Metamorphic Rocks and Marble Sculpting

Metamorphic rocks are formed from igneous, sedimentary, or other metamorphic rocks under intense heat and pressure deep beneath the Earth's surface. This process, known as metamorphism, changes the rock's form without melting it. Examples include slate from shale and marble from limestone. Metamorphic rocks are dense, non-porous, and have unique mineral structures, making them useful in construction and art. Marble, for instance, is prized for its carving ease, as seen in famous sculptures like Michelangelo's David.

What are the primary conditions that lead to the formation of metamorphic rocks?

• Erosion and weathering

• Deposition and compaction

• Heat and pressure

• Cooling and solidification
