Factors like heat, pressure, and chemical reactions can contribute to the metamorphosis of a rock. These processes can alter the mineral composition and physical characteristics of the rock, leading to the formation of new types of rocks through metamorphism.
Metamorphic rock is formed from another kind of rock under great heat and pressure. This process alters the mineral composition and texture of the original rock, creating a new type of rock. Examples of metamorphic rocks include marble, schist, and gneiss.
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
Rock metamorphosis, or metamorphism, is the change in the crystalline components, chemical composition, or structure of rocks from exposure to intense pressure, heat, or exchange of ions through heated solutions. Metamorphosis of rock usually occurs deep below the Earth's surface, but could also occur from meteor impact, or close contact with a magmatic intrusion. Metamorphism occurs in rock without melting. Mineral components can recrystallize, form new minerals, and become aligned directionally in physical appearance. Through metamorphosis, one type of rock becomes another type of rock. Sandstone can become quartzite, limestone can become marble, shale can become slate, and so on. High pressures and temperatures can cause hydrous minerals to change to non-hydrous minerals like garnet. Rounded mineral crystals can become flattened, and minerals that grow in the stressed rock can display a preferred orientation that is perpendicular to the direction of the stress and display a characteristic known as foliation, with distinct banding or platyness. In rocks such as quartzite and limestone, where the minerals are relatively stable along a broad range of temperatures and pressures, the mineral crystals simply become larger. In cases where the metamorphism occurs because of proximity to hydrothermal fluids, a chemical exchange will take place, changing the original composition of the host rock.
The factors that contribute to making rock more rigid in the mantle include high pressure, low temperature, and the composition of the rock itself. These conditions cause the rock to be less able to flow or deform easily, resulting in increased rigidity.
Yes, moss growing on the surface of a rock can contribute to chemical weathering. As mosses grow, they produce organic acids that can break down minerals in the rock, leading to the formation of pits and crevices. Over time, this process can weaken the rock and contribute to its overall weathering and erosion.

Marble
Limestone is a sedimentary rock but due to metamorphosis it turns to Marble, a metamorphic rock.
Conditions such as high temperature and pressure, chemical reactions, and exposure to fluids like water can lead to the metamorphosis of a rock. These processes can change the mineral composition and structure of the rock, resulting in the formation of new rock types such as gneiss, schist, and marble.
Metamorphosis
The metamorphosis of a caterpillar into a butterfly is one of the most common examples of significant change in the stages of life.
This stage is known as imago. It is the final stage in the process of metamorphosis, and is when the insect gains adult maturity.
hard as a rock that is hard with extra hard bits
Metamorphosis rock refers to a type of rock that has undergone significant changes in appearance, structure, or composition due to high pressure, temperature, or chemical processes within the Earth's crust. This transformation typically involves recrystallization of minerals, resulting in the formation of new rock types such as marble from limestone or schist from shale.
metamorphosis a very slow process
A rock can be altered compositionally by chemical weathering or by metamorphosis through heat and pressure.
