What rock is soft enough to be scratched by a nail?
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
Can talc be scratched by a fingernail?
Talc i assigned a hardness of 1 according to the Mohs scale of hardness. This implies that talc has the least hardness and therefore is soft and can be scratched by a fingernail.
What is a mineral that has a colorless chunk that breaks apart into cubes it has no luster and is soft enough to be scratched by fluorite?
Halite, a colorless chunk that breaks apart into cubes and has no luster and is soft enough to be scratched fluorite, and when it gets wet it starts to dissolve. Did that help you?
What rock is soft and eaisly scratched?
as part of my science homework we have to give an example of a rock which is soft and easily scratched but I don't know what rock that is please help?
How can one determine the hardness of a mineral using Mohs scale need explain the technique and what is Mohs scale?
The Mohs Scale of Hardness is used to measure hardness of a mineral, which is its resistance to scratching. It is a quantitative scale, which relies on the relative hardness of other minerals . Higher numbered minerals scratch lower numbered ones. You can use every day objects like a glass plate, a knife, or a nail to distinguish hard and soft. Hard minerals scratch glass, but can't be scratched with a knife blade of a nail. Soft minerals will not scratch glass, but can be scratched with a knife blade or masonry nail. You can purchase hardness kits to help make these distinctions.

soapstone

Can a fingernail scratch some minerals?
Yes. But only soft ones such as talc (solid form of chalk and baby powder). Generally only minerals below 2 on the hardness scale.
What is halite's hardness on mohs scale?
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.
What is the hardness scale of kaolinite on the mohs scale?
Kaolinite has a hardness of approximately 2-2.5 on the Mohs Scale. This means it is relatively soft and can be easily scratched by harder minerals.
What rock has colourless chunk that breaks apart into cubes and has no lustre and is soft enough to be scratched by fluorite?
Calcite perhaps (although it does not form cubes).
