Metamorphic rocks
Metamorphic rocks are types of rocks that have changed from their original form due to intense heat, pressure, or chemically active fluids within the Earth. This transformation can alter their mineral composition and texture, resulting in new rock types. Common examples include schist and marble, which originate from shale and limestone, respectively. The process of metamorphism can create distinct layers or crystalline structures, reflecting the conditions under which they formed. Metamorphic rocks are often found in mountainous regions, revealing the Earth's dynamic geological processes over millions of years.

Metamorphic rocks are types of rocks that have changed from their original form through heat, pressure, or chemically active fluids over long periods of time. This process, called metamorphism, transforms igneous or sedimentary rocks into new types with different mineral compositions and structures. A common example is granite turning into gneiss. Metamorphic rocks often display unique textures and layers, reflecting the conditions they underwent. They are commonly found in mountainous regions and are important for understanding the Earth's geological history.
