Definition
Metamorphic rocks are formed from the alteration of existing rocks through heat, pressure, and chemically active fluids, resulting in significant changes in mineral composition and texture.
Summary
Metamorphic rocks are a fascinating category of rocks that form through the transformation of existing rocks under heat and pressure. This process, known as metamorphism, can significantly alter the mineral composition and structure of the original rock, resulting in unique characteristics. Metamorphic rocks can be classified into foliated and non-foliated types, each with distinct features and formation conditions. Understanding these rocks is essential for various applications, including construction and geological studies. The study of metamorphic rocks not only enhances our knowledge of Earth's processes but also highlights their importance in everyday life. From the marble used in buildings to the slate used in roofing, metamorphic rocks play a crucial role in our environment and economy. By exploring their formation, characteristics, and applications, students can gain a deeper appreciation for the dynamic nature of our planet.
