Is mantle a rock or metal?

Is mantle a rock or metal?" This question indeed piques my curiosity. Mantle, in its literal sense, often refers to a covering or cloak worn by someone, particularly in a royal or ceremonial context. It doesn't immediately seem to correlate with either rocks or metals. However, if we delve deeper and consider the word's potential etymological roots or figurative meanings, we might find some hints. Rocks are solid, natural formations, often found in the earth's crust, while metals are a class of elements that possess certain physical properties like conductivity and malleability. Now, if "mantle" is being used in a metaphorical sense to describe something solid, durable, or protective, it might be comparable to a rock. Rocks are known for their stability and enduring nature. On the other hand, if it's being used to describe something shiny, strong, or useful in a technological sense, it might be more akin to a metal. Metals are often valued for their utility and versatility. Without more context, it's difficult to definitively answer this question. "Mantle" could have various meanings depending on its usage and the context in which it appears. If you have more information or a specific context in which the word is used, I'd be happy to delve further into the matter and provide a more detailed answer.
