Talc (a common metamorphic mineral).
If a fingernail can scratch a mineral, you are testing the mineral's hardness. Hardness is a measure of a mineral's resistance to being scratched by other materials. Minerals are ranked on the Mohs scale of hardness from 1 (softest) to 10 (hardest).
It is talc
Talc has a hardness of 1 on the Mohs scale, making it one of the softest minerals.
it is a geological scale that measures the hardness of different minerals. Talc being the softest and a diamond being the hardest.
Talc is the softest mineral on the Mohs hardness scale. It has a hardness of 1 and can be easily scratched by other minerals.
If a fingernail can scratch a mineral, you are testing the mineral's hardness. Hardness is a measure of a mineral's resistance to being scratched by other materials. Minerals are ranked on the Mohs scale of hardness from 1 (softest) to 10 (hardest).
The Mohs' hardness scale is a scale that measures the hardness of minerals by testing their scratch resistance. It ranges from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. This scale is widely used in geology and mineralogy to identify minerals based on their scratch resistance.
It is talc
Talc is the softest mineral on the Mohs hardness scale, with a rating of 1. It can be easily scratched with a fingernail.
One of the softest is talc. It defines "1" on the Mohs scale of hardness.
The hardness of a mineral is determined using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). This scale is based on the ability of a mineral to scratch another mineral. To test the hardness of a mineral, various methods can be used, such as scratching it with a known mineral or using a tool like a hardness testing kit.
Talc is the softest mineral on the Mohs hardness scale, with a hardness of 1. It is composed of hydrated magnesium silicate and is commonly used in the production of talcum powder.
The softest mineral is talc, and the hardest is diamond. You can check this on the Mohs hardness scale.
The hardest mineral is diamond, and the softest mineral is talc.
Talc has a hardness of 1 on the Mohs scale, making it one of the softest minerals.
i think sulfur is the softest and crystal is hardest
The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
