What rock is soft and eaisly scratched?
Talc is a soft rock that is easily scratched. It has a hardness of 1 on the Mohs scale, making it one of the softest minerals.
What minerals are soft enough to be scratched by a fingernail?
Minerals that are soft enough to be scratched by a fingernail include gypsum (2 on the Mohs scale), talc (1), and calcite (3).
Which rock would be scratched with the finger?
A very soft rock like gypsum or talc would be scratched easily with a finger. Rocks like quartz, granite, or diamond would not be scratched by a finger.
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?
The mineral described is likely halite, also known as rock salt. Halite is colorless, often forms cubic crystals, has a lack of luster, and a hardness of around 2.5 on the Mohs scale, making it prone to being scratched by materials like fluorite.
How hard is biotite?
Biotite has a hardness of around 2.5-3 on the Mohs scale, which makes it a relatively soft mineral. It can be easily scratched with a knife or a nail.
What rock is soft enough to be scratched with a knife?
soapstone
What rock is soft and eaisly scratched?
Talc is a soft rock that is easily scratched. It has a hardness of 1 on the Mohs scale, making it one of the softest minerals.
Can talc be scratched by a steel nail?
Yes, because talc is very soft.
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).
Can sulfur be scratched by a nail?
No, sulfur cannot be easily scratched by a nail because it is a relatively soft material compared to metals like iron or steel. Sulfur has a Mohs hardness of 1.5–2, while iron nails typically have a hardness of 4-5 on the Mohs scale.
What minerals are soft enough to be scratched by a fingernail?
Minerals that are soft enough to be scratched by a fingernail include gypsum (2 on the Mohs scale), talc (1), and calcite (3).

What is the metamorphic rock composed of the mineral Talc?
Soapstone is a metamorphic rock composed of the mineral talc. Soapstone is a non-foliated metamorphic rock with a microcrystalline texture. It is very soft and can be easily scratched.
Can graphite be scratched by a fingernail?
Yes, graphite is a relatively soft mineral with a hardness of 1-2 on the Mohs scale. This means it can be easily scratched by materials with a higher hardness, such as a fingernail, which typically has a hardness of around 2.5.
How hard is biotite?
Biotite has a hardness of around 2.5-3 on the Mohs scale, which makes it a relatively soft mineral. It can be easily scratched with a knife or a nail.
Why is wax easily scratched?
