The process is called metamorphism, the alteration of chemical composition or structure due to heat and/or pressure.
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
Chemical weathering causes the mineral composition of a rock to change. This process involves the breakdown of minerals in the rock due to chemical reactions with water, oxygen, or acids in the environment. Over time, these reactions can alter the original minerals into different ones.

Yes, weathering is the process by which rocks are broken down and their mineral composition can be altered. This can occur through physical weathering (mechanical breakdown of rocks) and chemical weathering (alteration of minerals through chemical reactions with water, oxygen, or other substances). Over time, this process can lead to the formation of new minerals and the breakdown of original mineral compositions in rocks.
The mineral composition of a rock can change due to processes like metamorphism, which involves high pressure and temperatures altering the minerals present in the rock. Weathering and hydrothermal activity can also change the mineral composition by leaching out certain minerals and depositing new ones. Additionally, volcanic activity and magma intrusion can introduce new minerals into existing rocks through the process of crystallization.
An agent of metamorphism related to temperature is heat. Heat causes minerals in rocks to recrystallize or change mineral composition, leading to metamorphic changes in the rock. Temperature influences the degree of metamorphism and the types of minerals that form during the process.
A mineral's density remains constant unless there is a change in its composition or structure. Factors such as pressure, temperature, and chemical reactions can alter a mineral's density.
A mineral phase change occurs when a mineral undergoes a transformation in its crystal structure due to changes in temperature, pressure, or composition. This can impact the properties of the mineral by altering its hardness, density, color, and other physical characteristics.
