How hard is a metemorphic rock?

Metamorphic rocks can vary widely in hardness depending on their mineral composition and the conditions under which they formed. Generally, they tend to be harder than sedimentary rocks but can be softer than some igneous rocks. For example, schist and slate can be relatively softer, while gneiss and quartzite are typically much harder. Overall, hardness can be assessed using the Mohs scale, with many metamorphic rocks falling between 5 and 7.
