Metamorphic rock
marble
When subjected to intense heat and pressure, coal can turn into diamonds.
Bituminous coal is changed by heat and pressure into the metamorphic rock anthracite.
Heat it.
marble
Diamond, which like , graphite, is an allotrope of carbon . If you heat diamond it weill turn to graphite.
Both
marble
Marble, an intermediate grade metamorphic rock.
Clays would become shale, then metamorphose into slate with heat and pressure.
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
No. Marble is metamorphosed limestone, recrystallized from heat, pressure, or both.
Limestone.
pressure, heat, time
Limestone/chalk. Limestone has been subjected to heat and/or pressure, it metamorposes into marble. Both limestone and marble are calcium carbonate (CaCO3). Its just that the internal physical structure of limestone is altered.
Limestone was probably metamorphed into marble.
it becomes a shale rock. There is no way that chalk, a form of limestone, can be metamorphosed into shale. It will like limestone change to marble.
No. Limestone changes to Marble when it undergoes intense heat and pressure.
