(which is itself a biogenic sedimentary rock, a form of limestone), and coal (derived from the remains of tropical plants and subjected to pressure).

Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

Apr 30, 2009· Hi, does anyone know the formation of chalk, limestone and marble ? We have to do this gapfill, but I don't know some of the words. If you could help in any way, I will be very pleased :D.

Limestone. Limestone is also a sedimentary rock, but it is more compacted than chalk. It is formed from the remains of microscopic animals or foraminifera. Marble. Marble is a coarsecrystalline, metamorphic rock, which is formed when chalk or limestone are recrystallised under conditions of .

Chalk and marble are forms of limestone. They are all made of Calcium Carbonate.

Limestone and chalk are both primarily calcium carbonate with a small amount of silicates in the form of clay or silt. Adding strong acids like hydrochloric acid to chalk or limestone causes them to bubble as the acid reacts with the calcium carbonate to form CO2.

Chalk is a soft, white, porous form of limestone. It is relatively resistant to erosion and slumping, compared to the clays with which it is usually associated. Consequently, it forms tall, steep cliffs where chalk ridges meet the sea.

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve.
