Quarrying is a form of mining and is also known as open pit mining. When minerals are found deep below the surface, a deep mine has to be dug to extract them. Quarries are usually dug deeper and larger, until the mineral resource is exhausted. When they are no longer used, quarries are often used as landfill sites for the disposal of waste.

Acid rain damages buildings, monuments and statues especially those made of limestone and marble as they contain large amounts of calcium carbonates. The calcium compounds react with the acid in the rain, damaging them. Exhaust gases from the Mathura Refinery greatly affected the Taj Mahal at Agra.
Limestone is a sedimentary rock, mainly composed of mineral calcite. The primary source of the calcite is usually marine organisms, which settle out of the water column and are deposited on the ocean floors as pelagic[?] ooze (but see lysocline for information on calcite dissolution).
