What is formed when limestone is changed by heat and pressure?

Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. Which rock is formed when heated and compressed over time? Metamorphic rocks. Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be ...

How Marble is Made For marble to be made it needs two things: heat and movement. When a regional area of limestone is heated, either at a place of convergence between two of the earth's plates or as a result of magma within the earth as a heat source, the calcite crystals within the limestone begin to grow and recrystallize.
