What else can I help you with?
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?
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.
How hard is biotite?
it is not hard because you can split the mineral
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 you are describing is likely halite, which is commonly known as rock salt. Halite is colorless, forms cubic crystals, has a dull luster, and a hardness of 2.5 on the Mohs scale, which is softer than fluorite. Its characteristic cubic cleavage and lack of luster are key identifying features.
What rock is soft enough to be scratched with a knife?
soapstone
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?
Can talc be scratched by a steel nail?
Yes, because talc is very soft.
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 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).
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.
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.
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.
How hard is biotite?
it is not hard because you can split the mineral
Why is wax easily scratched?
Because it is soft
Which rock type can be scratched with the fingernail?
The rock type that can typically be scratched with a fingernail is sedimentary rock, particularly soft varieties like limestone or chalk. These rocks generally have a hardness of 2 to 3 on the Mohs scale, making them softer than a fingernail, which has a hardness of about 2.5. This property allows for easy scratching and is a useful field test for identifying rock types.
