GENERAL GEOLOGY

Detailed explanation-1: -Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Detailed explanation-2: -Deep inside the Earth, intense heat and pressure can change rocks into entirely new metamorphic rocks. In fact, the conditions are so extreme, they can change the rock’s texture, color, and the shape of its crystals. Even the rock’s minerals are broken down and new ones are formed.

Detailed explanation-3: -The process of formation of metamorphic rocks starts with existing rocks. Then, they undergo some sort of change due to immense heat or pressure. For example, a rock made of sand is “metamorphosed” into another type of rock when it comes in contact with intense heat.

Detailed explanation-4: -Sedimentary rock can become a metamorphic rock when exposed to higher levels of heat and pressure over time. These forces cause the minerals in the sedimentary rock to shift and realign into a different crystalline structure.
