When cut and polished, it gives a very smooth surface. Pure marble is white in color. Some impurities present in the marble appear as a spot or a streak of different color. Taj Mahal is built up of white marble.

Granite, marble, sand stone, pumice, slate stone and precious stones are different types of rock. Granite is the hard grey stone used I construction work for foundation and walls of buildings, in construction of dams etc.

Too much of quarrying will lead to degradation of the environment.  

Marble is a white hard stone mainly containing calcium carbonate. It is generally used for sculptures and for buildings. When cut and polished, it gives a very smooth surface. Pure marble is white in color. Some impurities present in the marble appear as a spot or a streak of different color. Taj Mahal is built up of white marble.

Pumice is a sort of porous rock having a rough surface. It is used in polishing floors and furniture.

Sand stone is formed when layers of sand harden into rocks. It is generally red in color. It is found in north India. Red fort in Delhi is built of sand stones.

Precious stones or gems are also tiny forms of rocks. They get their color and structure due to the metallic component present in them. Presence of cobalt gives deep blue color. Some of the gem stones are sapphire, opal, ruby, emerald etc. they are cut into required size shape, polished and then used in making jewelers.

Pebble and gravel are tiny form of rocks. Pebbles are small stones that would have become smooth and rounded by the action of flowing water. The stones are role and move in following water and get rounded off. We get pebbles of different shapes and sizes in river stream or on the sea shore.

Rocks and stones are dug out from the ground near the hills. This is known as quarrying. These dug out stones are cut into slabs as required. Stones are also crushed in to small pieces.
