Metamorphic processes involve the transformation of pre-existing rocks under the influence of high temperature, pressure, and chemically active fluids, resulting in the formation of metamorphic rocks with new mineral assemblages and textures. These processes occur deep within the Earth's crust and are crucial for understanding the dynamic geological history and tectonic activities of our planet.

Pressure is the force exerted per unit area on the surface of an object, which can arise from various sources such as gases, liquids, or solids. It plays a crucial role in numerous scientific and engineering applications, influencing phenomena ranging from weather patterns to the behavior of gases and liquids in different environments.

Metamorphic rocks are formed through the transformation of existing rock types, in a process called metamorphism, which means 'change in form'. This transformation occurs under conditions of high pressure and temperature, leading to physical and chemical changes in the rock's mineral composition and structure without the rock melting.

The Earth's crust is the outermost solid shell of our planet, composed of a variety of rocks and minerals, and is the thinnest of Earth's layers. It is divided into continental and oceanic types, with the former being thicker and less dense, while the latter is thinner and denser, playing a crucial role in tectonic activity and the formation of geological features.
