sedimentary rock

Limestone is a sort of sedimentary rock. Approximately 10% of sedimentary rocks are limestones. The solubility of limestone in water and vulnerable acid answers ends in karst landscapes in which water erodes the limestone over lots to millions of years.

Where is sandstone and limestone found?

Formation of Limestone and Sandstone

Limestone is found in beds and most limestone beds form in marine environments in which big deposits of organisms and carbonate precipitation build up over the years like an ocean or large lake.

Is limestone better than sandstone?

When it comes to texture limestone and sandstone are quite different. Limestone tends to be flatter and smoother with less ridges in its finish. Consequently this even finish means it’s ideal for driveways and also many indoor purposes too. … Sandstone on the other hand is slightly more uneven with a rippled texture.

Limestone is so versatile that this rock is used in more ways than any other. It is a low value material per ton perhaps only slightly more than standard aggregate rock but it is important in many products.

What happens when you burn limestone?

When limestone is heated in a kiln the calcium carbonate breaks down into calcium oxide and carbon dioxide. This type of reaction is called thermal decomposition. … Once burnt limestone turns into calcium oxide which is known as quicklime.
