Why is limestone changed into marble?

Answer 1

Limestone is softer than marble because of how they are formed inside. Marble consists of tightly interlocked crystals, which makes it stronger than limestone.

Limestone consists of small fossil fragments and smaller crystals, which makes it weaker than marble.

Answer 2

Marble is made up of interlocking crystals that fit together perfectly like a jigsaw, this makes it harder to break so therefore it is stronger. Limestone is made up of calcite grain that have been stuck together so they don't actually fit together properly.

Answer 3

because limestone it broken down by co2 in the rain in the form of carbolic acid, ph of aprox 5.6, and sandstone is made of hard sillica grains that depending on there matrix or "glue" will weather relativly slower than caco3 or limestone! i think thats it i only do a-level- brad ticehurst east sussex

Answer 4

The mineral grains in marble are formed from the recrystallization of calcite that was present in limestone or dolostone. Because of this recrystallization, the calcite crystals are interlocked. Limestone is usually composed of cemented grains of calcite material, not interlocked crystals, thus marble is sturdier and more resistant to fracturing.

Answer 5

There is metamorphic processes inside the earth.Due to extreme pressure,limestone changes into marble with near carbon atoms.Mrble is a metamorphic form of limestone.

Answer 6

Generally, yes, because marble consists of recrystallized minerals which are interlocked.

Answer 7

It is because it is more softer, less retractable

Answer 8

High heat and pressure cause the calcite in the limestone to recrystallize into larger crystal structures

Answer 9

because there dick isnt hard

Answer 10

Limestone.
