Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals. I'll go out on a limb though, and suggest that slate is probably around 2 to 3 or so, but this will be variable, depending on the quality of the slate, and degree of weathering, etc. Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals.
Slate is a metamorphic rock. Slate is actually shale that had low heat and not very much pressure put on it. Slate is mostly formed in mountain areas. It takes thousands of years for slate to change. Slate can be any color but is mostly found in gray or black.
