where is rock salt on the moths hardness scale
diamond
Schist is a composite material made up of a mixture of several minerals, each of which have different mohs hardness. Schist is made mostly of quartz (mohs 7) and feldspar (mohs 6) but also includes minerals such as chlorite (mohs 2) and hornblende (mohs 5). Schist has no real mohs hardness, but a composite of its constituents of approximately 6.
Halite, also known as rock salt, has a hardness of 2-2.5 on the Mohs scale. It is a relatively soft mineral that can be easily scratched with a fingernail or a pocket knife.
A rock's hardness is its resistance to scratching or abrasion. This is commonly measured using the MOH's scale of hardness.
Coal, as an organic sedimentary rock, is not determined to have a hardness on the Mohs scale of mineral hardness.
The Mohs hardness scale.
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.

this question is stupid
depends a rock made from lava is an igneous rock.
Bauxite falls between 1 and 3 on the Mohs Hardness Scale. This means that it is considered a relatively soft rock.
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
Slate, being a metamorphic rock, would not have a hardness listing on the Mohs scale of mineral hardness.
