We cannot go to the centre of the earth. From surface to interior of the earth temperature and heat go on increasing. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Sedimentary rocks are formed from sediments.

Limestone is changed into marble due to the following reasons. Marble is a metamorphic rock resulting from regional or rarely contact metamorphism of sedimentary carbonate rocks either limestone or dolostone. Due to pressure and heat the original limestone changes into marble g. It is about 4 km.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. These sediments are transported and deposited by wind water etc. Now limestone is a type of sedimentary rock that under heat and pressure changes into marble which is a metamorphic rock. When it is subjected to conditions of extreme heat and pressure it gets converted into marble which is a metamorphic rock.
