed limestone.
What type of rock is formed by putting limestone under heat and pressure?
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
When is Limestone formed?
Different limestone deposits have formed at many stages in the Earth's gological history, such as the Carnoniferous and Jurassic, and in suitable conditions,limestone is forming now.
what kind of rock is formed under clam water conditions near the shore?
Various sedimentary rocks but particularly Limestone and Sandstone.
What does Limestone under certain conditions may undergo a metamorphosis?
"Limestone, under certain conditions, may become marble". -Getis Introduction to Geography.
What rock is formed when limestone goes under metamorphic change?
Marble is a rock formed by the metamorphism of limestone.
How is cement formed from limestone?
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
How is concrete formed from limestone?
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
Is limestone rounded or jagged?
Depends on what kind of conditions it has been under.

How do stalactites in limestone caverns most likely form?
The limestone caverns themselves are formed by groundwater gradually dissolving the limestone rock. In this process, some of the limestone is taken into solution, and under favourable conditions, it will form a drip on the roof of a cavern. This may eventually build to form a stalactite above, and perhaps also a stalagmite below it.
