Why is garnet found deep under the surface of Earth?

Explanation:

Garnet is found deep under the surface of Earth because it is formed under a great deal of pressure. Garnet is a mineral that typically forms in metamorphic rocks, which are rocks that have been subjected to high heat and pressure deep within the Earth's crust. When the rocks containing garnet are buried deep underground, the intense pressure and temperature cause the minerals within the rock to recrystallize and form new minerals like garnet.

Pressure plays a crucial role in the formation of garnet. The pressure helps to compact the minerals together and rearrange their atomic structure to form the distinct crystal structure of garnet. This process typically occurs at depths of several kilometers beneath the Earth's surface where the pressure is high enough to facilitate the transformation of minerals into garnet.

Unlike some minerals that are formed from volcanic activity or surface processes, garnet is primarily formed in the Earth's crust at depths where the pressure is significant. This is why garnet is often found deep underground and not near the surface. The process of garnet formation is slow and requires specific geological conditions to occur, making it a mineral that is typically found deep within the Earth.
