Metamorphic rocks are formed when igneous or sedimentary rocks melt together by high heat and pressure, or as a result of exposure to fluids rich in hot minerals, or from a combination of these factors, and these conditions are indicated in the depths of the earth, or in the areas where tectonic plates meet, and these rocks are formed. Under the ground due to the accumulation of layers of rocks that form the surface of the earth through various geological processes, and with the passage of time the weight of the modern surface layers pushes the old layers down, which leads to an increase in temperature, pressure, and gravity on these rock layers; Which leads to a gradual transformation of the characteristics of these rock formations.
