Answer:
Marbles and granites are stones formed inside the earth through the cooling of the magma. Inside the earth, after the mantle, is located a deep layer of melted stone composed by reactions of radioactive elements, which ends up suffering a process of decomposition. The decaying material releases an intense heat wave that merges the stones around. The geological events, as the movement of plates or pressure, make the stones be pushed to the surface. When the rocks reach the surface occurs a cooling that originates igneous rocks, as granite and marble
