Bauxite falls between 1 and 3 on the Mohs Hardness Scale. This means that it is considered a relatively soft rock.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
It's called the Ore
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.

Nickel has a hardness of 4 on the Mohs scale.
The hardness is 3-4 on Mohs scale.
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
The Mohs scale is used to determine the relative hardness of minerals.
Breccia does not have a streak as it is a type of rock composed of angular fragments cemented together. The hardness of breccia can vary depending on the composition of the fragments and the cementing material, but it typically ranges from 3 to 7 on the Mohs scale of mineral hardness.
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness scale.
This scale was proposed by the Austrian geologist Friderich Mohs.
