Talc is the softest kind of rock. It is most known for it's usage as a baby powder. It is important, when using talcum powder, to be sure the baby does not breathe it in, since it is bad for their lungs.
The hardness of a rock is called its "Mohs scale hardness." This scale ranks minerals and rocks based on their scratch resistance, with diamond being the hardest at 10 and talc being the softest at 1.
The order of hardness from softest to hardest for the mentioned minerals is as follows: cinnabar, emerald, augite, sapphire, magnetite.
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.
The hardness of minerals is commonly ranked using the Mohs scale, which lists them in order from softest to hardest as follows: talc, gypsum, calcite, fluorite, apatite, orthoclase (feldspar), quartz, topaz, corundum, and diamond. Talc is the softest mineral, while diamond is the hardest. This scale helps in identifying minerals based on their resistance to scratching.
talc is the softest substance while daimond is th4e hardest substance on earth
The softest rock is generally talc, with a Mohs hardness of 1, while the hardest rock is diamond, with a Mohs hardness of 10. Other common rocks fall in between, such as gypsum (2), calcite (3), quartz (7), and feldspar (6-7).
The hardest mineral is diamond, and the softest mineral is talc.
diamond is the hardest and graphite is the softest
The hardest mineral is diamond, and the softest mineral is talc.
The softest mineral is talc, and the hardest is diamond. You can check this on the Mohs hardness scale.
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)
A diamond and talc
talc is the softest rock in the world while diamond is the hardest rock
number 10 is diamonds and the softest (number 1)is talc
There are about 20 grades of pencils from 9H the hardest, to F being the softest
The hardness of a rock is called its "Mohs scale hardness." This scale ranks minerals and rocks based on their scratch resistance, with diamond being the hardest at 10 and talc being the softest at 1.
